GLOCK 45 MOS 9mm Pistol

The GLOCK 45 MOS combines a compact-length slide with a full-size frame, creating the crossover configuration that distinguishes the G45 from traditional compact and full-size GLOCK pistols. Chambered in 9x19mm, it incorporates Gen5 design features along with an optic-ready slide for compatible reflex sights.

GLOCK’s Modular Optic System uses a factory-prepared slide that allows compatible reflex optics to be mounted using the appropriate mounting components. This gives users the option to configure the pistol with an optic without permanently modifying the slide.

The G45 MOS also includes a 4.02-inch GLOCK Marksman Barrel, front slide serrations, a flared magazine well, enhanced frame texture, and the Modular Backstrap System. A reversible magazine catch and ambidextrous slide stop lever make the controls adaptable for right- or left-handed use.

At 7.44 inches long and approximately 24.52 ounces with an empty magazine, the G45 MOS retains the shorter slide dimensions of a compact GLOCK while providing the grip height and standard 17-round capacity associated with a full-size frame. The result is a Gen5 configuration suited to range use, training, and shooters who prefer full-size grip dimensions without a full-length slide.
