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.
In order to achieve a flush fit you will need a grip with an extended dustcover. A p365 slide on a p365XL frame will not be flush. A p365 slide on the Sig P365-XMacro Grip module will be flush. For flush fits utilizing after-market grip modules, please refer to the manufacturers fitment guide.
Q: Can I buy just the micro comp?
A: Short answer, no. The barrel and comp are proprietary to one another. Due to the thread depth in the comp and the length of thread on the barrel, our barrel and comp can only be used together.
The PMM p365 micro comp and barrel was designed to work with most factory loaded ammunition and yield a 30-40% reduction in muzzle climb with 115gr ammo

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.
Active Retention (Level 2 & 3) Duty Holsters (Namely Safariland):
PMM Recommendation- RDR Gear
Micro comps and ultra comps cannot be purchased for use with other threaded barrels. The comp and barrel are proprietary to one another. Likewise, PMM proprietary barrels are only for use with the proprietary comp, and cannot be used with suppressors or other muzzle devices.

This is my forth PMM Comp, I started with tje Duty size comp for my P320 full size grip and compact slide for a flush fit build
Then I did a P320 Micro comp on a Compact grip and Sub compact slide for G19 sized comp build
It’s not flush but it’s very close, then I did a G43X micro comp on a CR920 and finally the P365icro comp on a Xmacro grip for a flush build
Very happy with all foir. Could not recommend them enough, you will not go wrong with PMM Comps
