Faxon Duty Series Threaded Barrel for M&P® Shield / Shield Plus 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.
Faxon Duty Series Barrels for M&P® Shield provide a quick and easy upgrade to your M&P® Shield handgun. These barrels are manufactured in our Cincinnati, Ohio facility from raw bar stock to provide premium accuracy, fit, and finish. Faxon M&P Shield barrels feature our signature "X" logo engraved on the top of the hood, with layered pocketing and caliber identification on the ejection port side. Both threaded and non-threaded versions feature straight fluting and are compatible with M&P Shield 1.0, 2.0, and Shield Plus with 3.1" barrels.
The Match Series Barrels for M&P® Shield are backed by Faxon's Lifetime Guarantee.
Fitment Note: Faxon Firearms M&P Shield barrels are not drop-in compatible with M&P Shield pistols that have a Loaded Chamber Indicator lever installed (such as the California compliant variation). If you have a pistol with the LCI lever installed (or are unsure if your pistol is drop-in compatible) please contact our Customer Service Team for more information: customerservice@faxonfirearms.com
