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.

Fit very nicely on my 509 Tactical. A little pricey, but I’m pleased with it overall.

This product is a game changer. Real easy to install with the shim kit. Dry accurate up to 30 yards. Loads of fun.

Have run about 800 rounds through this compensator on a 509T full size. Noticeable decrease in recoil. It’s a joy to shoot. Going to buy another for my 509T compact in the future. Great product PMM. Highly recommend anyone that’s considering it to go for it. You won’t be disappointed.

Awesome! the fit and finish are great. I’ve definitely noticed the difference. It’s not so much that the felt recoil is reduced but the gun returns to so quick and effortlessly! Make sure to use thread locker! My comp has turned slightly without it but the function was not impaired. I will be reinstalling with loctite because this thing is staying on.
