As we reported earlier, Glock and Aimpoint teamed up to create a new pistol red dot sight called COA and a new pistol reflex sight mounting footprint called A-CUT. The COA is a very light and compact enclosed emitter red dot sight and the A-CUT is a pretty simple and unique mounting system that according to Aimpoint allows the COA to be mounted deeper and more firmly into the slide. At SHOT Show 2025, we had a chance to take a look at the new Aimpoint COA sight and shoot Glock pistols equipped with this sight.
