On the G19, the Micro JTTC will take the slide length to the exact same size as a Glock 17!

On the G26, the Micro JTTC will take the slide length to the exact same size as a Glock 19!

On the G17 you will not achieve a G34 length.  It will create a length in between G17 and G34.


G19 and G17 combos will now ship with “blackout” style barrels!


The PMM Compensator uses a proprietary mounting system much like what is found on all modern rifles utilizing a combination of shims and proper timing of the compensator in relation to the Pistol slide.

Additionally, the PMM compensators utilize a single port design at the 12 O’clock position which maximizes the effectiveness of the compensator in keeping the muzzle of the pistol down and allows the slide to “track” faster and more accurately for follow up shots.

We have adapted our designs to integrate with and complement the design of your pistol so no longer does a compensator have to look like an afterthought slapped on the end of your pistol, Rather it Delivers unmatched performance and looks.

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 Recommendation-

Cascadia Concealment 


Tier 1

You will need a G34 length or open ended holster for both options.

Active Retention (Level 2 & 3) Duty Holsters (Namely Safariland):

PMM Recommendation- RDR Gear

You will need a G34 length holster. Additional, the holster plug will likely require modification/removal for proper lockup and function.


G19 w/Single port JTTC or Dual Port JTTC = In between length and a G34 holster is required.
G19 w/Micro comp combo is the exact lengh of a G17 so a G17 holster is required.
G17 w/Single port or Dual Port JTTC = G34 length and a G34 holster is required.
G43/G43x with micro comp is a the length of a G48 so a G48 holster is required.
G48 with micro comp is G17 length.

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.
P320 compact with GEN 2 = Lenght of full size P320 so F/S P320 holster required.
P320 subcompact with MICRO= about 1/4″ longer than a compact P320
P320 compact with Micro you will need a Full Size P320 holster
P365 with Micro comp= P365XL length and a P365XL holster is required.
P365XL with Micro- Comp adds 1/2″ in length.

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.
