Glock G45 Gen5 9mm Luger Crossover Pistol, 4.02 in GMB Barrel, Black nDLC, 17+1, 3 Mags
The Glock G45 Gen5 pairs a G19-length slide with a full-size G17 grip for a balanced, duty-ready crossover in 9mm Luger. This Austrian-made example features the Gen5 Glock Marksman Barrel, a black nDLC slide finish with front and rear serrations, and ambidextrous slide stop levers. It ships with three 17-round magazines, two modular backstraps, and a Glock factory case with matching serial label, with matching serial numbers on the frame, slide, and barrel.
The slide is the non-MOS configuration with an unmilled top and no optic cut. Fixed polymer sights are installed, with a front dot and a 6.1-height rear notch. The integral Glock accessory rail, slightly flared magwell, and Safe Action system round out a straightforward, duty-focused build.
