FOR DUTY & ULTRA INSTALL
FOR MICRO INSTALL
FAQ:
Q: Can I buy just the comp to use with my factory threaded barrel?
A: 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 barrels and comps can only be used together as they are sold.
Q: I have your P320 micro barrel and comp combo. Can I buy just an ultra comp to use with my barrel?
A: No. The duty and the ultra barrels / comps are interchangeable, but the micro threaded barrel is a separate thread pitch so only the micro comps will work with those barrels.
Q: My slide has a loaded chamber indicator. Can I use your barrel and comp?
Yes. But you must first remove the indicator from your slide since our barrels do not have an LCI notch.
Recoil Reduction:
The PMM MICRO for the P320 was designed to work with most factory loaded ammunition and yield 30-35% reduction in muzzle climb (with 115gr UMC)
The PMM DUTY for the P320 was designed to work with most factory loaded ammunition and yield 30-35% reduction in muzzle climb (with 115gr UMC)
The PMM ULTRA for the P320 was designed to work with most factory loaded ammunition and yields and average 50-55% reduction in muzzle climb (with 115gr UMC)
Flush Fit:
There are only two ways to achieve a flush fit using our barrel and comps without modifications:
- Subcompact slide, PMM subcompact ultra comp and barrel, full sized frame
- Compact slide, PMM compact duty comp (previously called the “gen 2 comp”) and barrel, full sized frame
PMM Holster Recommendation:
Cascadia Concealment
T-rex
Tier 1
Active Retention (Level 2 & 3) Duty Holsters (Namely Safariland):
PMM Recommendation- RDR Gear
P320 subcompact with Micro Comp= about 1/4″ longer than a compact P320, so full size holster required.
P320 subcompact with Duty comp= About 1/4″ shorter than a full size, so full size holster required.
P320 subcompact with Ultra= Length of full size P320 so F/S P320 holster required.
P320 compact with Micro Comp you will need a Full Size P320 holster.
P320 compact with Duty Comp= Length of full size P320 so F/S P320 holster required.
P320 compact with Ultra= Right around X5 length so a X5 holster is required.
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.
