Faxon Duty Series Barrel for SIG® P365 9mm Nitride

Faxon’s Match Series pistol barrels for SIG® P365 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.

The Faxon Duty Series Barrel for SIG® P365 is engineered for rugged reliability and consistent performance in a compact, everyday carry platform. Crafted from stress-relieved 4150 CMV steel with a full black nitride finish inside and out, this barrel provides superior corrosion resistance, wear protection, and lubricity for hard-use defensive or range applications.
