Introduced in 2018 and quickly adopted by numerous U.S. law-enforcement agencies, the G45’s crossover design offers the sight radius and balance many shooters prefer. The full-size grip ensures secure control, while the compact slide promotes fast presentation from holsters.
This pistol carries Austrian proof marks and matching serial numbers on the slide, barrel, and frame, confirming factory original components. The black nDLC finish provides enhanced hardness and corrosion resistance across both slide and barrel.
The 4.02-inch Glock Marksman Barrel uses polygonal rifling for consistent velocities and simplified maintenance. A reversible magazine release and ambidextrous slide-stop lever support left- or right-handed operation without modification.
With three 17-round magazines, modular backstraps, and the complete MOS adapter kit included, the buyer can tailor grip size and immediately mount a preferred optic, maximizing the pistol’s versatility straight out of the case.
