There have been countless reports on the M&P Forum saying the same thing. The gun shoots low/left. Most all were corrected by shooting practice and becoming familiar with the new gun. One thing you could check is to make sure your front sight is centered on the slide. Mine was about 1/8th of an inch to the right and it WAS shooting left. The sights will move but the slide needs to be mounted in a solid vise and struck on the base with a brass punch. Caution when removing the rear sight...there is a cap and spring under the rear sight that operates the firing pin safety. Once the sight is loose, put the slide in a plastic sandwich bag to remove it the rest of the way. The sights are removed from left to right and installed in the reverse.
