Description

Faxon’s Match Series pistol threaded barrels for SIG Sauer® P320 are machined 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 broader range of ammunition, including cast lead. The barrels drop into many factory-spec slides with no fitting required. These barrels do not fit SIG Pro-Cut slides.

These match series barrels feature better-than-factory tolerances ensuring a consistent, tighter lockup than OEM.
