The SilencerCo Threaded Barrel for the Glock 34 (brand part number AC860) is a direct-fit 9mm replacement barrel built for Gen 1-4 Glock 34 pistols (not Gen 5), for shooters adding a pistol suppressor to their competition-length 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 5.80 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.
