Consistency is key. Improve your shot with Faxon Firearms' EXOS Pistol Compensators.  


Faxon Firearms compensators are designed for Glock Gen 3 and Faxon Firearms FX-19 pistols.  Fitment with other pistols or generations cannot be guaranteed.  Testing for fit and function was performed on these models specifically:  

Glock 19 Gen 3 

Glock 17 Gen 3 

Glock 34 Gen 4 

Faxon Firearms FX-19 Hellfire 


Constructed of 6061 Aluminum with a black anodized finish, Faxon Pistol Compensators feature a uniquely angled front port single chamber design, enabling the compensator to improve consistency while reducing muzzle climb and recoil. The angled ports allow gas to deflect upwards as opposed to only deflecting sideways, reducing up and down muzzle movement and improving reliability. Barrel protrusion is designed to fit flush with the slide and has been optimized for Faxon branded barrels. For all other barrels, the barrel should protrude .600” or less for a flush fit. Each compensator comes complete with thread locker, two 6-32 set screws, and a 1/16 Allen wrench. 


Length: 1.1in

Width: 1in

Height: 1.2in

Weight: .06lbs

Thread: 1/2x28


*Compensators can affect the timing of your pistol and may require adjustments in lubrication, ammunition, and other areas.

    This thing is beautiful and an absolute breeze to install. 5 star rating based on that, haven’t tried her out yet. Looks great with my slide from US Patriot Armory. Went cheap with shipping and still arrived in a week. Will update review after 9mm range day!
