The SilencerCo Glock 19 threaded barrel in 9mm (brand part no. AC862) is a direct-fit replacement barrel from SilencerCo that gives the Glock 19 the muzzle threads a pistol suppressor requires. SilencerCo makes it from 416R stainless steel and finishes it in black nitride, a build meant to hold up under harsh conditions. It is cut 1/2×28 and ships with a thread protector to cover the threads when no suppressor or muzzle device is mounted. For a Glock 19 owner adding a suppressor, it is the host barrel the setup starts with.
