FOR DUTY & ULTRA INSTALL

 

FOR MICRO INSTALL

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
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 subcompact with Ultra= 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.

PSA:

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.
