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.

The fit and finish of the compensator were perfect. The included shims worked great. Took a few test fittings to line mine up correctly. Applied the supplied thread lock and finished the install. 100% happy with the purchase.

Perfect fit and finish. NO locking screws needed. This was a big factor for me.

I noticed a great deal of recoil reduction using this compensator. The machining is well done, however for first time buyers, the coating used is also in the threads, so if you feel resistance while threading it, that’s just the coating, and shouldn’t do any harm to your threads.

This compensator is exactly what I was looking for great color match easy to install put over 500 rounds through it with the compensator staying tight.
Noticable differences in recoil helping to get back on target quicker.
Highly recommended!!!
