Glock 43X 9mm Pistol, 3.92-inch Threaded Barrel, Suppressor Sights

The Glock 43X is a slimline 9mm pistol (brand part no. UX4350204FRN) built around a 3.92-inch threaded barrel for this configuration. Glock builds the 43X on its compact Slimline frame with a slim mounting rail, giving it the same compact grip length and built-in beavertail as the larger G48 for a comfortably balanced, versatile grip. This build’s slide is equipped with a Hush Puppy slide lock, a system that reduces mechanical noise during suppressed operation to maximize stealth and efficiency, and it’s paired with suppressor-height sights that co-witness through a can. It’s built for shooters who want a slim, easily concealed 9mm that’s still fully set up for suppressed use.
