Faxon Duty Series Threaded Barrel for G34 Gen 1-4 9mm Nitride

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.

Key Benefits

  • 4150 CMV Steel: Only the best steels for durability, longevity, and accuracy.
  • 9mm SAAMI Chambers: Superior accuracy with complete SAAMI compatibility & boring reliability.
  • Tighter Tolerances: Drop-in, yet better fitment and lock-up.
  • Conventional Rifling: Fully compatible with cast bullets.
  • 11 Degree Target Crown: Consistent bullet release for enhanced precision.
