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.

Performed flawless. Just put 500 rounds through it with no issues. Felt a noticeable reduction to muzzle flip. Great design and easy install.
William E. –
Comp looks great, very solid construction. Install was tedious trying to get it clocked correctly. Had to watch a video by PMM YouTube to get it right. I wish there was some instructions included in the box, how to install, how much loctite to use. My gun however may need a break in with the comp on or try different ammo. With the normal spring, it will fail to feed about every 3 rounds. With the low recoil spring in it feeds fine but fails to lock open on the last round. Again, gun issue I think. Recoil reduction is noticeable. Only reason not 5 stars is that the comp did not come with instructions in the box.

Followed the how to video and it was a snap to install. Very pleased with the reduction in rise.

First and foremost the compensator overall is 5 stars! Performs well and even though the installation was kind of a pain, it’s by far the most solid mounting so removal is not going to be easy either. The downside is that I wish it was a little easier to remove so I could use my IWB holster still. But I can’t really say anything negative about the compensator! Great product and finish!

After trying different compensator and muzzle breaks none seemed to work well with my FN 509T. It either didn’t look right or the compensator spun around no matter what I did. The Parker Mountain Machine compensator is perfect in appearance and function. Wish I got this earlier, I’ve wouldn’t saved money.
