The G45’s crossover configuration pairs a compact-length slide with a full-size frame, delivering duty-ready handling in a balanced package. Its black nDLC slide includes forward and rear serrations and a factory MOS optics cut with the cover plate installed. Markings include "MADE IN AUSTRIA GLOCK, INC., SMYRNA, GA."
The 4.02 in Glock Marksman Barrel (GMB) provides enhanced accuracy potential, and the fixed polymer sight set is straightforward and durable, with a white-dot front and white-outline rear. The pistol retains the Gen5 design language throughout.
Controls are set up for versatility with ambidextrous slide-stop levers and a reversible magazine release. A flared magwell speeds reloads, while Gen5 texturing offers a secure grip. The dust cover includes an integrated accessory rail for mounting compatible lights or lasers.
Capacity is 17+1 with included Glock-branded double-stack magazines. This example shows matching serial numbers on the slide, barrel, and frame, and comes with the Glock factory hard case.
