Faxon Firearms Duty Series 9mm Luger 4.02" 1:10 Twist Non-Threaded Glock 19 Barrel - Black Nitride

The Faxon Firearms Duty Series pistol barrel is a true drop-in replacement for the Glock 19 family, fitting the G19, G19X, and G45 across Gen 2 through Gen 5, and is chambered in 9mm Luger. This non-threaded variant keeps the slide profile clean, making it an easy upgrade or direct replacement for a worn factory barrel on duty, carry, or range pistols.

Faxon machines each barrel from stress-relieved 4150 CMV steel, then treats the surface with a black salt bath nitride finish for excellent surface hardness, wear resistance, and corrosion protection. The bore is cut with conventional rifling at a 1:10 twist rate for consistent accuracy with a wide range of factory and duty-grade ammunition.

Profiled as a true drop-in barrel at 4.02" overall length, the Duty Series is made in the USA and built to the standard shooters expect from a duty-grade component - whether you are running stock, light, or hot-loaded defensive 9mm.
