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


Faxon Firearms compensators are designed for Glock® Gen 4 9mm pistols.  Fitment with other pistols or generations cannot be guaranteed.  Testing for fit and function was performed on these models specifically:  

Glock 19 Gen 4 

Glock 17 Gen 4 

Glock 34 Gen 4 


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: 1.27in

Weight: .06lbs

Thread: 1/2x28


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

    I have this on a GST9 build, with a Trybe barrel, and a GST9 “WREATH” slide. Not only does it look wicked…. The functionality is second to none. Compared to the Strikeforce compensator…. Well it doesn’t even compare.

    Installed on a Shadow Systems MR920 War Poet and it looks outstanding!! I have only been able to put about 30 rounds through it so far, but it seems to really help mitigate the felt recoil! I love it! It's amazing, especially at this price point! I was hoping to be able to upload a couple of pictures here but I don't see that option.
