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.

This thing is amazing!!! Installing did take a little time to get it just right, but definitely worth taking the time and effort. As far as functionality goes, this thing does exactly what it’s meant to. At the range I go to where only 3 rounds at a time can be fired I noticed right away the recoil reduction. HOWEVER, when I went shooting in the woods with no restrictions and ripped through full 24 round mags is when I noticed this things full potential. The return to 0 on this thing when rapid firing is insane…almost as if it never leaves 0!!! Would love to send in pics if that’s something you guys would or could include in the review!?

I love shooting my 509 tactical. I train hard with it and can handle it really well. The comp was kinda a curiosity to me. So for a hundred bucks I figured what the hell. First off the quality and shape of the comp is perfect. All the lines match the gun perfectly. If you didn’t know better it looked like it came out of the factory that way, seamless. Like I said I train very hard ‘ my 509 is a war machine. So I shot it with the comp on. All I can say is WOW’ WTF. The recoil feels like a 22. Almost has no noticeable rise. Back on target almost immediately. I couldn’t believe it. I actually laughed outloud. Shot it all day at the range ‘ didn’t even pull out my sig m18. So hats off to ya parker mountain. You made a amazing comp. Looking forward to seeing what technology you bring to the table next.

I bought a compensator for FN509 and it was super easy to install and i love the way my 509 shoots with it. One of the beat purchases I’ve bought for my gun. Also love the look of the compensator on my fire arm. Im going to suggest this product to everyone looking for compensator
