Faxon Match Series P320 Barrel
Faxon's Match Series barrels represent a significant upgrade over factory Sig P320 components. Each barrel is machined in-house from stress-relieved 416-R stainless steel, a material chosen for its dimensional stability and longevity.

Superior Design
The salt bath nitride coating increases lubricity, extends barrel life, and provides excellent resistance to surface wear and corrosion. Unlike some aftermarket barrels, Faxon's conventional rifling accommodates a wider range of ammunition, including cast lead rounds—a consideration for shooters who reload or use budget ammunition.
Installation & Accuracy
These barrels drop into factory-spec P320 Full Size slides without gunsmithing. Better-than-factory tolerances ensure consistent, tighter lockup than original equipment, translating to improved accuracy and reliability. The flame-fluted design reduces weight while maintaining structural integrity.
Note: Not compatible with M17 or X-Series P320 variants.
