Picked up a new M&P 40 over the weekend and took it out today and WOW!!! Put 130 rounds of WWB through it with no problems. I have just in the last couple months stared shooting handguns and with my glock 22 standing freehand at 15 yds. I will get groups of 6-8" and with the M&P I was getting groups of 2-3". I shot one group of 15 in 15 seconds or less and got a group of 4" with one bad shot.
