Faxon Firearms Duty Series 9mm Luger Threaded Barrel for Glock 17 Gen 2-4 - Black Nitride

The Faxon Firearms Duty Series threaded barrel is a drop-in replacement built for the full-size Glock 17 in 9mm Luger. Designed as a direct fit for Gen 2 through Gen 4 pistols, this barrel installs without gunsmithing and maintains the factory slide fit and function.

The barrel is machined from 4150 CMV steel and finished in a black QPQ nitride coating inside and out for enhanced corrosion resistance, lubricity, and long service life under heavy range use. Conventional button rifling with a 1:10 twist stabilizes the full spread of 9mm projectiles, from lightweight target and defensive loads to heavy subsonic bullets.

The muzzle is cut with standard 1/2x28 threads, allowing the shooter to attach a compensator, suppressor adapter, or any other 9mm-compatible muzzle device. With its straight drop-in profile, threaded muzzle, and durable nitride finish, the Faxon Duty Series barrel is a practical upgrade for range, defensive, and duty applications.
