Glock 43/43X – Faxon Match Series Threaded Barrel – Straight Fluted 9mm – Black Nitride
PLEASE DOUBLE CHECK DETAILS, MODEL FITMENT, THREAD PITCH, SLIDE COMPATIBILITY, MUZZLE DEVICE ALIGNMENT, AND INSTALLATION REQUIREMENTS BEFORE PURCHASE.
Faxon Firearms built this Match Series threaded barrel for Glock 43 and Glock 43X pistols that need a slimline threaded upgrade without cheaping out on the barrel itself. It uses stress-relieved 416-R stainless steel, black nitride finish, straight fluting, conventional button rifling, and 1/2x28 threads in a drop-in package built for factory-spec Glock 43/43X slides.
This one is for slimline Glock owners who want suppressor or compensator compatibility while keeping the pistol in the 43/43X lane. It is not a catch-all Glock barrel, and pretending otherwise is how people buy the wrong part and then get mad at the mailbox.
Fitment
- Fits Glock 43 factory-spec slides.
- Fits Glock 43X factory-spec slides.
- Caliber: 9mm.
- Drop-in threaded barrel for compatible factory-spec slides.
- Thread pitch: 1/2x28.
Does NOT Fit / Verify First
- Does not fit Glock 48 unless your exact SKU specifically confirms Glock 48 fitment.
- Does not fit Glock 42.
- Does not fit double-stack Glock models such as G17, G19, G19X, G26, G34, G45, or G47.
- Does not fit large-frame Glock models such as G20, G21, G29, G30, G40, or G41.
- Do not assume compatibility with aftermarket slides, altered lockup geometry, compensator setups, suppressor setups, or non-standard recoil systems without verifying first.
- Not a non-threaded barrel. If the buyer wants a flush carry barrel, this is the wrong lane.
What It Does
This barrel adds a threaded muzzle to the slimline Glock 43/43X platform while upgrading the barrel itself to a match-style unit with tighter-than-factory tolerance goals. It gives the user room for compatible compensator or suppressor-ready setups without leaving the 43/43X fitment family.
Why It’s Worth It
Plenty of people want to dress up a 43X and call it a day. This actually does more than that. You get threaded capability, a hard-use nitride finish, straight fluting, conventional rifling, and a barrel designed for real work instead of just taking pretty photos.

Tools Needed
No fitting tools should normally be needed for a standard barrel swap in a compatible factory-spec slide, but basic Glock slide disassembly knowledge is required. Threaded muzzle devices may require their own proper tools, shims, pistons, or alignment checks depending on the setup.
Install Notes
After installation, verify barrel lockup, slide cycling, feeding, extraction, ejection, and safe function before live use. If adding a compensator or suppressor setup, verify thread engagement, muzzle-device alignment, recoil-system behavior, and ammunition reliability. Slimline pistols can get picky fast when you start hanging hardware off the muzzle.
Verify Before You Buy
Verify you have a Glock 43 or Glock 43X with a compatible factory-spec slide. Verify to prevent returns: this is not for Glock 48 unless your exact SKU confirms that fitment, and it is not for double-stack Glock slide families. Also verify 1/2x28 is the thread pitch needed for your intended muzzle device or suppressor setup.
