FAXON MATCH SERIES SPIRAL FLUTED THREADED BARREL FOR G43/43X 9MM NICKEL PVD

Pistol Barrels › For Glock® › For G43/43X  |  Works with: EXOS-523 for G43 • EXOS-533 for G43X/48

Fit and Compatibility

This barrel is a direct replacement for the factory barrel in Glock® 43 and 43X slides. It is machined to tight tolerances for consistent lockup, and it drops into factory-spec slides with no gunsmithing. On some aftermarket slides, minor fitting may be needed.

Slim slide: you may need to remove the O-ring from the barrel before seating it in the slide. That is normal for this platform and does not affect function.

Shipping: threaded barrels cannot be shipped to California.

How It’s Made

Every Faxon pistol barrel starts as a long 416-R stainless barrel blank that Faxon rifles in-house before it is ever cut into pistol barrels. That way the whole blank gets the same rifling, inspection, and stress relief, and every barrel cut from it starts from a qualified bore.

1. Drill and ream: 416-R stainless bar gun-drilled and reamed as a long blank
2. Button rifle: Button rifled 1:10, six grooves
3. Air gauge: Bore and rifling air gauged
4. Stress relieve: Stress relieved in-house after rifling, just like Faxon rifle barrels
5. Cut and qualify: Blank cut to length and qualify-turned true to the bore
6. Turn and mill: Hood, lugs, and Spiral Fluted profile turned and milled; 9mm SAAMI chamber and target crown cut; muzzle threaded 1/2x28
7. Heat treat: 416-R heat treated to pistol-barrel hardness; 416-R isn’t hard enough for a pistol barrel as bar stock, while 4150 is
8. Finish: Nickel PVD.
9. Mark and inspect: Laser-marked and final inspected

Six-groove button rifling is land-and-groove rifling, not polygonal, so it runs jacketed and cast lead bullets.

How We Inspect It

Spiral Fluted Profile

Spiral flutes wrap the barrel for weight savings, more surface area for cooling, and a bold look.

Every Faxon Barrel for the G43 / G43X

Add a compensator: Faxon EXOS-523 for G43 • Faxon EXOS-533 for G43X/48. Faxon EXOS® comps thread onto the 1/2x28 muzzle; use the included thread locker on the barrel threads only, not on the set screws.

Match Series G43 / G43X Barrel FAQs

Is this barrel drop-in?

Yes. It is a direct replacement for the factory barrel in Glock® 43 and 43X slides with no gunsmithing on factory-spec slides. Some aftermarket slides may need minor fitting.

How is it rifled?

Button rifled, 1:10 twist, with six grooves. Faxon rifles a long blank in-house, air gauges the bore and rifling, and stress relieves it before cutting it into pistol barrels.

Can I shoot cast lead bullets?

Yes. Six-groove button rifling is land-and-groove rifling, not polygonal, so it runs both jacketed and cast lead bullets.

What is the difference between Duty Series and Match Series pistol barrels?

Duty Series barrels are 4150 CMV in an OEM-style profile with salt-bath nitride inside and out. Match Series barrels are 416-R stainless, heat treated for pistol-barrel hardness, and come in fluted profiles and PVD color options.

What finish is it?

Nickel PVD.

Can I run a suppressor or compensator?

Yes. The muzzle is threaded 1/2x28, the common 9mm thread, and a thread protector is included. You will likely need suppressor-height sights to see over a suppressor.

Can it ship to California?

No. Threaded barrels cannot be shipped to California.

Where is it made?

In Greater Cincinnati, Ohio. Pistol barrels ship without an FFL.
