The SilencerCo 9mm Threaded Barrel (brand part number AC5335) is a direct-fit replacement barrel for Glock-pattern pistols, built for shooters adding a pistol suppressor to their gun. Every pistol suppressor needs a threaded host barrel, and SilencerCo machines this one from 416R stainless steel and finishes it in black nitride, though some models ship in bare stainless, for durability. The barrel measures 5 inches with a 1:10-inch right-hand twist and is cut 1/2×28 to accept standard 9mm suppressor mounts. A piston is required separately to complete a suppressor setup.
