Want to run a can or a compensator on your Glock 17 without sending anything off to a smith? This is the barrel that gets you there. The Faxon Duty Series threaded barrel drops straight into a factory-spec G17 slide (Gen 2-4), swaps in during a normal field strip, and threads at the standard 1/2×28 pitch so it plays nice with most 9mm suppressors, comps, and the Faxon EXOS line. It's chambered in 9mm with a SAAMI-spec chamber and spins a 1:10 twist that stabilizes everything from light range ammo to heavy subsonic loads for suppressed shooting.
Faxon machines these 100% in-house from stress-relieved 4150 CMV steel, the same mil-spec carbon alloy used in duty-grade rifle barrels. That means it's built for high round counts and hard use rather than looking pretty on a shelf. The whole barrel gets a full salt bath nitride treatment inside and out, which bumps up lubricity, wear resistance, and corrosion protection. Tolerances run tighter than OEM, so you get a more consistent lockup than the factory barrel it replaces, and that pays off in repeatable accuracy over time.
Here's a detail that matters if you shoot a lot or roll your own: unlike Glock's polygonal factory rifling, the Faxon barrel uses conventional button rifling. That opens the door to cast lead bullets, which is a big deal for anyone buying in bulk or reloading on a budget. Pair that with an 11-degree target crown for clean, consistent bullet release and you've got a barrel that earns its keep on the range.
The threaded muzzle protrudes past the slide, which is normal for this style, and it ships capped with a knurled thread protector so the threads stay clean until you're ready to mount something. Whether this is a straightforward upgrade to your carry or home-defense G17 or the foundation for a full custom build, it's a rugged, no-drama place to start. Every Faxon Glock barrel is backed by their Lifetime Guarantee.
Yes. It's a direct replacement for factory-spec Glock 17 Gen 2-4 slides with no fitting or gunsmithing required. Field strip your pistol, pull the factory barrel, drop this one in, reassemble, and run a function check before live fire.
The 1/2×28 thread pitch is the standard for 9mm and is compatible with most suppressors, comps, and muzzle devices, including the Faxon EXOS line. Keep in mind that when you add a can or comp, you may need a lighter recoil spring for reliable cycling. The threaded muzzle also protrudes past the slide, which is completely normal for this style.
Absolutely. Faxon uses conventional button rifling instead of Glock's polygonal factory rifling, so cast lead loads are safe to run. That makes it a great pick for reloaders and anyone buying ammo in bulk.
It's machined from stress-relieved 4150 CMV steel, the same mil-spec carbon alloy found in duty-grade rifle barrels. The barrel then gets a full salt bath nitride treatment inside and out to boost lubricity, wear resistance, and corrosion protection. It's built for high round counts and hard use.
