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 Recoil Spring Recommendation:

Our ultra comp for the PDP was designed around the factory spring, but you may want to change it out. We recommend not going any lighter than 15 lbs.

We personally like and recommend the ZR Tactical Solutions PDP Captured Guide Rod.


Ammo Recommendations:


Federal American Eagle

Speer Lawman


Remington UMC

Sig Sauer





Speer Lawman

Federal American Eagle

Sig Sauer



Remington UMC


Most ammo will run, but you will see less performance due to a lack of velocity


Ammo to stay away from:

Blazer 115

Winchester White Box 115

Armscor 115

PMC 115

All reloads or reman ammo



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.
