Faxon s Duty Series pistol barrels for Glock 34 are machined in-house from stress-relieved 4150 CMV Steel. These barrels are then given a black Nitride 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 G34 (Gen 1-4) brings rugged duty-grade reliability and suppressor-ready capability to the competition-size platform. Featuring a threaded muzzle and full salt bath nitride finish inside and out, this barrel is perfect for competitive shooting, duty use, or long-slide suppressed builds.
