PMM has adopted the technology from our Ultra Barrel and Comp Combo series and applied it for use on the factory threaded barrel utilized on the 509 Tactical series of pistols. While slightly larger in overall length, our 509 Ultra yields a 45-55% reduction in muzzle rise with 115gr ammo
This compensator is LARGER in size in comparison to our single port so if you may need to modify your holster to accept this compensator.

As always top notch work. I know that there are other companies out there that offer similar services, but IMO PMM offers the best comps and the best slide service around. PM
will always have our business.

I never really gave into the comp hype previously. But this thing works, and it works extremely well. Almost like a cheat code for your FN.
Also, the 2 chamber comp is a bit long for a safariland als. So you’ll need a heat gun and to re drill a new hole for the support screw in order to make it fit. Its a 1 beer job, could be done in two if you like to chug.

Great quality compensator. It fits perfect on my 509C Tactical. The FDE finish is excellent. It came very well packaged as well. However, I had several failure to feed issues with new 124 9mm ammo. I switched to 115 and didn’t have any issues. I emailed PMM to ask if the dual port compensator could only use 115 9mm ammo. They asked if it was remanufactured and what kind of ammo I used. I replied to their questions and never received a response to my question ( reason for the 3 stars). I’m okay if it only works with 115 ammo. I just needed an answer to know to buy 115.

Hi Abraham, please email me directly at justin@parkermountainmachine.com. Your comp should cycle 115 and 124, let’s figure this out!

Had multiple issues with different ammo types. Tried brand new ammo in 124 and 115 with suggested ammo. Sent in videos per requested with the answer of send us your pistol so we can see. Unfortunately not gonna send my pistol in when I showed on video of the issues happening and proof wasnt what they said it could be.

Hi Codey,
We are genuinely sorry to hear your issues with the our comp. Generally rule of thumb with all comps are they are great for 2 things, muzzle reduction with squared away shooters and bringing out poor grip/qualities with not so squared away shooters. You sent in a few videos of you with no eye protection and shooting sideways from the hip. We were trying to be as polite as possible in stating that the malfunctions were 100% shooter induced. We offered you to send in your complete upper so we can test in house while we film and report back our data. We offered to refund/replace the parts if they happened to be the cause of the malfunctions. This is our process, we always test the product in house prior to refund/replacement because 9 out of 10 times it is shooter induced. We get that in this day and age everyone wants the aftermarket parts they see online.. As a very small American manufacturer of these parts we greatly appreciate everyone who supports us. With that being said, please find some reputable training organizations in your area and focus more on training and getting your grip and safety measures squared away. The offer still stands for you to send in your slide and have us test the comp in house. Like previously mentioned in the email chain with you this is a very fast process and you will get your slide back within days.

Threw this bad boy on my brand new, never fired 509c Tac . First 72 rounds, I jammed like 25-30 times. Talked to the range guys got mixed opinions, lubed up my slide, gripped tighter, and threw another 66 rounds through it jammed once.
100% believe my own handling of the weapon was the causation of the jams on top of no lube and she hadn’t been broken in.
100% satisfied
