When I’m choosing the best red dot sight for the Glock 19 Gen 6, I look for a combination of reliable mounting compatibility, clear optics, durable construction, useful reticle options, and dependable battery performance.
The red dots I’ve considered stand out for features such as multiple reticle configurations, large viewing windows, Shake Awake technology, long battery life, rugged housings, and enclosed emitter designs.
Since the Gen 6 uses its newer ORS mounting system, I also pay close attention to footprint and adapter requirements before recommending any optic. In this guide, I’ll cover the key features to look for, my top picks, a practical buying guide, and frequently asked questions to help you choose the right red dot for your Glock 19 Gen 6.
Best Red Dot Sight For Glock 19 gen 6
1) Holosun 407C X2
The Holosun 407C X2 is a strong choice for shooters looking for a durable, feature rich red dot sight for the Glock 19 Gen 6, but there is one important compatibility detail to understand before buying.
The 407C X2 uses the RMR footprint, while the Glock 19 Gen 6 uses Glock’s newer ORS (Optic Ready System) mounting pattern. Because these footprints are different, the 407C X2 does not mount directly to the Gen 6 slide out of the box.
A compatible Gen 6 ORS to RMR adapter plate, such as the DPP Titanium Gen 6 ORS RMR Adapter or a C+H Precision Gen 6 ORS RMR Adapter, is required. Once the correct plate is installed, the 407C X2 offers a compelling combination of durability, battery life, visibility, and straightforward controls.
The 2 MOA red dot offers a precise aiming point without taking up excessive space in the window, making the optic suitable for shooters who want a clean reticle presentation.
Durability is another reason I would consider the 407C X2 for a Glock 19 Gen 6 setup. Holosun builds the housing from 7075 T6 aluminum, with an anodized surface finish designed to withstand the demands of regular use.
The optic also uses an industry standard footprint, although Glock’s Gen 6 ORS system means an adapter is necessary in this particular application. The combination of a robust housing and compact open reflex design makes the 407C X2 a practical option for a pistol that may see frequent range use.
The 407C X2 uses a CR1632 battery and is rated for up to 50,000 hours of battery life, depending on settings and conditions. Holosun’s Shake Awake technology helps conserve power by deactivating the LED when the sight is not being used.
The optic can be configured with different activation time settings, ranging from approximately 10 minutes to 12 hours depending on the selected mode, and Shake Awake can also be disabled if preferred.
When movement is detected, the LED quickly reactivates, reducing the need to manually operate the optic every time it is needed.
In Auto Mode, the system can also automatically adjust reticle intensity according to available light. Brighter environments produce a brighter reticle, while the intensity decreases in lower light. This can help maintain a visible aiming point across changing lighting conditions while reducing dependence on the battery alone.
The Lock Mode feature is particularly useful for preventing accidental changes to the optic’s settings. Once the desired brightness configuration has been established, Lock Mode can help prevent inadvertent button presses from altering those settings during handling or use.
The 407C X2 provides 10 daylight brightness settings and 2 night vision settings, giving users flexibility when adjusting the reticle for different environments.
The 407C X2 provides 1 MOA adjustment per click with a windage and elevation travel range of ±50 MOA. These adjustments allow the shooter to zero the optic and make precise corrections when necessary.
Combined with the 2 MOA dot and 1x magnification, the adjustment system gives the optic a straightforward setup for users who prefer a simple, precise aiming solution.
Compatibility is the main consideration when pairing this optic with the Glock 19 Gen 6. The 407C X2’s RMR footprint does not directly match the Gen 6 ORS slide, so it cannot simply be installed using the factory mounting system. A dedicated Gen 6 ORS to RMR adapter plate is needed to bridge the two mounting patterns.
Options such as the DPP Titanium Gen 6 ORS RMR Adapter and C+H Precision Gen 6 ORS RMR Adapter have been recommended for mounting RMR footprint optics on the Gen 6 ORS system.

The Holosun 407C X2 is a capable and feature rich red dot sight that makes sense for a Glock 19 Gen 6 when installed with the appropriate adapter plate. Its 2 MOA dot, large viewing window, 7075 T6 aluminum housing, long battery life, Shake Awake, Solar Failsafe, and Lock Mode give it a well rounded feature set for a modern pistol optic.
2) Holosun 507C X3
The Holosun 507C X3 is a versatile pistol red dot that brings a useful combination of reticle flexibility, durability, automatic brightness control, and long-term reliability to the Glock 19 Gen 6. However, there is an important mounting consideration before adding it to this pistol.
The 507C X3 uses the RMR/407C/507C footprint, while the Glock 19 Gen 6 uses the newer ORS (Optic Ready System) mounting pattern. As a result, the optic does not mount directly to the Gen 6 ORS slide. A compatible Gen 6 ORS to RMR adapter plate is required. With the correct adapter, the 507C X3 becomes a practical option for shooters who want a rugged optic with multiple reticle choices and a broad set of modern features.
One of the biggest advantages of the Holosun 507C X3 is its Multi Reticle System (MRS). The optic provides a 2 MOA dot and 32 MOA circle, allowing the shooter to choose between a precise dot, a larger circular aiming reference, or a combination of both.
This flexibility can make the sight easier to configure according to personal preference and lighting conditions. The available 507C X3 configurations include red, green, and gold reticle options, although the specific model selected determines which reticle color is provided.
The 2 MOA dot offers a relatively precise aiming point, while the 32 MOA circle can provide a larger visual reference that may help with rapid sight acquisition. Having multiple reticle presentations in one optic also means users can experiment with different configurations rather than being locked into a single reticle design.
The 507C X3 incorporates a forward-facing photodiode with Solar Failsafe technology. This system can automatically adjust the reticle brightness according to the available lighting conditions, helping maintain visibility as the environment changes. The solar system also provides an additional power source when sufficient ambient light is available.
Manual brightness controls give the shooter additional control when automatic adjustment is not preferred. The optic provides 12 brightness settings, allowing the reticle to be configured for different lighting environments. Lockout and memory modes further help maintain the desired settings once the optic has been configured.
Holosun’s Shake Awake technology is another useful feature for a pistol-mounted optic. Instead of leaving the LED illuminated continuously, the system can deactivate the reticle after a period of inactivity to conserve energy. Movement then activates the optic, allowing the reticle to return when the sight is handled.
This approach helps balance readiness with battery conservation. For users who keep the optic configured and ready for use, Shake Awake reduces the need to manually activate the sight every time it is picked up or moved.
The 507C X3 is built around a 7075 T6 aluminum housing with a hard-anodized finish. This material provides a strong and durable platform while keeping the optic suitable for pistol applications. The sight is also rated IP67 waterproof and designed to withstand up to 5000G of vibration resistance, giving it a robust construction for regular use.
The combination of the aluminum housing, waterproof rating, and vibration resistance makes the 507C X3 a sensible choice for users who place a high priority on durability. The rugged construction also complements the Glock 19 platform, which is commonly selected for its compact size and practical design.
The optic uses multi-coated lenses and provides a parallax-free viewing experience with unlimited eye relief. These characteristics make the sight easier to use without requiring a specific eye position behind the optic. The generous viewing area also helps maintain awareness of the target and surrounding environment while looking through the sight.
Mounting compatibility is the most important issue to consider before purchasing the 507C X3 for a Glock 19 Gen 6. The optic uses the RMR footprint, but the Gen 6 Glock 19 uses Glock’s newer ORS mounting pattern, which differs from the Gen 5 MOS system.
Therefore, the 507C X3 will not mount directly to the Glock 19 Gen 6 ORS slide. A dedicated Gen 6 ORS to RMR adapter plate is needed. Suitable options include the DPP Titanium Gen 6 ORS RMR Adapter in aluminum or titanium PVD versions, as well as a C+H Precision Gen 6 ORS RMR Adapter.

The Holosun 507C X3 is a strong choice for the Glock 19 Gen 6 when paired with the appropriate mounting adapter. Its Multi Reticle System, 2 MOA dot, 32 MOA circle, Solar Failsafe, Shake Awake, 12 brightness settings, rugged 7075 T6 housing, IP67 waterproof rating, and 5000G vibration resistance give it a well-rounded feature set for a modern pistol red dot.
3) OSIGHT C Micro Red/Green Dot Open Reflex Sight
The OSIGHT C Micro Red/Green Dot Open Reflex Sight is a feature rich option for the Glock 19 Gen 6, particularly for shooters who want a flexible reticle, large field of view, and convenient battery access.
The optic uses the 407C/507C RMR footprint, so it does not mount directly to the Glock 19 Gen 6’s newer ORS slide. However, it can be installed with a compatible Gen 6 ORS to RMR adapter plate.
A community user has specifically confirmed having the OSIGHT C mounted on a Glock 19 Gen 6, making it a practical option when the correct adapter is used. Recommended adapter choices include the DPP Titanium Gen 6 ORS RMR Adapter and C+H Precision Gen 6 ORS RMR Adapter.
The OSIGHT C Micro is designed for slides cut for the Ruggedized Miniature Reflex 407C/507C footprint, commonly referred to as the RMR footprint. The product listing specifies that other slide patterns require an adapter plate, which is important for the Glock 19 Gen 6.
Since the Gen 6 Glock 19 uses the newer ORS mounting system, the OSIGHT C cannot be attached directly to the factory optic cut. A dedicated Gen 6 ORS to RMR adapter plate is required. Options such as the DPP Titanium Gen 6 ORS RMR Adapter in aluminum or titanium PVD and the C+H Precision Gen 6 ORS RMR Adapter can provide the necessary interface.
The fact that a community user reports successfully mounting the optic on a Glock 19 Gen 6 further supports its compatibility when the appropriate adapter is used.
The OSIGHT C gives shooters several reticle configurations through its 3 MOA dot and 32 MOA circle. You can select the dot and circle combination, use the dot alone, or select the circle alone. This provides flexibility when deciding how much visual information you want in the sight picture.
The 3 MOA dot provides a relatively precise aiming reference, while the larger 32 MOA circle creates a more prominent visual reference that can assist with quick sight acquisition. Having three reticle presentations available allows the user to select the configuration that feels most intuitive for different shooting conditions.
Another useful characteristic is the OSIGHT C’s large viewing window. A larger sight picture can make it easier to locate the reticle and maintain visual awareness around the aiming point. This can be particularly helpful when transitioning from traditional iron sights to a red dot.
The optic also uses multi-coated lenses with anti-reflective coatings designed to improve light transmission and maintain clarity. Better light transmission can help produce a clearer sight picture, while the larger window provides more visual space for target acquisition and follow-up shots.
The side loading battery compartment makes battery replacement considerably more convenient because the optic does not need to be removed from the slide to access the battery. This is useful because removing an optic can potentially require the sight to be re-zeroed.
Keeping battery access on the side allows the OSIGHT C to remain mounted while the battery is replaced. For a pistol optic that may be used regularly, this is a practical design choice that simplifies maintenance and helps preserve the existing zero.
The OSIGHT C also incorporates a motion sensor designed to activate the optic when movement is detected. The system powers down after approximately three minutes of inactivity, helping conserve battery power when the sight is not being used.

- Motion sensor automatically activates the optic with movement
- Automatic shutdown after three minutes of inactivity helps conserve battery
- RMR footprint is widely supported with appropriate mounting solutions
Cons
- Does not directly mount to the Glock 19 Gen 6 ORS slide
The OSIGHT C Micro Red/Green Dot Open Reflex Sight is an appealing choice for the Glock 19 Gen 6 because it combines a 3 MOA dot, 32 MOA circle, multiple reticle configurations, large field of view, multi-coated lens, side loading battery, and motion sensor activation in a compact open reflex design. Its battery access is especially convenient because the optic can remain mounted while the battery is changed.
4) OSIGHT XE AMRS Enclosed Red Dot Sight
The OSIGHT XE AMRS Enclosed Red Dot Sight is an intriguing option for the Glock 19 Gen 6, especially for shooters who want the added environmental protection of an enclosed emitter combined with an unusually flexible reticle system.
The optic uses the 407C/507C RMR footprint, so it does not mount directly to the Glock 19 Gen 6’s newer ORS slide. A compatible Gen 6 ORS to RMR adapter plate is required for installation.
With the correct adapter, the XE AMRS offers several useful features, including a five configuration AMRS reticle system, an integrated collapsible backup rear sight, side loading battery access, motion activation, and an aspherical lens.
The enclosed emitter design is one of the most practical reasons to consider the OSIGHT XE AMRS for a Glock 19 Gen 6. Unlike an open reflex sight, the enclosed configuration protects the emitter from environmental contaminants that can interfere with the reticle.
Dust, dirt, moisture, and other debris are less likely to reach the enclosed emitter, making this design particularly appealing for users who prioritize reliability in changing conditions.
The XE AMRS uses the commonly used 407C/507C RMR footprint, which provides broad compatibility with many full size and compact pistol mounting systems. However, the Glock 19 Gen 6 uses the newer ORS mounting pattern, so the two patterns do not match directly. A Gen 6 ORS to RMR adapter plate is therefore necessary.
Recommended options include the DPP Titanium Gen 6 ORS RMR Adapter in aluminum or titanium PVD versions and the C+H Precision Gen 6 ORS RMR Adapter. Buyers should confirm the exact adapter specifications for their Gen 6 slide before installation.
This flexibility allows the reticle to be adjusted according to personal preference and shooting conditions. The 2 MOA dot provides a smaller aiming reference, while the 6 MOA dot creates a larger and more prominent point. Adding the 32 MOA circle provides another visual reference that can make the reticle easier to locate quickly.
A particularly unusual feature is the collapsible backup rear sight, which is integrated directly into the optic. With the press of the pop up button, the backup sight can be deployed if the electronic reticle is unavailable.
This gives the XE AMRS an additional aiming option without requiring a separate rear sight assembly to provide the same function. When the optic is operating normally, the rear sight can remain collapsed. If the optic is powered off, the integrated backup sight can be activated to provide an alternative sighting reference.
For a Glock 19 Gen 6 setup, this integrated approach can also help keep the overall sighting system streamlined while providing an additional layer of redundancy.
The side loading battery compartment makes routine maintenance easier because the battery can be replaced without removing the optic from the slide. This is especially useful for a pistol optic because removing and reinstalling an optic can potentially require the zero to be checked again.
The XE AMRS uses an aspherical lens designed to provide a clear sight picture with minimal distortion. The lens is also described as providing parallax free performance, which helps make the optic easier to use without requiring a perfectly centered eye position.
The OSIGHT XE AMRS includes Motion Activation Technology, which powers the optic on when movement is detected. After approximately three minutes of inactivity, the optic powers down to conserve battery power.
This automatic operation reduces the need to manually switch the optic on and off. Movement activates the reticle when the sight is handled, while the automatic shutdown helps limit unnecessary power consumption during periods of inactivity.
Another useful feature is the low power indication system. If the battery voltage falls below 2.2V, the reticle is designed to triple flash once per minute to indicate that the battery should be replaced.
Pros
- Enclosed emitter protects the reticle system from environmental debris
- Five reticle configurations provide excellent aiming flexibility
- Offers 2 MOA dot and 6 MOA dot options
- 32 MOA circle can be used alone or combined with either dot
- Integrated collapsible backup rear sight provides an additional aiming system
- Side loading battery allows replacement without removing the optic
- Aspherical lens is designed for clarity and reduced distortion
- Parallax free performance
- Motion activation automatically powers the optic on with movement
- Automatic shutdown after three minutes helps conserve battery
- Low power indication alerts the user when battery replacement is recommended
- Enclosed emitter design offers greater environmental protection than an open reflex optic
Cons
- Does not directly mount to the Glock 19 Gen 6 ORS slide
The OSIGHT XE AMRS is one of the more feature packed red dot options to consider for the Glock 19 Gen 6. Its enclosed emitter, five reticle configurations, integrated collapsible backup rear sight, side loading battery, aspherical lens, motion activation, and low power warning give it a broad feature set that goes beyond a conventional pistol red dot.
The main drawback is its mounting compatibility. Because the XE AMRS uses the 407C/507C RMR footprint and the Glock 19 Gen 6 uses the ORS system, an appropriate Gen 6 ORS to RMR adapter is required.
Once that issue is addressed, the XE AMRS offers a combination of enclosed emitter protection, reticle flexibility, and integrated backup sights that makes it a compelling candidate among the best red dot sights for the Glock 19 Gen 6.
5) Swampfox Liberty II RMR 1×24
The Swampfox Liberty II RMR 1×24 is a compact pistol red dot that offers a practical combination of a wide viewing window, rugged construction, automatic illumination management, and a slim profile.
It is particularly interesting for the Glock 19 Gen 6 because its universal RMR footprint makes it compatible with RMR mounting systems, but there is an important distinction with the Gen 6 slide.
The Glock 19 Gen 6 uses the newer ORS mounting pattern, so the Liberty II does not mount directly to the factory ORS cut. A Gen 6 ORS to RMR adapter plate is required.
With the appropriate adapter, the Liberty II provides a compact aiming solution with a 24mm window, 10 brightness settings, Shake N’ Wake technology, and a durable 7075 aluminum housing.
The Liberty II features a 24mm objective lens and a slim body designed to complement compact and full size pistol platforms. The relatively large viewing window provides plenty of visual space around the reticle, helping make target acquisition more natural when transitioning to a red dot sight.
Its slim profile also makes the Liberty II a practical choice for users who want a compact optic without an unnecessarily bulky housing. The design is compatible with duty grade holsters, which adds versatility for Glock 19 owners who want to maintain compatibility with their existing equipment.
Swampfox designed the Liberty II around a universal RMR footprint, one of the more widely used mounting patterns for pistol optics. This gives the optic broad compatibility across slides that are specifically cut for the RMR pattern.
However, the Glock 19 Gen 6 uses a different ORS mounting system. Consequently, the Liberty II cannot be installed directly onto the Gen 6 ORS slide. A dedicated Gen 6 ORS to RMR adapter plate is needed to bridge the two mounting patterns.
Recommended options include the DPP Titanium Gen 6 ORS RMR Adapter in aluminum or titanium PVD and the C+H Precision Gen 6 ORS RMR Adapter. I would verify the exact adapter and screw specifications for the particular Gen 6 slide before installation.
The Liberty II incorporates Shake N’ Wake technology, which automatically manages the illumination when the optic is not being used. After approximately 225 seconds without movement, the illumination shuts down to conserve battery power.
Once movement is detected again, the illumination immediately resumes at its previous brightness setting. This means the user does not have to manually turn the optic on every time it is handled, while the automatic shutdown helps reduce unnecessary battery consumption.
The Liberty II provides 10 brightness settings, giving the shooter plenty of flexibility when adjusting the reticle for different lighting conditions. The ability to manually select the appropriate illumination level can be useful when moving between bright outdoor environments and lower light.
The combination of manual brightness control and Shake N’ Wake technology provides a straightforward balance between reticle visibility and power conservation. Users can select their preferred brightness and allow the optic to remember that setting when it goes into its automatic sleep state.
The optic features a ruby red lens with fully multi-coated glass. Swampfox also applies anti-fog, anti-scratch, and hydrophobic coatings, which are intended to help maintain optical clarity under different environmental conditions.
The combination of 7075 aluminum and stainless steel gives the Liberty II a sturdy construction while maintaining its compact form. For a Glock 19 Gen 6, this provides a useful balance between durability and keeping the optic’s overall footprint manageable.
The top mounted battery cover makes battery access straightforward. Unlike optics that require removal from the slide before changing the battery, the Liberty II’s battery compartment can be accessed from above.
This design can simplify routine maintenance and reduce the need to disturb the optic’s mounting position when replacing the battery. For a pistol that is frequently used or regularly transported, convenient battery access can make long term ownership easier.
The most important purchasing consideration is the difference between the Liberty II’s RMR footprint and the Glock 19 Gen 6’s ORS mounting pattern. The Liberty II will not mount directly to the Gen 6 ORS slide.
Pros
- Universal RMR footprint
- Compatible with the Glock 19 Gen 6 when paired with the correct ORS to RMR adapter

Its coated ruby red lens also adds useful protection against fog, scratches, and water.
6) Swampfox Kingslayer Pistol Cut RMR Foot Print 1×22 Micro Reflex Dot Sights
The Swampfox Kingslayer Pistol Cut RMR Footprint 1×22 Micro Reflex Dot Sight is an affordable and compact option for the Glock 19 Gen 6, especially for shooters who want a simple pistol optic without spending as much as they would on premium alternatives.
With an RMR compatible footprint, 3 MOA dot, 10 brightness settings, and 800G shock resistance, the Kingslayer offers a practical feature set for its price of approximately $147.98.
However, there is an important compatibility consideration for the Glock 19 Gen 6: its newer ORS mounting pattern differs from the standard RMR cut. As a result, the Kingslayer does not mount directly to the Gen 6 ORS slide and requires a compatible Gen 6 ORS to RMR adapter plate.
The Kingslayer is designed around an RMR compatible footprint intended for reciprocating pistol slides. This is useful because the RMR pattern is widely supported across the pistol optic market and provides a familiar mounting standard for many handgun platforms.
For the Glock 19 Gen 6, however, the RMR compatibility does not mean direct installation. The Gen 6 uses the newer ORS mounting pattern, so the Kingslayer needs an adapter to bridge the difference. Suitable options include the DPP Titanium Gen 6 ORS RMR Adapter in aluminum or titanium PVD and the C+H Precision Gen 6 ORS RMR Adapter.
Once the appropriate adapter is installed, the Kingslayer can be used with the Glock 19 Gen 6. I would verify the exact adapter and screw specifications before installation to ensure the mounting hardware is appropriate for the particular slide.
The Kingslayer uses a 3 MOA dot, providing a straightforward aiming reference without adding unnecessary reticle complexity. A 3 MOA dot offers a useful middle ground between a very fine aiming point and a larger, more prominent dot.
The optic provides 10 brightness settings, giving the user control over reticle intensity in different lighting conditions. The additional adjustment levels make it possible to tune the dot for brighter environments while also lowering the intensity when shooting in darker surroundings.
This manual brightness control is useful for users who prefer to select their own reticle intensity rather than relying entirely on an automatic system. It also allows the shooter to establish a preferred setting before use.
The Kingslayer’s 1×22 micro reflex configuration keeps the optic compact while still providing a useful viewing area. Its small profile makes it well suited to pistol applications where excessive optic size can affect the overall balance and appearance of the firearm.
The compact format also makes the Kingslayer an attractive choice for someone who wants a minimal optic footprint. While the window is not as large as some full size pistol red dots, the 22mm viewing area provides enough space for a conventional 3 MOA dot.
Swampfox designed the Kingslayer with 800G shock resistance, giving it a level of impact resistance appropriate for a pistol mounted optic. Because a slide mounted red dot experiences repeated movement and acceleration during operation, durability is an important consideration.
The 800G rating helps demonstrate that the optic is designed to withstand the repeated stresses associated with a reciprocating slide. This is particularly relevant for users who intend to use the optic regularly rather than only occasionally at the range.
The Kingslayer package includes several accessories that add value to the purchase. Inside the box, you receive the optic with sheath, Picatinny rail mount, screwdriver, lens cloth, battery, and three screw sets.
Having multiple screw sets included can make installation more convenient when mounting the optic to a compatible platform. The included Picatinny rail mount also gives the optic additional versatility for applications where a rail mounted configuration is appropriate.
However, the Glock 19 Gen 6 adapter required for the ORS mounting system is a separate consideration. The included hardware should not be assumed to replace a dedicated Gen 6 ORS to RMR adapter.
At approximately $147.98, the Kingslayer is the most budget friendly optic among the models considered here. Its feature set is relatively straightforward, but it covers the essentials: a 3 MOA dot, 10 brightness settings, compact construction, and 800G shock resistance.
For someone who does not need advanced features such as multiple reticles, solar backup power, or an enclosed emitter, the Kingslayer can provide a more economical entry into pistol red dot shooting. The additional adapter cost for the Glock 19 Gen 6 should nevertheless be included when calculating the total setup price.
Pros

- RMR compatible footprint
- Compatible with Glock 19 Gen 6 when paired with the correct ORS to RMR adapter
- Simple 3 MOA red dot reticle
- 10 brightness settings
- Compact 1×22 micro reflex design
- 800G shock resistance
- Includes battery and multiple screw sets
- Includes Picatinny rail mount
- Includes protective sheath and lens cloth
Cons
- Does not mount directly to the Glock 19 Gen 6 ORS slide
The Swampfox Kingslayer Pistol Cut RMR Footprint 1×22 Micro Reflex Dot Sight is an appealing budget option for the Glock 19 Gen 6. Its 3 MOA dot, 10 brightness settings, 800G shock resistance, compact design, and included accessories provide the basic capabilities many users want from a pistol red dot without pushing the purchase price too high.
7) OSIGHT SE Enclosed Red/Green Dot
The OSIGHT SE Enclosed Red/Green Dot is a compelling option for the Glock 19 Gen 6 for shooters who want an enclosed emitter, flexible reticle system, convenient battery access, and a relatively affordable price.
At approximately $199.99, it combines a 2 MOA dot and 32 MOA circle Multi Reticle System with a fully enclosed design and aspherical lens. However, compatibility requires careful attention because the OSIGHT SE uses an RMSc/K footprint, while the Glock 19 Gen 6 uses the newer ORS mounting pattern. It therefore cannot mount directly to the factory Gen 6 ORS slide and requires a suitable Gen 6 ORS to RMSc adapter plate.
The fully enclosed design is one of the most appealing characteristics of the OSIGHT SE. Unlike an open emitter optic, its sealed construction protects the emitter and internal components from dust, dirt, moisture, and other environmental contaminants that could interfere with the reticle.
For a Glock 19 Gen 6 intended for everyday carry or regular outdoor use, this enclosed configuration can provide additional peace of mind. Keeping the emitter protected can also make routine maintenance easier because there is less exposed hardware around the reticle system that needs to be cleaned.
The OSIGHT SE features a Red Multi Reticle System that allows the user to switch between a dot and circle combination, dot only, or circle only. Its 2 MOA dot provides a relatively precise aiming point, while the 32 MOA circle creates a larger visual reference.
The ability to select between these configurations makes the optic adaptable to different preferences. Users who prefer a clean aiming point can select the dot alone, while those who want a more prominent reticle can use the circle or the combined dot and circle configuration.
The OSIGHT SE uses an aspherical lens designed to provide a clear sight picture with minimal distortion. Its parallax free performance helps make the optic easier to use without requiring the eye to remain in one precise position behind the sight.
The large viewing window also provides plenty of visual space around the reticle. This can make it easier to locate the aiming point quickly and maintain a broad sight picture during target acquisition and follow up shots.
The side loading battery compartment is another practical feature. Battery replacement can be completed without removing the optic from the slide, which means the user does not have to disturb the mounting position simply to install a new battery.
This is particularly convenient for a pistol optic because removing and reinstalling a sight can require the zero to be checked again. With side battery access, routine maintenance is simpler while the optic remains mounted.
The OSIGHT SE uses an RMSc footprint, making it intended for optics ready slides specifically cut for the RMSc pattern. This is an important distinction because the RMSc footprint is different from the RMR footprint used by several larger pistol optics.
The product information specifically indicates that non RMSc slides require an adapter plate. Since the Glock 19 Gen 6 uses the newer ORS mounting pattern, the OSIGHT SE does not directly fit the factory slide.
A dedicated Gen 6 ORS to RMSc adapter plate is therefore required. This should not be confused with the Gen 6 ORS to RMR adapters used with RMR footprint optics. Buyers should verify that the adapter is specifically designed to interface the Gen 6 ORS system with the RMSc footprint before purchasing.
The OSIGHT SE will not mount directly to the Glock 19 Gen 6 ORS slide because the two mounting patterns are different. However, it can be used on the pistol with the correct adapter.
The appropriate solution is a Glock Gen 6 ORS to RMSc adapter plate. The adapter must be specifically designed for the Gen 6 ORS system and the RMSc footprint. Because the required adapter is not included with the optic, it should be factored into the overall purchase and installation process.
At approximately $199.99, it also occupies a relatively accessible price point for an enclosed pistol optic. The stated lifetime warranty adds another benefit for buyers looking for long term ownership support.

Cons
- Does not mount directly to the Glock 19 Gen 6 ORS slide
The OSIGHT SE Enclosed Red/Green Dot is a strong option for the Glock 19 Gen 6 if you specifically want an enclosed emitter and RMSc footprint optic.
Its 2 MOA dot, 32 MOA circle, multiple reticle configurations, aspherical lens, large window, and side loading battery give it a practical feature set, while the fully enclosed construction offers greater protection from environmental contaminants than an open emitter design.
8) OM1 Red Dot Sight
The ZEROHAWK OM1 Red Dot Sight is an affordable and versatile option for the Glock 19 Gen 6, particularly for buyers who want multiple reticle choices, long battery life, lightweight construction, and several mounting options without spending a premium.
At approximately $119.99, it offers a 2 MOA and 6 MOA Multi Reticle System, Shake Awake technology, a side loading CR1632 battery, and a rugged 7075 T6 aluminum housing. The OM1 uses an RMSc/K footprint, so it does not directly mount to the Glock 19 Gen 6 ORS slide.
However, the optic includes both MOS to RMSc and RMR to RMSc adapter plates, potentially simplifying installation. Because the Gen 6 uses a newer ORS pattern, the included MOS adapter should be verified with the manufacturer before purchase to confirm that it fits the specific Gen 6 ORS cut.
The ZEROHAWK OM1 gives users the choice between a 2 MOA dot and 6 MOA dot, allowing the reticle to be tailored to different shooting preferences. The smaller 2 MOA dot provides a more precise aiming point, while the larger 6 MOA dot is designed to be easier to acquire quickly at closer distances.
This flexibility makes the OM1 appealing to shooters who want to use the same optic for different activities. A smaller dot can provide a cleaner aiming reference when precision is important, while the larger dot can offer a more immediately visible aiming point when speed is prioritized.
The OM1 features parallax free optics and a large viewing window designed to provide a clear sight picture. Its multi-layer coated lens helps reduce glare and maintain optical clarity, while the hydrophobic surface is designed to repel water and dirt.
These coatings can be useful in changing environmental conditions because moisture and debris are less likely to remain on the lens. Combined with the large viewing window, the optical system is designed to make it easier to locate the reticle and acquire the target quickly.
The OM1 is designed to fit RMSc footprint slides and comes with a particularly useful selection of mounting hardware. The package includes nine sets of anti-recoil mounting screws, along with both MOS to RMSc and RMR to RMSc adapter plates.
This is an advantage over optics that require the buyer to purchase an adapter separately. However, the Glock 19 Gen 6 uses the newer ORS mounting pattern, so the included MOS adapter should not automatically be assumed to be compatible. The manufacturer should be consulted to confirm that the supplied MOS to RMSc adapter is designed for the Gen 6 ORS cut.
If the included adapter is confirmed to fit, the OM1 could be considerably more convenient to install than many of the other optics considered for the Glock 19 Gen 6.
The OM1 uses a CR1632 battery and is rated for up to 50,000 hours of runtime in Mode 3. Its power efficient optical system is designed to reduce energy consumption while maintaining extended operation.
The side loading battery compartment allows the battery to be replaced without removing the optic from the firearm. This can help preserve the existing zero because the sight does not need to be taken off the slide simply to perform routine battery maintenance.
An integrated battery cap screw also helps prevent the small retaining screw from being lost during battery replacement. This is a useful detail for anyone who expects to maintain the optic regularly.
The OM1 includes Shake Awake technology, which helps conserve battery power by placing the optic into a low power state after a period of inactivity. Movement then reactivates the sight, allowing the selected reticle to become available without requiring the user to manually operate the optic.
Combined with the long rated battery life, this provides a convenient power management system for everyday use. Users can keep the optic configured and ready while allowing the automatic activation system to reduce unnecessary battery consumption during periods of inactivity.
The OM1 is constructed from 7075 T6 aluminum, giving the sight a rugged housing while keeping its weight low. The sight weighs approximately 0.96 ounces, helping maintain a lightweight overall pistol setup.
The optic is also described as having 5,000G shock resistance and having undergone live-fire and drop testing. Its construction is intended to resist moisture, debris, and impact, making it suitable for users who want a compact optic with a durable housing.
At just 0.96 ounces for the sight itself, the OM1 adds relatively little weight to the pistol. This can be useful on a Glock 19 Gen 6 because the optic can provide additional aiming capability without significantly increasing the weight of the setup.
Its low profile and compact construction also help maintain a relatively streamlined configuration. For users who prioritize lightweight equipment, the OM1 is an attractive alternative to heavier full size pistol optics.
The OM1 uses an RMSc/K footprint, so it does not directly match the Glock 19 Gen 6’s ORS mounting system. Unlike several of the other optics considered, however, ZEROHAWK includes MOS to RMSc and RMR to RMSc adapter plates with the OM1.

9) Triton Nautilus2 Micro Red Dot Sight
The Triton Nautilus2 Micro Red Dot Sight is a budget friendly pistol optic that combines a compact design, built in backup iron sights, a 3 MOA dot, Shake Awake technology, and a 50,000 hour battery life.
At approximately $72.99, it is considerably less expensive than many competing optics, while its CNC machined aluminum housing and IP64 rating provide useful durability for regular range and carry applications.
For the Glock 19 Gen 6, however, mounting compatibility needs to be considered carefully. The Nautilus2 uses a true RMSc/407K/507K footprint, while the Glock 19 Gen 6 uses the newer ORS mounting pattern. Therefore, it does not mount directly to the Gen 6 slide and requires a suitable Gen 6 ORS to RMSc adapter plate.
One of the more distinctive features of the Nautilus2 is its integrated rear backup iron sight. Rather than relying on a separate accessory that must be attached to the optic, the rear sight is CNC milled directly into the optic housing.
This provides an additional sighting option if the electronic reticle is unavailable. Integrating the rear sight into the housing also avoids adding another separate component to the optic. For users who appreciate redundancy in a pistol sighting system, this is a useful feature that differentiates the Nautilus2 from many compact red dots.
The Nautilus2 uses a RMSc/407K/507K footprint and can mount directly to appropriately cut slides such as those designed for RMSc optics. This makes it suitable for a range of compact pistol platforms that use this mounting standard.
The Glock 19 Gen 6 is different because its ORS mounting system does not use the standard RMSc pattern. Consequently, the Nautilus2 cannot be installed directly on the Gen 6 ORS slide. A dedicated Gen 6 ORS to RMSc adapter plate is required.
The Nautilus2 features a 3 MOA dot with 10 brightness settings. The dot provides a relatively simple aiming reference without adding additional reticle elements that could make the sight picture more complicated.
The brightness range allows the reticle to be adjusted for different ambient lighting conditions, including a daylight rated maximum intended to keep the dot visible against brighter backgrounds. This gives users greater control over reticle visibility rather than forcing them to rely on a single fixed illumination level.
The Nautilus2 is rated for up to 50,000 hours of battery life, depending on the operating mode and conditions. Together, the long rated battery life and automatic activation system reduce the frequency of battery maintenance.
The Nautilus2 is constructed from 6061 T6 aircraft grade aluminum, providing a lightweight housing designed to withstand regular handling and recoil. The optic is rated IP64, offering protection against dust ingress and water spray.
The housing is also described as being subjected to recoil simulation testing during production. While these manufacturer testing claims provide useful context, real world durability can vary depending on installation, ammunition, mounting hardware, and use.
The optic uses multi coated glass with anti reflective and hydrophobic coatings. These treatments are designed to reduce glare and help water resist accumulating on the viewing surface.
The combination of the coated lens and 3 MOA reticle is intended to provide a clear sight picture across changing lighting conditions. Keeping the lens clean is still important because any dirt, moisture, or residue on an exposed optic window can affect visibility.
Some users have reported better results after using blue threadlocker on the mounting hardware, but installation should follow the optic and adapter manufacturer’s specifications rather than relying solely on anecdotal recommendations.

Factors To Consider When Choosing The Best Red Dot Sight For Glock 19 gen 6
1. Mounting Footprint and Gen 6 ORS Compatibility
The first factor I would consider is mounting compatibility, because the Glock 19 Gen 6 uses the newer ORS optic mounting system rather than the mounting pattern found on many previous generation optics ready pistols. A red dot with an RMR or RMSc footprint may therefore require a dedicated Gen 6 ORS adapter plate instead of mounting directly to the slide.
Before buying, confirm both the optic footprint and the exact adapter required for the Gen 6 ORS cut. A direct fit is generally simpler, while an adapter based setup requires additional attention to plate compatibility, screw length, and installation.
2. Reticle Type and Size
The reticle has a major effect on how quickly and precisely the sight can be used. Common configurations include smaller dots such as 2 MOA or 3 MOA for a more precise aiming reference, larger dots such as 6 MOA for quicker visual acquisition, and circle dot combinations that provide both a prominent reference and a precise center point.
The best choice depends on your preference and intended use. A simple dot can provide an uncluttered sight picture, while a multi reticle system gives you more flexibility to select the presentation that works best for you.
3. Window Size and Optical Clarity
A red dot with a sufficiently large viewing window can make it easier to locate the reticle and maintain a broad sight picture during use. When comparing optics, look at both the physical window size and the quality of the lens.
Multi coated or aspherical lenses, anti reflective treatments, and hydrophobic coatings can help reduce glare, improve clarity, and keep moisture from interfering with the sight picture.
Parallax free operation and unlimited eye relief are also valuable characteristics because they make the optic easier to use without requiring a perfectly centered eye position.
4. Durability and Environmental Protection
Since a pistol mounted optic experiences repeated movement and recoil, durability should be an important consideration. Look for a housing made from a strong material such as 7075 T6 or 6061 T6 aluminum, along with appropriate shock and impact resistance.
Environmental protection is equally important. Waterproof or water resistant ratings can indicate how well an optic is designed to handle moisture, while enclosed emitter designs provide additional protection against dust, dirt, and debris reaching the emitter. The right level of protection depends on how and where the Glock 19 Gen 6 will be used.
5. Battery Life and Power Management
Battery life affects how often the optic needs maintenance and how much attention it requires between uses. Many modern pistol red dots offer thousands of hours of operation, with some rated for tens of thousands of hours depending on brightness and operating mode.
Features such as Shake Awake or motion activation can extend battery life by putting the optic into a sleep state when inactive and reactivating it when movement is detected. Solar backup systems can provide an additional power source on compatible models, while low battery indicators can provide useful warning before the battery needs replacement.
6. Battery Access and Maintenance
The way an optic’s battery is accessed is another practical consideration that is easy to overlook. Side loading and top loading battery compartments allow the battery to be replaced without removing the optic from the slide, which can help preserve the existing zero.
Bottom loading designs may require the optic to be removed before replacing the battery. Also consider whether the battery compartment is easy to access and whether the sight includes features that help retain small screws or other hardware during maintenance.
7. Backup Sighting and Reliability Features
Additional reliability features can provide useful redundancy if the electronic aiming system becomes unavailable. Some optics incorporate backup iron sights directly into the housing, while others are designed to work alongside separate backup sights.
Automatic activation, reticle memory, brightness lockout, and low battery warnings can also improve everyday practicality. When choosing an optic, consider which of these features genuinely benefit your intended use rather than paying extra for functions you are unlikely to use.
8. Price, Warranty, and Overall Value
Finally, consider the total value rather than simply the purchase price. A less expensive optic may become more costly if it requires a separate adapter, additional mounting hardware, or other accessories for the Glock 19 Gen 6. Compare the optic’s construction, features, battery system, mounting requirements, and warranty against its price.
A strong warranty can also provide additional confidence for long term ownership. The best choice is ultimately the optic that gives you the combination of compatibility, reliability, features, and durability you need without paying for unnecessary extras.

Advantages Of Using A Red Dot On Glock 19 Gen 6
1. Faster Target Acquisition
A red dot can make it easier to acquire the aiming point quickly because you do not have to align a front and rear sight in the traditional way. Once the dot is visible, you can place it on the intended target while maintaining a broader view of your surroundings.
This can make the sighting process more intuitive, particularly for shooters who become accustomed to presenting the pistol and locating the illuminated dot.
2. Improved Aiming Precision
A red dot provides a clearly defined aiming reference that can make precise shot placement easier. Smaller reticles, such as 2 MOA or 3 MOA dots, provide a relatively fine aiming point, while larger dots can offer faster visual acquisition.
With the appropriate brightness and reticle configuration, a red dot can provide a consistent reference that is easier to distinguish than conventional iron sight alignment.
3. Better Visibility in Different Lighting Conditions
Traditional iron sights can become harder to distinguish as lighting conditions change, whereas an illuminated red dot can remain highly visible when properly adjusted.
Modern optics often provide multiple brightness levels, allowing the reticle to be adjusted for bright daylight or darker environments. Some models also offer automatic brightness adjustment, helping maintain a visible aiming point as ambient light changes.
4. Unlimited Eye Relief
Unlike magnified optics, a pistol red dot provides unlimited eye relief, meaning the shooter does not need to position the eye at a specific distance from the optic.
This allows greater flexibility in how the pistol is presented and viewed. Once the dot is visible, the shooter can use it as the aiming reference without having to establish a traditional front sight and rear sight alignment.
5. Wider Sight Picture
Many red dots provide a relatively large viewing window that allows the shooter to see more of the area around the reticle. This can make it easier to maintain visual awareness while using the optic rather than focusing entirely on a narrow sight alignment.
A larger window can also make it easier to locate the dot during presentation once the shooter has developed familiarity with the optic.
6. More Flexible Reticle Options
A red dot gives the Glock 19 Gen 6 owner the opportunity to select different reticle configurations according to personal preference. Some optics use a simple dot, while others offer combinations involving different dot sizes and circles.
This allows users to prioritize either a precise aiming reference or a more prominent reticle designed for quicker visual acquisition.
7. Reduced Dependence on Traditional Sight Alignment
With iron sights, the shooter must align the rear sight, front sight, and target correctly. A red dot simplifies the aiming process by providing a single illuminated reference that can be placed where the shot is intended to go.
This can reduce the visual complexity associated with traditional sight alignment and make the transition to aiming more straightforward after sufficient practice.
8. Easier Use With Both Eyes Open
A red dot is well suited to shooting with both eyes open, allowing the illuminated aiming point to be superimposed over the target while maintaining a wider field of view.
This can make the overall sight picture feel less restrictive than looking through traditional sights. With practice, this can help users maintain better visual awareness while still having a precise aiming reference.
Best Red Dot Sight For Glock 19 gen 6 FAQs
1. Can I mount any RMR or RMSc red dot directly to the Glock 19 Gen 6?
No. The Glock 19 Gen 6 uses the newer ORS mounting pattern, so an optic with an RMR or RMSc footprint will not necessarily mount directly to the factory slide. If the optic uses a different footprint, you will need the appropriate Gen 6 ORS adapter plate. Always verify the exact footprint, adapter, and mounting hardware before installation.
2. What reticle size is best for a Glock 19 Gen 6 red dot?
A 2 MOA or 3 MOA dot is a versatile choice if you want a relatively precise aiming point while retaining good visibility. A larger 6 MOA dot can be easier to see and acquire quickly, while a multi reticle system with a dot and circle provides additional flexibility. The best option ultimately depends on your visual preference, lighting conditions, and intended use.
3. Should I choose an open or enclosed red dot for the Glock 19 Gen 6?
An enclosed emitter can be preferable if environmental protection is a priority because the enclosed design helps shield the emitter from dust, dirt, moisture, and debris. An open reflex optic can provide a broad sight picture and compact profile, but its emitter is more exposed.
When choosing between them, consider the environments in which you expect to use the Glock 19 Gen 6, as well as the optic’s durability, battery life, and mounting requirements.
Conclusion
In conclusion, the best red dot sights for the Glock 19 Gen 6 combine clear optics, durable construction, useful reticle options, reliable battery performance, and practical features such as Shake Awake, enclosed emitters, and convenient battery access. What makes these optics especially appealing is their ability to provide a fast, clear aiming reference while maintaining a broad sight picture and flexible brightness control.
