I have 6 M&P's, 5" pro's in 9 and 40, 5" performance center ported 40, and full size 9 and 40, and my EDC 40 Shield, all have the apex kits in one form or the other and all have benefitted from them. The shield, ported 40 and the 9 pro have the complete kits with triggers the other the competition kits in them. They are all great but different. Keep in mind that if you want to compete with it external mods such as triggers put you into different competing divisions depending on the shooting discipline.
