My M&P45 shoots low and to the left, not much, about 4 inches low and 2 inches left at 10 yards. I does this with bullet weights from 230 to 195. It's primary role is as a combat sidearm, I can drift the sights for windage but elevation is an issue. My question is for those who have put adjustable sights on your M&P which combat models do you prefer and why? Or, I could always put a lower sight up front.
