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 Install Video (Same for G43/G43X/G48 as P365)



We have seen issues with Shield arms mags.  If you are having issues running these mags we have been told leaving the mags loaded for a few weeks and keeping the mag spring under tension helps clear up the issue.


Recoil Reduction:

All of our compensators are tested in a ransom rest and measured with a digital inclinometer.

The PMM MICRO for the Glock slimline was designed to work with most factory loaded ammunition and yield 30-35% reduction in muzzle climb (with 115gr UMC)



PMM Holster Recommendation:

PMM Recommendation-

Cascadia Concealment 


Tier 1

Active Retention (Level 2 & 3) Duty Holsters (Namely Safariland):

PMM Recommendation- RDR Gear


G43/G43x with micro comp is a the length of a G48 so a G48 holster is required.
G48 with micro comp is G17 length.


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.
