Faxon Firearms Duty Series 9mm Luger 3.1" Black Nitride Drop-In Pistol Barrel - Fits M&P Shield/Shield Plus

Upgrade your concealed-carry pistol with the Faxon Firearms Duty Series drop-in 3.1" pistol barrel, chambered in 9mm Luger and engineered specifically for the Smith & Wesson M&P Shield and M&P Shield Plus. Machined 100% in-house from stress-relieved 4150 CMV steel, this barrel is built for hard-use reliability and long service life in everyday carry and duty use.

The Duty Series features a complete salt bath nitride treatment inside and out, delivering maximum corrosion and wear resistance with a tough black nitride finish. The 1:10 twist rate is optimized to stabilize a broad range of 9mm bullet weights, and the drop-in design installs in minutes without gunsmithing or fitting. Designed as a direct-fit replacement for the factory M&P Shield and Shield Plus barrel, the Faxon Duty Series is the ideal upgrade for shooters seeking enhanced accuracy, durability, and consistency from their carry pistol.

The barrel ships with no sights installed, allowing you to run your existing factory sights or transfer them directly from the OEM barrel. Whether you are replacing a worn factory barrel or building out a custom Shield-platform pistol, this Faxon Firearms Duty Series barrel delivers the fit, finish, and performance expected from a premium American-made upgrade.
