FAXON DUTY SERIES THREADED BARREL FOR M&P® FULL SIZE GEN 1/2 9MM
Faxon Duty Series Threaded Barrel for M&P® Full Size Gen 1/2 9mm Nitride
Faxon’s Duty Series pistol barrels for Smith and Wesson/M&P are machined 100% in-house from stress-relieved 4150 CMV steel. These barrels are then given a black Nitride 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 Threaded Barrel for M&P® Full Size Gen 1/2 delivers rugged, reliable performance with suppressor-ready versatility in a full-size drop-in upgrade. Crafted from stress-relieved 4150 CMV steel with a full salt bath nitride finish inside and out for maximum corrosion resistance, wear protection, and lubricity, this threaded barrel is built for hard-use duty, range, competition, or defensive applications where dependability and accessory compatibility are essential.
