Questions & Answers
Will this comp fit and XTS gen 3 Glock 19 threaded barrel? Manufacturer Answer

The compensator will fit any barrel with 1/2x28TPI threads and no more than .600" protrusion from the muzzle of the slide. We have not tested with XTS barrels specifically, but so long as they meet the above specifications, it should work.

by Faxon Firearms, Manufacturer, April 2, 2025
What's the thread dimensions? Expert Answer

The Faxon Firearms EXOS-513 Pistol Compensator uses 1/2x28 threads and was specifically tested with Gen 3 models of the Glock 17, 19, and 34. As long as your barrel protrudes 0.600" or less you will have a flush fit. Specific information regarding the threads on the compensator are not provided by the manufacturer.

I installed this on my Ruger RXM and I love it! by Adam, Verified Owner, July 26, 2025
I installed this on a matching Faxon barrel into my Ruger RXM. It shot crazy flat. I did install a lighter recoil spring prior to the Comp/Barrel combo. This caused failures to achieve battery. I reinstalled the factory guide rod and it ran great. Su...

Got one for my sw2 palmetto state dagger slide and one for sw6. Fits great and does not affect my ammo choice. I like that it doesn’t attach to the guide rod, but has tightening set screws. Looks great on my daggers

Product Info for Faxon Firearms EXOS-513 Pistol Compensator for Glock and FX-19

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

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 3.

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. 

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