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.

Very easy to install and works a treat. I have seen an immediate improvement with the handling of my FN509.

Nothing less than perfect, shipped and delivered fast. Easy install, and functions great. Ive cycled 300 rounds so far without a hiccup. More than happy with this comp
Rob K. –
Works well. Looks great. Color is slightly different than the fn pistol but the slight shade difference is very complementary to the pistol. Fit is excellent! Had ran over 1000 rounds so far and it is doing very well.

Won’t lie, took me a while to get the set up right, but now that it’s on… AMAZING.. can feel the difference on repeated shots. Looks like it was always on the weapon. Great work! Highly recommend to anyone thinking of fitting a compensator on the FN509
