Was back at the range again last night and went through another 200 rounds (500 total) on my MP9. Even though I'm off target a little I love this gun. I kept going a little low and left. According to the shooters wheel thing, My finger is not on the trigger correctly, I'm tightening fingers, and jerking. I probably do have my finger position on the trigger off, but I cant tell if I'm doing the others or not. Any of you know of any drywall tricks to help remedy this?
