9mm threaded drop-in barrel for the Glock 19 Gen 1-3. Slides into factory and aftermarket Glock 19 slides without fitting work. Threaded 1/2x28 muzzle pairs with standard 9mm compensators, thread protectors, and suppressors. Gen 4 and Gen 5 owners can run this barrel with a Gen 3 recoil rod assembly and adapter.
Finished with a multi-color oil slick PVD coating over 416R stainless steel — every barrel is unique in coloration. The PVD will wear over time on metal-to-metal contact points; that's normal and adds character.
Lubricate the inside top of the slide on first install — tolerances run tight on the initial 100-round break-in. Verify your recoil rod assembly is set up for Gen 3 timing before running this barrel in a Gen 4 or Gen 5 frame. See our slide break-in guide for the full procedure.
