Built for Real-World Use

Faxon Duty Series pistol barrels are designed to exceed factory standards without sacrificing reliability. A SAAMI-spec 9mm chamber ensures broad ammunition compatibility, while tighter machining tolerances promote a more consistent lockup than OEM barrels. The result is improved accuracy potential with the dependability required for duty, carry, and training pistols.

Benefits

  • Enhanced durability: 4150 CMV steel and nitride treatment increase barrel life and surface hardness.
  • Smoother cycling: Salt bath nitride improves lubricity for reliable cycling.
  • Ammo flexibility: Conventional rifling supports jacketed, plated, coated, and cast lead bullets.
  • Improved consistency: Tighter-than-OEM tolerances deliver repeatable lockup.
  • No fitting required: Designed as a true drop-in replacement.
