Faxon Pistol Barrels for Glock® 17 / G17 are machined 100% in-house from stress relieved 4150 CMV steel (Duty Series) or 416-R stainless steel (Match Series). Then, our barrels are given a black Nitride or PVD coating to increase lubricity, resistance to surface wear, and barrel life. We conventionally rifle all our pistol barrels to allow for a wider range of compatible ammunition, including cast lead. Don’t worry about gunsmithing, as these barrels easily drop into factory-spec slides. We ensure a consistent tighter lockup than OEM with better-than-factory tolerances.
