Product Details

Package includes PMM barrel and single port JTTC for either Gen1-3, Gen 4 or Gen 5


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.

During testing the PMM compensators were designed to work with most factory loaded ammunition but will yield the best results with a +P or Nato spec cartridge. 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.



1 x PMM Compensator

  • 7075 Aluminum finished in a type 3 class 2 Black or FDE hardcoat anodize.
  • No set screws, mounts like a muzzle device on a rifle.
  • Captured design ensures that even if your comp comes loose it will not come off or impede function.
  • Technology born and improved upon from our PMM X-Comp pistol.

  • 4 x 0.010″ Shim
  • 2 x 0.005″ Shim

Please note, we are transitionally from a laser engraved logo to a machined (“blackout” style) logo. At this time the g19 barrel is offered in both, the g17 (gen 1-4) is laser engraved only, the g17 (gen 5) is a machined logo only.


Please note, we are currently transitioning the comp style to no side pockets. This is purely an esthetic change. Unfortunately we are not able to offer a style choice, and the new comps will be transitioned in as the pocket-style are sold out. Glock gen 5 in black then FDE, followed by gen 3 and gen 4 comps.


Gen 5 Glock Combos will fit the Gen 5 19, 19X, and 45.
