The SilencerCo Threaded Barrel for the Glock 19 (brand part number AC862) is a direct-fit 9mm replacement barrel built for shooters adding a pistol suppressor to their compact carry gun. Every pistol suppressor needs a threaded host barrel, and SilencerCo machines this one from 416R stainless steel and finishes it in black nitride to hold up under harsh use. The barrel measures 4.50 inches with a right-hand 1:10-inch twist and is cut 1/2×28 to accept standard 9mm suppressor mounts. A piston is required separately to complete a suppressor setup.
