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 new 509 JTTC Ultra still yields a 45-55% reduction in muzzle rise with 115gr ammo

All PMM JTTC compensators mount 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.

The PMM JTTC ULTRA for the FN 509 Tactical and Compact Tactical utilizes a dual 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.

The PMM ULTRA JTTC was designed to work with most factory loaded ammunition and yields and average 45-55% reduction in muzzle climb with 115gr UMC!(please refer to testing charts at the bottom of the product page)

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.

This compensator is SLIGHTLY LARGER physical size in comparison to our single port so if you have a holster, you may need to modify it to accept this compensator.

9mm Ammo known to work well with our dual port comps:

115gr:
-Federal American Eagle
-Speer Lawman
-Wolf
-Remington UMC
-Sig Sauer
-Fiocchi

124gr:
-Blazer
-Speer Lawman
-Federal American Eagle
-Sig Sauer
-Winchester
-PMC
-Remington UMC

Most 147gr ammo will run but you will see less performance due to a lack of velocity
