9mm threaded drop-in barrel for the Glock 19 across Gen 1 through Gen 5. Machined from 4150 chrome-moly steel and finished in Black Nitride for surface hardness and corrosion resistance. The 1/2x28 TPI muzzle thread pairs cleanly with the 3CR 9mm Micro Compensator, standard 9mm pistol comps, and most direct-thread suppressors.

Factory-spec lockup — no gunsmithing required. Conventional rifling runs cast lead, plated, and jacketed 9mm. Ships with thread protector installed.

Verify your slide is cut to factory Glock 19 spec before install. Run 50–100 rounds before adding a compensator or suppressor so you can confirm the barrel runs cleanly on its own first. Comp/suppressor compatibility is shooter-installed — verify timing on any muzzle device.
