Griffin Armament Threaded Glock Pistol Barrels

Griffin Armament Threaded Glock Pistol Barrels are built for shooters who want match-grade fit, suppressor support, and reliable function from a concealed-carry-focused pistol setup. Each ATM, or Advanced Threaded Match, barrel is billet machined from 416R chromium stainless steel and finished in Black Nitride for surface hardness, wear resistance, and corrosion resistance.

Critical machining is completed in a single work holding, allowing the breech, slide interface, and locking lug dimensions to maintain an exact geometrical relationship. The chambers are honed, polished, and cut to 9mm SAAMI specifications to support reliable function across a broad range of ammunition, from training to duty loads.

Each barrel includes a 1/2x28 threaded muzzle for suppressor or accessory support, a target crowned muzzle, broach cut rifling, and a 1:10 twist rate. For a limited time, each barrel also includes Griffin’s patent pending Micro Carry Comp, designed to provide a low-profile carry signature, broad holster compatibility, and noticeable recoil reduction without changing the overall handling of the firearm.
