Faxon’s Match Series pistol barrels for SIG P320 are machined 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. 

Why Faxon Pistol Barrels?

  • 4150 or 416-R Stainless - 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

    Excellent Barrel.

    I slapped one of the bad boys in a certain chassis made by a certain company in Utah, and it's sweet. I shoots lights out, period. No issues with reliability and I have been able to make consistent shots at 50 years. A worthy improvement to anyone with a Full Sized P320.

    Having purchased Faxon AR barrels in the past, and I swear by them. This was the first Faxon pistol barrel I purchased, and will not be my last. Quality, Accuracy, Looks are make my P320 sing like Etta James!

    Nice little barrel pretty accurate. Only reason I’m giving a 4 is because it didn’t mention anything about removing the chambered round indicator in the description.

    Shipping was extremely fast. Quality is excellent. Adds 1 “ to original barrel lengths. Longer barrel means more velocity as well as accuracy. Extremely pleased with this product. It looks great with the fluted flames as well.
