The Faxon Firearms Exos-523 compensator is a purpose-built muzzle device for Glock 43 pistols designed to tame recoil and muzzle climb on your carry or range gun. Built from 6061 aluminum with a durable black anodized finish, this 9mm compensator uses a uniquely angled single-chamber port design that directs gas upward as well as sideways, reducing both vertical and horizontal muzzle movement for faster follow-up shots and improved shot-to-shot consistency.
The Exos-523 is engineered to mount flush with the Glock 43 slide when paired with Faxon barrels, or with any quality 9mm barrel that protrudes .600" or less. Installation is straightforward: the package includes thread locker, two 6-32 set screws, and a 1/16" Allen wrench to get you up and running. The angled port geometry is the real story here—instead of just pushing gas to the side (which can actually increase some recoil components), Faxon's approach deflects gas upward to counteract muzzle climb, keeping your sights on target between rounds.
Keep in mind that adding a compensator changes how your pistol cycles, so you may need to dial in your ammunition choice, lubrication schedule, or shooting technique. This is normal and expected behavior with muzzle devices. If you're running a Glock 43 and want to reduce felt recoil without changing platforms, the Exos-523 is a solid, no-nonsense option backed by real engineering.

Frequently Asked Questions
Is the Faxon Exos-523 compensator compatible with Glock 43 pistols?
Yes. The Exos-523 has been tested and confirmed compatible with Glock 43 pistols. For a flush fit with the slide, use it with a Faxon barrel or any barrel that protrudes .600" or less from the slide face.
What's included in the package?
Each compensator comes with thread locker, two 6-32 set screws, and a 1/16" Allen wrench for installation.
Will a compensator affect how my Glock 43 cycles?
Yes. Compensators can affect pistol timing and cycling, which may require adjustments to your lubrication, ammunition selection, or shooting technique. This is normal with muzzle devices and is why working through a couple of different load combinations is often necessary to find what runs reliably in your gun.
