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.

It’s not often I feel like I underpaid for something I wanted rather than needed. I saw this comp/barrel and did a lot of research before buying it, I got it, shot it and can say it was worth the price, plus they gave me a much appreciated veteran discount which all together makes me feel like I still owe them. Hahaha it’s a great product.

Awesome comp & barrel for the 365. Mines on a 365X upper, and a macro frame, giving me the best of both worlds. Took it through a 2 day Defoor pistol course lately, and had 0 issues shooting mostly blazer 124. It’s an equalizer for the small and skinny guns to shoot much more aggressively.

A 365 comp that actually works.

The lack of recoil on my 365x because of this comp is very noticeable. You’re back on target significantly faster than when it was stock. I highly recommend it, especially on these smaller guns and the extra length isn’t noticeable when carrying.
