Faxon Duty Series 9mm Threaded Glock 17 Barrel

The Faxon Duty Series 9mm threaded barrel (brand part no. GA910N17NGQ-T) is a drop-in replacement barrel built for the Glock 17. Faxon machines every Duty Series barrel entirely in-house from stress-relieved 4150 CMV steel, then applies a black Nitride finish that adds lubricity and wear resistance on top of the base material’s strength. Conventional rifling means shooters are not locked into jacketed ammunition the way a polygonal factory barrel is, and better-than-factory tolerances give the slide a tighter, more consistent lockup than the original equipment barrel. With a threaded muzzle, it is built for shooters who want to add a compensator or suppressor to their duty or range gun.
