Faxon Duty Bbl G17 Threaded Black
The Faxon Duty threaded barrel for Glock 17 is a precision-machined upgrade built for shooters who want tighter lockup and enhanced accuracy potential out of the box. Made from triple stress-relieved GBQ 4150 carbon steel and finished with a hard black Nitride coating, this barrel delivers the controlled fit and corrosion resistance you need whether you're running suppressed, adding a muzzle device, or building a custom carry gun. Compatible with Glock 17 Gen1–Gen4 platforms, it threads at 1/2"-28 — the standard for modern tactical accessories.
What sets the Faxon apart is its conventional 1-in-10 inch rifling twist. Unlike factory polygonal rifling, this design handles everything: jacketed target ammo, economical cast lead practice rounds, and heavy subsonic loads without hesitation. That versatility matters if you shoot a mix of ammunition or run a suppressor. The 11° target crown is cut to help keep bullets flying true downrange, and the tighter barrel fit than OEM specs means more consistent lockup shot-to-shot — a real advantage if you care about precision.
Whether you're swapping out a worn barrel, adding a suppressor to an existing G17, or starting a custom build from the frame up, this Faxon barrel is a straightforward, quality upgrade that works. The black Nitride finish handles daily carry and training use without flinching.
