SIG P320 Full Size – Compensator – EXOS-515 – 9mm 1/2x28
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
The Faxon EXOS-515 is a black anodized 9mm pistol compensator built for SIG P320 Full Size pistols with a 1/2x28 threaded barrel. It is a dedicated fitment part, not a universal “close enough” piece for every P320 flavor under the sun.
This compensator is meant to help reduce muzzle rise and keep the gun tracking flatter, but like most pistol comps, it can change timing and reliability depending on ammo and spring setup. Useful when the gun is built right. Annoying when the setup is guesswork.
Fitment
- Fits SIG P320 Full Size pistols
- 9mm
- Requires 1/2x28 threaded barrel
- Black anodized finish
Does NOT fit
- Do not treat Compact or Carry fitment as confirmed
- Not for non-threaded barrels
What it does
It redirects gas upward to help tame muzzle climb so the pistol tracks flatter in recoil. That matters most on faster strings and when you’re trying to keep the dot or irons from wandering all over creation.
Why it’s worth it
This makes sense for a properly built P320 Full Size setup where the owner actually plans to tune and test the gun. It is not a sloppy universal answer, and that’s a good thing for return prevention.

Install notes
Compensators can affect pistol timing. Expect to test with your actual ammo and confirm reliable cycling before calling the build done.
Verify before you buy
Verify you are running a SIG P320 Full Size 9mm setup with the correct 1/2x28 threaded barrel. Do not assume other P320 variants are confirmed just because they look close.
