This Faxon Duty Series barrel is one of the easiest ways to breathe new life into a Glock 22. If you already own the .40 S&W full-size frame and want cheaper range time, softer recoil, and the option to run a suppressor or comp, swapping to 9mm is a smart move. The barrel drops right into factory Gen2-4 slides, so you pair it with 9mm magazines and a 9mm recoil spring assembly and you are off to the races.
Faxon machines these 100 percent in-house from stress-relieved 4150 CMV steel, the same mil-spec carbon alloy they use on their duty-grade rifle barrels. It gets a full salt bath nitride treatment inside and out, which bumps up lubricity, wear resistance, and corrosion protection so the barrel holds up to high round counts. The chamber is cut to 9mm SAAMI spec with a 1:10 twist and an 11-degree target crown, and Faxon uses conventional rifling instead of polygonal, which means you can safely run cast lead bullets without worrying about lead buildup.
Moving from .40 to 9mm is the budget-friendly path to more trigger time. Nine millimeter runs cheaper, kicks softer, and the tighter-than-factory tolerances on this barrel give you a more consistent lockup than the OEM tube it replaces. That translates to better accuracy on paper and a gun that feels a little more dialed in.
The 1/2×28 threaded muzzle is the standard 9mm pitch, so it plays nice with the vast majority of suppressors, compensators, and thread adapters on the market. The barrel is a touch longer than stock to accommodate the threads, so expect it to protrude slightly past the slide, which is completely normal for a threaded setup. When you are not running a device, just spin on the included thread protector and go about your business.
Every Faxon pistol barrel is backed by the company's Lifetime Guarantee against defects in materials and workmanship, which tells you they stand behind the machining coming out of their Cincinnati shop.
The barrel itself drops into your factory Gen2-4 slide, but to actually shoot 9mm you will also need 9mm-compatible magazines and a 9mm recoil spring assembly. Neither of those comes with the barrel. Once you have those three pieces together, your .40 frame will run 9mm without any permanent changes.
No, it is a true drop-in part designed for factory-spec Glock 22 Gen 2-4 slides. Faxon holds tighter tolerances than OEM, so you actually get a more consistent lockup than the original barrel. Basic field-strip knowledge is all you need to swap it in.
Yes. The muzzle is cut with the standard 1/2×28 thread pitch, which is compatible with the vast majority of 9mm suppressors, comps, and thread adapters. When you are not running a device, keep the included thread protector on to keep the threads clean.
It is. Faxon uses conventional rifling on the Duty Series rather than polygonal, so you can safely shoot cast lead ammo through it. That opens the door to cheaper reloads and a wider range of range ammo without the lead buildup concerns some polygonal barrels have.
