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.

Fast shipping. Easy installation. Noticeable difference in recoil reduction. Plus it makes my FN 509 look awesome.

Not PMM’s fault but I’m glad that you guys ship insured. I’m guessing someone’s decided to help themselves to a nice stolen comp through the mail. Well I hope they at least have a 509T lol. Dealing with my slow post office but I see no reason why they should not replace it for me. Also I’ve fired my buddies PMM comp on his and it was a dual port, sadly I didn’t have that option. Hopefully if and when they refund me I will maybe have a 2 port option. Thanks guys keep up the great work.
