1 x FN 509 Compensator
1 x Shim Kit:
Optional “Muschi” Mounting Block
NOT Compatible with:
The PMM Compensator uses a proprietary mounting system much like what is found on all modern rifles utilizing a combination of shims and proper timing of the compensator in relation to the Pistol slide.
Additionally, the PMM compensators utilize a single port design at the 12 O’clock position which maximizes the effectiveness of the compensator in keeping the muzzle of the pistol down and allows the slide to “track” faster and more accurately for follow up shots.
During testing the PMM compensators were designed to work with most factory loaded ammunition but will yield the best results with a +P or Nato spec cartridge. We have adapted our designs to integrate with and complement the design of your pistol so no longer does a compensator have to look like an afterthought slapped on the end of your pistol, Rather it Delivers unmatched performance and looks.

Top quality workmanship on the comp! Recoil is significantly reduced and muzzle rise is all but non existent. Only 4 star rating based on the shims. To install and remove the comp to ensure it was timed correctly before locking it down caused the shims to slip and go out of shape which caused me to add and subtract several times. Other than the shims, it’s a siloed 10 on a scale of 5…. would definitely buy again.
