Back in December when Glock announced the new Generation 6 Glock 17, 19 and 45 one of the questions many asked online is will there be a GEN 6 COA?The COA, if you’re not familiar, is a collaboration between Glock and AIMPOINT which was launched at SHOT Show 2025.The COA concept combines a new enclosed emitter pistol red dot sight (the COA) and a new pistol reflex sight mounting footprint called the A-CUT.The A-CUT allows the COA to be mounted deeper and more firmly into the slide.
