Faxon s Match Series pistol barrels for Glock G17 are machined 100% in-house from stress-relieved 416-R stainless steel. These barrels are then given a black Nitride or PVD coating to increase lubricity, barrel life, and resistance to surface wear. All barrels are conventionally rifled to allow a wider range of ammunition to be used, including cast lead. The barrels drop into factory-spec slides with no gunsmithing required. Better-than-factory tolerances ensure a consistent, tighter lockup than OEM. The Faxon Duty Series Threaded Barrel for Glock G17 Gen 5 delivers rugged, hard-use reliability with suppressor-ready versatility in a full-size drop-in upgrade. Built from stress-relieved 416-R stainless steel with a full salt bath nitride finish inside and out for maximum corrosion resistance and durability, this barrel is engineered for demanding duty, competition, training, or defensive applications where dependability and accessory compatibility matter most.
