***Our 509 comp is NOT compatible with the larger barrel diameter of the FN509 Compact Tactical pistol. ***

Threadlocker must be applied to the set screws once the comp is installed.

Designed specifically for the 509 Tactical, this comp is machined out of 7075 aluminum, and hard anodized or cerakoted, with two top ports and two side ports. The comp is secured to the barrel with a pair of set screws from the underside. The set screws are 6-32 x 3/16, and require a 1/16 in hex key which is included with the order

Barrel thread spec is 1/2 x 28.

FN 509 Comp Installation Instructions

  1. Verify that your gun is clear.
  2. Remove the slide from the frame and take out the recoil spring assembly.
  3. Thread the comp onto the barrel.
  4. Align the top face of the comp with the top face of the slide.
  5. Back the set screws out 2-3 turns and apply a small amount of VC-3 threadlocker to each set screw with a toothpick. **Allow the threadlocker to dry for 30-40 minutes before tightening the set screws.**
  6. Reinstall the recoil spring assembly (we recommend using the Yellow spring set that comes with the 509T).
  7. Assemble the slide back on to the frame, and cycle the slide to verify that the comp is still correctly aligned and does not make contact with the front face of the slide.

    Well finally got to the range to try out my fn tactical with the newly installed Henry compensator. Could not be more happy. The recoil is much flatter. Much better than my Glock with a ported barrel. It also looks great and installation was a breeze. They have a video on their website for installation. I highly recommend this product

    Fit great, Looks great! But I haven”™t been to the range yet but if it works halve as good as it looks, I”™ll be a very happy camper!

    The fitment is perfect (follow the simple instructions). I wasn’t worried about the looks, rather the performance of the comp, and my expectations were met right away with the nearly flat recoil. Highly recommend!

    Beautiful piece and functional, actually made my 509 smoother.

    Following my purchase of the FN 509 tactical, I began looking for a compensator to help tame muzzle flip. Came across a YT video about the compensator from Henry Holsters. Very impressed with its manufacture, looks and function. Fits well and it has helped improve my shooting. I added a thin rubber ring washer to assist with fitment and am very satisfied with this accessorie. Would recommend for all levels of shooters.
