Faxon Duty Series Barrel | G19 9mm 4.5in Threaded

The Faxon Duty Series barrel for Glock 19 is a threaded, drop-in pistol barrel chambered in 9mm Luger. It ships with a black Nitride surface finish and a threaded muzzle compatible with 1/2-28 accessories. The barrel is produced to tighter-than-factory tolerances and uses conventional/button rifling with a 1:10 twist and an 11-degree target crown. It is designed to install into factory-spec slides without gunsmithing.

Typical applications include everyday carry (EDC) and competition or precision practice where a threaded muzzle and improved lockup matter. The barrel is also compatible with a wider range of ammunition, including cast bullets, due to its conventional rifling.
