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.

Most ammo will run, but you will see less performance due to a lack of velocity
I purchased the double port compensator for my FN 509 Tactical. I also purchased the muschi block so I could get it tight without marking up the surface. This compensator not only works well but it looks really nice on the gun. I’m more of a function over form guy. This has both function and form on it’s side.

This compensator delivers on what’s promised! Took it off for a few rounds and the 45-50 vertical recoil reduction is legit! A great gun to begin with but with the compensator it shoots like a dream. Thanks Parker mountain!

Looks great, fits perfect, really helps keep it shooting flat, can tell the difference from single port comp.
