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.

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.

Note: Threaded pistol barrels are not legal in all areas. It is your responsibility to check your local laws before ordering a threaded barrel.  You also understand and agree that all firearms and firearms related activities are potentially dangerous if handled/conducted improperly and can pose risks and hazards to yourself and others, which may result in property damage, serious injury or death.


PMM suggests using high quality holster manufacturers and not ones who skimp on material and care more about marketing.. We have great success with T-Rex Arms and Tier 1 Concealment.
T-Rex Arms also has a “threaded barrel” option on its holster builders and this option will cover our Micro comps perfectly.
