PMM Compensator for Smith & Wesson M&P 2.0 9mm with Factory Threaded Barrels

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.

PMM compensators utilize a single port design at the 12 O’clock position which maximizes the effectiveness of the comp 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 function of the pistol 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.

Please note, this comp was designed to fit both the 4.6 threaded barrel for the Spec Series M&P 9 2.0 compact & 4.625 threaded barrel for the full size M&P 2.0. The fitment on the 4.625″ length barrel (full size) will be on the tight side. Fitment will vary (depending on start/ stop position of threads on your barrel), but you may need to use only a minimal amount of shims (.002 or .005). The position of the comp pre-install may be pre top dead-center. Please refer to our install video below to make sure you are properly installing your comp.
