Faxon's Match Series pistol barrels for GlockA(R) G43 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.
