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


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.  


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: 1.4in

Width: 1.1in

Height: 1.4in

Weight: .08lbs

Thread: 1/2x28


*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.

    Excellent quality

    Posted by Brandon H on Mar 4th 2024

    I’m not sure what exactly I was expecting but this comp is such an amazing piece. I haven’t had the opportunity to fire my P320 with the comp yet but it’s such a solid, quality addition to the gun. The fit and finish are impeccable. For reference, I have a P320 XCarry, NSF edition, and there’s virtually no gap between it and the slide.

    Everything Faxon makes is quality and this compensator is one. The machine work, the finish and the function all exceptionally done. I put this on my Sig Legion.

    Haven’t installed it yet on my pistol but the quality and what the functionality of the compensator, I have no doubt it’ll work perfectly.

    Does the job

    Posted by John on May 7th 2022

    This is a well built and effective comp that also looks good on a P320. Actual install is easy if you understand the concept of righty-tighty, but I highly recommend you test fire (then clean the comp and barrel threads again) before you use the red Loctite to make the installation semi-permanent. Breaking the comp lose after the Loctite sets is not going to be fun, so that's why it's a good idea to make sure you have full function and no cycling issues first. Only (minor) downside with this, if you run a Safariland 7x holster, you'll need to remove the barrel plug in the bottom of the holster for clearance, but that's an easy modification.

    Noticeable reduction in muzzle flip

    Posted by Chris Richard on Dec 31st 2021

    Well engineered and quick and easy install. The finish and fit was great installed on my SIG P320. The contours of the compensator also aligned well with the SIG factory slide causing no drag on my holster when drawing my gun.

    Faxon Barrel and Compensator

    Posted by Tom O';Neill on Nov 15th 2021

    I purchased this barrel and the Faxon Sig Compensator for a P320 Full-size build using a Wilson Combat full size grip module, Sig Custom Works FCU and a Full Size P320 slide. I added a Springer Precision Tungsten guide rod and a 14LB spring. The barrel drops in perfectly and with the 14LB spring the pistol runs flawlessly. The pistol is loud but shoots so softly its like shooting a .22 This combo is absolutely the fastest flat shootingest gun in my safe. I consistently shoot better with this than my Legion X Five. I give the barrel compensator combination my highest recommendation. If you're looking for drop in convenience, fantastic finish and precious accuracy order one of the these compensators. You will not be disappointed!
