The Holosun EPS Carry is designed to withstand all types of weather for Glock 19 users, ensuring it's protected from dirt, water, and other unwanted elements. This robust optic can be easily mounted on any platform with an RMR footprint. Unlike what some might think, its closed emitter design ensures that no debris can enter the optic.

We chose the Trijicon SRO 5 MOA version for Glock 19, because it's perfect for competitive shooting and getting on target quickly. The SRO uses the same RMR base and has an impressive battery life, though it's not meant for heavy-duty use in the context of direct impact on the lens repeatedly.

With this sight, you can spot the dot faster and more reliably, even if your pistol draw is a bit off. It also offers automatic brightness settings. You can pick a brightness level and lock it, or let the surrounding light decide for you. A great feature is the top battery compartment.

You can change the battery from the top without removing the sight or resetting it. After each shot, you can spot the dot again quickly, so you don't waste time searching for it. Some people think you need to remove the sight to change the battery, With the SRO, battery changes are hassle-free.

The Trijicon RMR Type 2 is the best RMR for Glock 19 users for many years. It's designed with a better battery grip, ensuring the dot stays on without any hitches. This red dot sight is made from the super tough 7075 T6 aluminum material, so it can handle drops and other rough handling without breaking.

It's perfect for concealed carry because of its Lock Mode, which sets the brightness automatically. Plus, it's night vision friendly with two special modes for using with night vision goggles. One of the best features is its long-lasting battery, which can work up to four years. However, it's a good idea to change the battery every year. The Trijicon RMR provides different red dot sizes, ranging from 1 MOA to 6.5 MOA.

For those with astigmatism, the 6.5 MOA dot is the best pick. Some people might think bigger dots are not precise, but in reality, the 6.5 MOA dot ensures faster target acquisition and a rounder dot.


  • The most durable on the market
  • Lens shape divert impact stress away from the glass
  • Very long battery life

Swampfox Justice - Best For The Money

Most red dot sights differ from the Swampfox Justice red dot sight. The Swampfox Justice fits perfectly on any Glock 19 RMR optic cut slide because it uses the same RMR footprint. Its unique tapered sight design (1 X 27) makes the field of view seem larger, helping users quickly lock onto targets.

When comparing the Swampfox Liberty and Justice, the Justice offers a clear sight picture. It provides unlimited eye relief, ensuring quick target spotting, just like other red dot sights. Its skeletonized body is not only lightweight but also compatible with most optic-ready holsters, including the ALS series duty holsters. One standout feature is its "Shake Awake" technology.
