The Griffin Armament Barrel with Compensator (brand part number GAG17G4TB) is a 9mm replacement barrel built for the Glock 17, Gen3 and Gen4, that ships with an integrated compensator installed. Griffin Armament machines its ATM-series barrels for match-grade fitment and durability. Adding a compensator directly to the barrel helps manage muzzle flip and felt recoil on a full-size 9mm pistol, improving control during rapid strings of fire. At roughly 5 inches overall with the compensator installed, this barrel is a direct-fit upgrade for Glock 17 Gen3/4 owners looking for both accuracy and recoil control in one package.
