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.

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.

I loved how great my Sig P365XL could shoot, never would have thought it could get better until I added my comp. I now have PMM comps on three pistols.

The comp/barrel combo is great and does a great job…almost too great. My P365 factory slide, recoil spring assembly, and PMM JTTC 3.1” barrel comp combo did not run well with lighter target loads. It ran P9HST1, P9HST4, and Winchester 124 grain NATO spec ammunition without any stoppages. It makes a very noticeable difference in keeping the gun flatter during recoil and reducing my perception of recoil.
I recommend it if you are looking to make a snappy platform a lot more pleasant. I do not recommend it if a stoppage with lower powered ammunition on the range is going to ruin your day.
I think the performance is worth buying a little hotter range ammo.
Customer service with PMM is great!

This thing is amazing, totally worth it. With this on my P365X, I can do the Dicken Drill in 5 seconds (10 shots, C zone steel, 40 yards, from concealment). I can’t do that with any other handgun. It took a minute and some tuning to get running 100%, but now runs Tula 115 grain with a shitty one handed grip.

I used my PMM JTTC COMP on my Icarus precision 365. It turned an already flat shooting pistol into a freaking race gun. At the local range I have people coming up to me asking what my build is and when they shoot it. They tell me “ I have to build one of those” i can’t recommend it highest enough

Fit and finish is awesome, and it shoots as good as it looks! Definitely recommend picking one up! You’ll thank me later.
