Glock 17 Gen6 COA

The G17 Gen6 COA is the factory-optic version of Glock's full-size duty pistol, shipped with an Aimpoint COA enclosed red dot installed at the factory on an A-CUT slide. It keeps the 17+1 capacity and 4.49-inch barrel of the standard G17 Gen6 while fixing the optic mount: the COA seats directly on the steel instead of riding the polymer Optic Ready System plates.

The A-CUT interface machines a full-length dovetail into the slide and locks the COA in with a front hook and a rear wedge, transferring recoil into the dovetail wall rather than the mounting screws. That removes the zero-shift failure mode the standard Gen6 ORS is known for. The COA runs a 3.5 MOA dot, a sealed enclosed emitter that resists rain and debris, four night-vision settings, and a CR2032 rated past 50,000 hours. Metal co-witness backup sights replace the polymer irons on the rest of the line.

The package ships with three 17-round magazines and the full Gen6 frame updates: RTF6 dual-pattern texture, integrated palm swell, fixed beavertail, undercut trigger guard, and a flat-faced trigger. The longer 4.49-inch barrel and sight radius make it the most shootable COA Glock. The Gen6 trigger housing is not interchangeable with Gen5, so confirm Gen6 fitment before buying aftermarket triggers.
