At Faxon, we machine all our pistol barrels for Glock® right here in Cincinnati, Ohio from stress- relieved 4150 CMV steel (Duty Series) or 416-R stainless steel (Match Series). We conventionally rifle all our barrels, which allows for the use of a wider range of ammunition, including cast lead. These barrels are coated with either black Nitride or PVD to improve barrel life, lubricity, and resistance to surface wear. There is no gunsmithing required as our pistol barrels drop into factory-spec slides. Better-than-factory tolerances ensure a consistent, tighter lockup than OEM. We carry barrels for G17, G19, G34, and G43/43X.
