7 Best Red Dots for Glock 19
In this guide, we review the 7 Best Red Dots for Glock 19, covering their features, advantages, limitations, and factors to consider before purchasing. Let us look at it.
1. Holosun HS507C X2 2 MOA Dot & 32 MOA Circle Red Dot Sight
The Holosun HS507C X2 2 MOA Dot & 32 MOA Circle Red Dot Sight is an excellent all-around option for Glock 19 owners who want a versatile pistol optic. Its combination of a compact design, multiple reticle options, and RMR footprint makes it a popular choice for a variety of shooting applications. It is particularly appealing to users who want flexibility without moving to a larger optic.
One of the main advantages of the HS507C X2 is its multiple reticle system. It offers a 2 MOA dot, a 32 MOA circle, or a combination of both. This allows users to choose a reticle that suits their preferences and shooting conditions. The circle-dot reticle can provide a prominent aiming reference, while the smaller dot offers a more precise aiming point.
The sight also features Solar Failsafe and Shake Awake technology. Solar Failsafe can help maintain illumination when sufficient ambient light is available, while Shake Awake activates the optic when movement is detected.

The HS507C X2 uses the Trijicon RMR footprint, which is widely supported by pistol mounting systems. On a Glock 19 MOS, it can be installed using a compatible RMR adapter plate. Owners of standard Glock 19 slides will need an appropriate optic cut or mounting solution.
For users seeking a balance of features, versatility, and price, the HS507C X2 is a strong choice. It may not have the fully enclosed design of the ACRO P-2, but its reticle flexibility and established mounting footprint make it a practical option for many Glock 19 configurations.

Its 3.25 MOA reticle provides a useful balance between a visible aiming point and a compact dot size. The reticle is suitable for users who prefer a simple aiming reference without the additional circle found on some multi-reticle optics. The adjustable LED model allows brightness changes according to lighting conditions.
The RMR Type 2 uses the Trijicon RMR footprint, which is compatible with many Glock 19 MOS adapter plates. This makes it relatively straightforward to install on an optics-ready Glock 19 when the correct plate is selected. A standard Glock 19 slide requires an appropriate optic cut or mounting solution.
Another advantage is its compact housing. The RMR does not require the larger enclosed body used by some newer optics, which can make it easier to fit into certain holster and equipment configurations. However, users should still confirm that their chosen holster accommodates the specific optic.
The Trijicon RMR Type 2 is best suited to Glock 19 owners who value a straightforward, established optic design. Its higher price may be justified for those who prioritize a rugged housing and a widely supported footprint.
Features
- 3.25 MOA red dot.
- Adjustable LED illumination.
- Trijicon RMR footprint.
- Rugged housing.
- Compact pistol optic format.
Pros
- Proven design.
- Durable housing.
- Widely supported footprint.
- Simple aiming reference.
Cons
- Higher price than many alternatives.
3. Aimpoint ACRO P-2 3.5 MOA Red Dot Reflex Sight
The Aimpoint ACRO P-2 3.5 MOA Red Dot Reflex Sight is an enclosed-emitter optic designed for users who want a sealed sight housing. Its enclosed design helps protect the emitter from dust, dirt, and other environmental contamination. This makes it an appealing option for Glock 19 owners who prefer an enclosed pistol optic.
The ACRO P-2 uses a 3.5 MOA red dot, which offers a simple aiming point without a circle reticle. The dot size is suitable for users who want a balance between visibility and precision. Its enclosed housing also gives the optic a distinctive appearance compared with traditional open-emitter sights.

Glock 19 MOS owners need an appropriate ACRO adapter plate, while standard slides require a compatible optic cut or mounting system.
The enclosed design can be especially useful in environments where the optic may encounter dust or debris. However, the larger housing can affect the overall profile of the pistol and may require a holster designed specifically for an enclosed optic.
For Glock 19 owners who want an enclosed-emitter sight from an established optics manufacturer, the ACRO P-2 is a strong choice. Its main disadvantages are the higher cost and the need to confirm mounting and holster compatibility.
Features
- 3.5 MOA red dot.

The EPS Carry is a good option for Glock 19 owners who want a compact enclosed-emitter optic. However, its smaller window and different mounting footprint mean that it should be selected carefully based on the user’s slide and preferred sight picture.
Features
- 2 MOA red dot.
- Enclosed emitter.
- Holosun K footprint.
- Compact housing.
- Adjustable brightness.
Pros
- Compact enclosed design.

The large window is the SRO’s most distinctive feature, but its open-emitter design means the emitter is not enclosed. Users should also confirm that their holster and other equipment are compatible with the SRO’s larger housing.
The Trijicon SRO is best suited to Glock 19 owners who value a large viewing window and a small dot. Its higher cost and open-emitter design may make it less attractive to users who prioritize a compact or fully enclosed optic.
Features
- 2.5 MOA red dot.
- Large circular viewing window.
- Trijicon RMR footprint.
- Adjustable illumination.
- Open-emitter design.
Pros
- Large sight window.

The Vortex Defender-CCW 3 MOA Red Dot Sight is a compact pistol optic designed for users who want a practical red dot without moving into the highest price range. Its smaller profile makes it worth considering for Glock 19 owners who want a relatively unobtrusive sight.
The 3 MOA dot offers a straightforward aiming reference. It is a useful size for users who prefer a simple reticle rather than a circle-dot arrangement. The optic’s compact format can also be attractive to users who want to maintain a relatively streamlined pistol setup.
The Defender-CCW is available in a compact footprint family, so compatibility should be checked carefully against the exact model and mounting system. Glock 19 MOS owners should confirm the correct adapter plate, while standard slides need an appropriate optic cut or mounting solution.
