Went out the other day to shoot my new full size 2.0. At seven yards it was shooting 4 inches low and that was taking a full sight,(i.e. covering the target with the front sight blade). I normally prefer a six o'clock hold at that distance. Now this is my third M&P I have a standard 1.0 and a M&P Pro I shoot those just fine. My buddy also shot low with it.
My question is should I call S&W and see what they say, or just put adjustable sights on it. Has any one else had this problem? Thanks Happy Fathers Day

P.S. I was shooting 124gr. FMJ I also tried 115gr. FMJ with no real shift in impact still low.
