Best Red Dot For Glock 17

Holosun 507C - Best Overall

This sight fits the RMR footprint, so you don't need a special adapter. If you own a Glock 17 MOS, use the included Trijicon RMR plate or any other optic plate. The big buttons are a highlight. They're easy to adjust with large fingers, day or night.

The battery lasts up to 50,000 hours. If it runs out, there's a solar panel to power the optic. You can change the battery easily from a side tray without taking off the sight. Some believe the sight turns off when the battery dies, but it doesn't. The solar backup keeps the optic working. Right now, this sight is at its best price, making it a top choice similar to a Trijicon RMR.

Holosun 509T - Best Weatherproof

The Holosun 509T for Glock 17 users can handle any weather. It keeps out dirt, water, and other things you don't want interfering with the emitter screen. You can easily put this strong optic on any platform that has an RMR footprint, but an adapter plate is needed to mount the 509T on the Glock 17. Even though some people might not know, its design stops any dirt from getting inside.

The 509T fits tightly on the index posts. Its recoil lugs keep the optic steady and in place. If you know the Holosun 507C, the side battery door is easy to use. You can change the battery fast without taking off the sight.

Trijicon SRO - Largest Sight Window

We chose the Trijicon SRO 5 MOA version for Glock 17, because it's perfect for competitive shooting and getting on target quickly especially with a longer sight radius. The SRO uses the same RMR base and has an impressive battery life that last more than 4 years, 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 right from the top without sight removal.

Trijicon RMR Type 2 - Best Durability

The Trijicon RMR Type 2 is the best RMR for Glock 17 shooters 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.

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 17 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. This is similar to the motion sensor in the Holosun 507C.
