FN 509 loves it!
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+.

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

Neilson Piston
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.
