Looks great, performed flawlessly. Yellow spring from the FN factory installed had no cycling issues with 100 rounds of range ammo and a magazine of hollow points. Really takes down the flip of the compact, it almost felt like a 22LR staying on target

Definitely worth the purchase I felt absolutely no recoil, the only issue was getting the correct amount of shims for my FN 509 but once I got the correct amount shims and used the muschi mounting block everything was a breeze after that.

110% would recommend. At first I did not like my FN509, the way it shot and handled I perfered my glock over it. After putting this comp on it felt like a whole new gun. Very fun to shoot. I am now using this firearm as my every day carry just because of how confident I am that I’ll be on target accurately and fast. Easy to install from watching their video. So far I’ve only used Speer lawman 124gr and have had no issues cycling

Product arrived fast. Upon examination the comp was very well machined and finished perfectly. Goes very well with my FN 509c fde. Shim kit and instructions easy to follow. Quality product
