This 9mm drop-in replacement barrel fits the Glock 17 across Gen 3, Gen 4, and Gen 5. Machined from 4150 chrome-moly steel and finished in Black Nitride for surface hardness, corrosion resistance, and reduced fouling pickup.
Factory-spec chamber and lug geometry — no gunsmithing required. Conventional rifling means the barrel runs cast lead, plated, and jacketed 9mm without restriction. A solid replacement when the factory barrel is worn or you want a clean upgrade path before adding an optic-cut slide.
Specs:
Confirm your slide is cut to factory Glock 17 spec before install. Run 50–100 rounds to verify extraction and feeding with your carry load before relying on it for duty use.
