Add muzzle threads, cast lead compatibility, better fit, and better lock-up to your G19 in one fell swoop! The Faxon® Duty Series Barrel features conventional land-and-groove rifling, meaning it can handle cast lead projectiles without issue—solving one of the major shortcomings of the Glock Marksman Barrel.
Each Duty Series Barrel is crafted to tighter tolerances than standard Glock® barrels, and despite being a drop-in replacement, actually provides a better fit and better lock-up. Each Faxon Barrel is manufactured 100% in-house from mil-spec 4150 certified gun barrel steel. From there, each Barrel is then fully stress-relieved, air gauge-tested, and 11º target-crowned for superior accuracy. Finally, each one goes through meticulous testing before being finished in nitride.
