ULTRA & DUTY INTSALL
MICRO INSTALL
Q: Can I buy just the micro or ultra comp?
A: Short answer, 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 barrel and comp can only be used together.

All of our compensators are tested in a ransom rest and measured with a digital inclinometer.
The PMM MICRO for the Glock 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 Glock 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 Glock was designed to work with most factory loaded ammunition and yields and average 40-45% reduction in muzzle climb (with 115gr UMC)

Douglas Walker –
I have a micro comp on my 43x, 19 gen 4, and my 19x. I did have to use a radian spring and guide rod on the 19x to get it to cycle 115s reliably. 124s and 147s are more reliable. So far the 15lb radian spring seems to be working in the 19x. The micro comp is amazing for the size. It’s a nice add on for the 19x, but where it where it really shines is on the 43x. Completely tames that platform and makes me much more proficient in managing the recoil and more accurate and quick on splits between shots. I would probably not buy again for the 19x bc I was shooting very well with that before the comp with 100% reliability. But for the 43x, I think it’s the best upgrade you can get for that weapon. The 19 gen 4 and the 43x have been 100% reliable without any other changes or mods to the weapon. I’d you have never done an install with one of these before I would recommend you pay extra to get the installation block. I will be a helpful guide to get a great outcome.
