There are hundreds of red dot sights on the market, but Aimpoint’s collaboration with Glock on the new Aimpoint COA isn’t just another repetitious optics launch. The COA, which is only available as a package deal on Glock pistols, is the culmination of the most desirable features in a pistol optic . It has an enclosed emitter, sits low in the slide, and features a rock-solid mounting system. We’ve had the chance to test the COA on two different pistols over the past months, here’s why we love it.

To understand what we like about the Aimpoint COA, it helps to consider other red dots. Look at where past and current models fall short.
