The Faxon Firearms Duty Series G19/G25 9mm threaded barrel is a precision upgrade for shooters ready to move beyond the factory Glock setup. Built from triple stress-relieved 4150 carbon steel, this barrel delivers tighter tolerances than OEM Glock barrels, which translates to improved lockup and better accuracy potential—whether you're running drills at the range, training for defense, or building out a custom pistol. The 1-10" twist rifling handles the full spectrum of 9mm ammunition: standard FMJ loads, subsonic rounds, and even cast lead bullets that factory Glock barrels won't accept.
The half-inch-28 threaded muzzle is ready to accept a compensator, muzzle brake, or suppressor, giving you the flexibility to tune the gun to your needs. A hard black Nitride finish stands up to handling and environmental exposure without the fussiness of stainless steel upkeep. The 11-degree target crown is precision-cut to protect the rifling and support consistent performance shot after shot.
Faxon engineered this barrel for universal compatibility with Glock 19 Gen1 through Gen4 pistols in 9mm SAAMI spec, so it'll drop into your existing frame or serve as the foundation for a custom build. Whether you're suppressing, comp-shooting, or just chasing tighter groups, this is a no-compromise barrel that does the work without the marketing noise.

Frequently Asked Questions
Will this barrel fit my Glock 19 or Glock 25?
Yes. The Faxon Duty Series G19/G25 threaded barrel is compatible with Glock 19 and Glock 25 pistols from Generation 1 through Generation 4, provided they're 9mm SAAMI spec. It will not fit Gen5 frames.
Can I use cast lead bullets and subsonic ammunition in this barrel?
Yes to both. The 1-10" twist rifling is engineered to stabilize subsonic loads and accommodate cast lead projectiles—something factory Glock barrels are not rated for.
What muzzle devices can I attach to the threaded muzzle?
The barrel is threaded 1/2"-28, which is the standard spec for 9mm suppressors, compensators, and muzzle brakes. Any device with a matching 1/2"-28 female thread will mount directly.
Is this barrel more accurate than the factory Glock barrel?
The tighter tolerances and superior stress relief of the 4150 carbon steel, combined with the precision target crown, create better lockup potential for improved accuracy compared to factory barrels. Individual results depend on ammunition, optics, and shooter technique.
