I bought an M&P9 at a gun show three weeks ago. We started out shooting low-left fairly consistently. I liked the way the pistol handled and shot, but the low-left was a bit disconcerting. The posts on this site pretty much confirmed that the shooter wasn't doing the pistol justice and I started working on shooting mechanics. It looks like I had used the adjustable sights on my .22's to hide some poor trigger techniques. The front sight was a bit off to the right. Yesterday with a slight correction on the rear sight, a slight change in grip and more attention to the trigger, the gun that was shooting 2" left all of a sudden starting centering around the X at 15 yards. In the last two mags 27 rounds were in a 2" group, 3 rounds were outside that and 4 very consistent shots low, 6 o'clock at 4".
As best I can tell the only part of this gun that shoots badly is the part that connects the eye to the trigger. It's fed every round put in the mag (mostly Walmart $12.88/100 Winchester 115 gr FMJ), fired every round. Ergonomics are great. The only problem I see with it is that it actully shoots where I really aim it, not where I thought I was aiming.
