The GLOCK G45 Gen 6 9mm Optic Ready is a crossover pistol combining a compact slide with a full-size frame — built for duty, competition, and everyday carry with GLOCK's latest ergonomic refinements and a factory optic-ready slide.
The G45 Gen 6 pairs a compact 4.02-inch GLOCK Marksman Barrel (GMB) with a full-size frame, delivering a reduced muzzle profile and faster target acquisition without sacrificing magazine capacity. Chambered in 9mm Luger with 17+1 rounds and an optic-ready slide for direct mounting of micro red dot optics, it bridges the gap between the compact G19 and full-size G17.
The Gen 6 frame incorporates a palm swell, thumb rest, and enlarged beavertail for a natural, repeatable grip. A flat-faced trigger provides uniform finger placement shot to shot. The SAFE ACTION® System delivers three passive, independently operating mechanical safeties. Three 17-round magazines included.
