Questions & Answers
What kind of recoil spring should I get to make this work in my Glock 19 gen 4 Manufacturer Answer

The compensator is designed to work with the factory recoil spring and standard pressure new manufactured ammunition. For lighter loaded ammunition, you may need a lighter recoil spring. We would recommend a 13-15 pound spring if using lighter ammunition.

by Faxon Firearms, Manufacturer, August 28, 2025
does the require a different recoil spring? Manufacturer Answer

The EXOS compensators are designed to work with most commercially available ammunition and the factory recoil spring, however, some tuning may be needed to get fully reliable function on your particular pistol. We recommend starting with the factory recoil spring and then tuning down only if needed with your chosen ammunition.

Product Info for Faxon Firearms EXOS-543 Pistol Compensator for Glock Gen 4 19/17/34

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

Constructed of black anodized 6061 Aluminum, 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.

Faxon Firearms Pistol Compensators have been tested and confirmed compatible with SIG P320 Full-Size pistols. Compensators were not tested on, but reasonably could be compatible with the SIG P320 Compact/Carry pistol, though testing was not done on this model specifically.

Compensators can affect the timing of your pistol and may require adjustments in lubrication, ammunition, and other areas. Fitment with pistols or generations other than the SIG P320 Full-Size pistol cannot be guaranteed.
