Hi, I had a question that I thought I would ask you guys. I have a target out behind my house. The target is a little up hill from when I stand. I notice that when I shoot here I am a little low and to the left with my M&P .40, but when I go to the target range I am closer to center. I thought at first that it was off mostly because of being up a little higher than where I was standing, but I have never noticed this with any rife or shotgun that I fired at this target. Also my dad has a Ruger GP100 and when we shoot at the same target it is close to center as well. So here is my question. Is there a reason that I am shooting low and left here?
