    FN 509 loves it!

    Posted by Lee on Mar 20th 2024

    This was a great upgrade to my FN 509, with the R9 suppressor its awesome. It never jammed, didn't get gassed out, had loads a fun, got used to the slight recoil feel on the wrist, but I'm girl with skinny wrists. I ran many top brands and grains and shot flawlessly, accurate at pistol range 10 yards+.

    Very satisfied! Used with an YHM R9. Didn’t notice the extra 10oz hanging on tightly. Improved pattern at 15 yards.

    Gotta have this with the Nielsen Booster to run a suppressed handgun. Now my R9 works like it is supposed to. It’s a must have and it works.
