The Trijicon RMR is one of the most physically durable red dots on the market. It doesn't really like water, but if you plan to use your red dot to break big rocks into smaller rocks in the desert, this is your best option. And putting it on a Glock is seriously an obvious choice. This red dot is small and low enough to fit between the rear dovetail and the internal safety plunger, and cowitness neatly with standard Trijicon suppressor height sights.
Speaking of, cowitnessing or other sight fitment is not guarantied with other options due to the almost infinite variety of Glock sights. If you are concerned about cowitnessing or fit, you can send in the sights with your slide, and we can render everything up before we ever start cutting. This service is an additional fee, but especially for a duty pistol where you NEED it to cowitness, it's probably worth while.
The cost includes all tear down and reassembly, including installing new sights if you included them, and it also includes a single color Cerakote of your choice on the slide. If you want a custom color or pattern, please email or call before placing your order.
