Faxon Duty Series 4150 CMV Black Nitride Non-Threaded 9mm Barrel for Glock^® 19 Gen 2–5

The Faxon Duty Series 4150 CMV Non-Threaded 9mm Barrel for Glock^® 19 Gen 2–5 is engineered to deliver dependable performance, increased accuracy, and long-term durability in a direct drop-in upgrade for your Glock^® platform. Whether you’re replacing a worn-out OEM barrel or upgrading for training, carry, or competition, this barrel reflects the rugged reliability and precision machining that defines Faxon’s Duty Series.

Made from 4150 CMV steel, this barrel is stress-relieved and QPQ nitride treated both inside and out. The result is exceptional surface hardness, corrosion resistance, and an extended barrel life, even under high-volume use. Designed to work seamlessly with Glock^® 19 Gen 2 through Gen 5 pistols, this non-threaded model maintains a flush fit with the slide for a clean factory-style appearance while still delivering premium aftermarket performance.

The 1:10 twist rate is optimized for stabilizing common 9mm loads, offering consistent performance across defensive, target, and training ammunition. Conventional rifling allows safe use of all bullet types, including cast lead—making this barrel a versatile choice for reloaders and high-volume shooters. The 11-degree target crown enhances precision by ensuring consistent gas dispersion at the muzzle.

Built with tighter tolerances than OEM barrels, this model improves lockup with the slide, contributing to greater mechanical accuracy. It installs without modification and is compatible with all Glock^® 19 internal components and factory recoil systems. As a non-threaded option, it’s ideal for users who do not require suppressors or compensators and prefer a streamlined design for everyday carry or duty use.

Faxon Firearms is known for precision, quality, and innovation—and this Duty Series barrel upholds that legacy. For shooters demanding consistent reliability without the need for custom fitting, it’s a smart and straightforward performance upgrade.
