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.

Whoa mama!!! This is the nicest comp. It totally blew my expectations away. Very rarely have I had a comp make a significant noticeable difference. You think the comp and barrel are amazing? Try adding the Icaurus Grip Module that PMM has them make. It is ri-donkulous. I so wish I could post a picture of it here

Finish on the barrel and comp wasn’t uniform, disappointed in the finish for the money it cost. Barrel had a bur/ nick near the bottom where the recoil assembly sits. Went ahead and installed it. Took it to the range to try it out and was disappointed again. Suddenly my p365 xl that had never jammed or malfunction since I had it, started to stove pipe the spent cases. And yes it’s installed and timed correctly. BIG waste of money to me, the comp didn’t make any noticeable difference..

I can not say enough about this comp. I had a stock P365 and comp P365 side by side to shoot and YES, You can tell the difference. Best purchase ever.

P365XL. Awesome. Decreased recoil and increased accuracy. Flawless function. Flatter and faster.
