I'm still fussing with my M&P Pro, but I think I'm getting closer. It has an Apex trigger kit and Apex grade barrel, Dawson fiber optic front sight with adjustable rear. My first outing with the Apex barrel wasn't as good as I hoped, but I think I have that problem figured out thanks to TacticalReload (spring in the barrel). Went out today and the vertical spread was better, but I had to move the rear sight so far to side to get where I wanted that I was no longer inline with the bore axis. I didn't have the tools with me, so I called it a day. I did shoot my factory barrel and Apex barrel back to back though. My Apex barrel was about 4" for 5 shot groups at 25 yards and my factory barrel was about 6"-7".
Yesterday, just after installing the Apex barrel I took it out to compare it to my CZ SP01 Shadow with a variety of drills. For accuracy at 25 yards, my CZ shot a 2" group of 5 shots, my M&P was 5". I then did a 5 yard 50 shot dot torture drill, 2" dots. CZ was 45 and the M&P was a 44. Next I did 4 strings of timed plate rack at 15 yards (6 plates) from surrender with a draw and threw out the worst time. CZ was 6.93 seconds average, M&P was 6.31 seconds average.
I want to use my M&P as my IDPA SSP gun. I don't like to de-cock my CZ or have to deal with both DA and SA trigger pulls. I want to just use my CZ for ESP and other games. So for skills that matter for practical pistol games, The M&P is still performing just fine. I'm still trying to get it to shoot 3" groups at 25 yards, I think I would be perfectly satisfied with it if I can. 4" groups consistently would be good enough.
I moved my front sight tonight, then my rear with the laser. I need to go adjust it for real and then repeat the 25 yd accuracy test against the CZ. If the groups are not more than twice the size of the CZ, I guess I'll be ok.
