Glock 19 threaded 9mm barrel — drop-in replacement for the Glock 19 across Gen 1 through Gen 5. Machined from 4150 chrome-moly steel and finished in salt-bath black nitride for surface hardness and corrosion resistance. The 1/2x28 TPI muzzle mates cleanly with the 3CR 9mm Micro Compensator, most 9mm pistol comps, and direct-thread pistol-caliber suppressors.
Factory-spec lockup — no gunsmithing required. Conventional rifling runs cast lead, plated, and jacketed 9mm loads.
Specs:
Micro Comp pairing: Slots directly onto the 3CR 9mm Micro Compensator for a Gen-agnostic G19 comp build. Suppressor users should keep the thread protector snug when running unsuppressed — G19 recoil spring pressure will walk a loose protector off after a few magazines.
Verify your slide is cut to factory Glock 19 spec before install. Run 50–100 rounds before adding a compensator or suppressor so you confirm the barrel runs cleanly on its own first. Comp and suppressor compatibility is shooter-installed — verify timing on any muzzle device.
