I have owned a M&Pc 9mm for a year now. The gun carries well in my CCC Shaggy, but for me it does not offer any advantages over a Glock 19. With the flat magazine base plate used, the M&Pc truly disappears with the Shaggy. When I use the standard magazine with the finger groove, the M&P is slightly smaller than my G19, therefore not offering any huge advantage.
Two weeks ago, I ran a side by side comparison between my G19 and the M&Pc. I wanted to see how my performance was different between the two.
The G19 won the contest, although I cannot find the actual numbers to share (My notes are scattered from a move). The drills run on that day were 3-2-1, D2, Bill Drill, and the F.A.S.T.
The G19 had a slight edge on the M&P in speed, and I shot with more accuracy with the G19. I had lots of misses with the M&Pc during the 3-2-1 drill. I tried pushing the M&P as fast as I could to keep up with the G19, and that is what lead to the misses during the 3-2-1. My accuracy improved once I slowed down with the M&P.
The factory trigger broke in nicely on the M&Pc. It is a touch heavier than my factory Glocks. If I were to guess the weight, I would say around 6-6.5 LBS. The gun was built in October 2012.
That is my take on my M&Pc. Good luck!
