43X threaded barrel in 9mm — a direct drop-in replacement for the factory Glock 43 or Glock 43X barrel with no fitting, no gunsmith work, and no frame modification. The 1/2x28 muzzle threading opens the platform up to a subcompact-width compensator, thread protector, or a properly-rated 9mm suppressor while the aluminum 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.
Suppressor and recoil-spring notes: The 1/2x28 pitch is compatible with common 9mm cans including SilencerCo Osprey 9, Rugged Obsidian 9, and AAC TiRant 9M when a booster / Nielsen device is fitted. If you run the G43X (13+1) with a suppressor or heavy comp, watch for short-stroking on light 115gr practice ammo — a slightly heavier recoil spring (Wolff 15lb replacement) restores reliability without shifting point of impact. G43 (6+1) tolerates the same barrel without spring changes.
