Faxon Firearms Match Series Barrel for Glock 43/43X - 9mm, 3.9", Nitride Finish

If you're running a Glock 43 or 43X and want tighter lockup, better accuracy, and the durability to handle any 9mm load—including cast lead—a Faxon Firearms Match Series barrel is a straightforward upgrade that requires no gunsmithing. This 3.9" nitride-finished barrel drops into your factory slide with drop-in fit and tighter-than-OEM tolerances that deliver the kind of round-to-round consistency that matters on the range or in a carry gun you trust.

Faxon machines these barrels 100% in-house from stress-relieved 416-R stainless steel, then applies a black nitride coating that boosts lubricity and surface durability while keeping maintenance simple. The straight-fluted design and conventional rifling mean you're not locked into fancy ammunition—run budget plinking rounds, defensive loads, or premium match ammo without worry. The 1/10 twist rate is proven for 9mm, and the target crown ensures consistent bullet departure. For shooters who want their carry or range Glock to shoot like it was born in a gunsmith's shop, this is the move.

The 1/2"×28 threaded muzzle end opens the door to suppressors and compensators if you decide to go that route later. Whether you're dialing in a carry gun for confidence, building a match-grade shooter, or just tired of factory tolerances, Faxon's reputation for precision and hands-on manufacturing backs this one.

Frequently Asked Questions

Will this barrel fit my Glock 43X without gunsmithing?

Yes. Faxon Match Series barrels are designed to drop into factory-spec Glock 43 and 43X slides with no modification required. The tight tolerances actually provide better lockup than stock.

Can I shoot lead ammunition through this barrel?

Yes. The conventional rifling design allows you to safely run cast lead rounds, plated bullets, and jacketed ammunition—no restrictions.

Is this barrel threaded for a suppressor?

Yes. The muzzle is threaded 1/2"×28, which accommodates standard 9mm suppressors and muzzle devices with that thread pattern.

What makes the nitride finish better than stock Glock barrels?

The black nitride coating increases surface lubricity (reducing friction), extends barrel life, and resists wear better than standard blued finishes. It's also easier to maintain and won't rust as readily if exposed to moisture.
