I own a couple of FS M&Ps, a Pro and FS both in 9mm. My Pro has been my go to pistol for IDPA and steel matches, and have been very pleased with its accuracy and trigger. My FS was fine, and didn't have any issues, but even after a few hundred rounds and polishing the USB, and trigger bar was not as nice as my Pro. So like a kid caving to peer pressure I went ahead and installed an Apex FSS and polymer trigger. It wasn't incredibly difficult with the exception of getting the trigger pin in(took a couple of attempts), and it only took about an hour and a half going relatively slow. I even adjusted the trigger bar loop just like in the Apex video. Now all I need to do is test it at the range.
