Drop-in Glock 43X threaded barrel in 9mm — a direct replacement for the factory G43 or G43X barrel with no fitting, no gunsmith work, and no frame modification. The 1/2x28 muzzle threading opens the platform up to a compensator, thread protector, or a properly-rated 9mm suppressor while the exposed thread protector stays flush with the slide when unmounted.
Specs & features:
Compatibility notes: The G43 and G43X share the same slide-and-barrel footprint, so a single threaded barrel covers both frames. Match this barrel to a subcompact-width 9mm compensator — full-size G17 / G19 / G26 compensators are wider than the G43 slide and will not sit flush. The Faxon EXOS-533 is the correct dedicated G43 / G43X / G48 compensator. Verify factory ammunition is 9mm Luger (9x19); the barrel is not chambered for +P+ hot-loaded proof loads. Break-in of ~50 rounds is recommended before mounting a suppressor for the first time so any surface flash from the nitride bath fully burnishes.
