FAXON DUTY SERIES BARREL FOR P320 COMPACT 9MM
FaxonFaxon Duty Series Barrel for SIG® P320 Compact 9mm Nitride
Faxon’s Duty Series pistol barrels for SIG® P320 are machined in-house from stress-relieved 4150 CMV 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.

Crafted from stress-relieved 4150 CMV steel with a full salt bath nitride finish inside and out, this barrel provides maximum corrosion resistance, wear protection, and lubricity for hard-use duty, range, or defensive applications.
