I am retired and I am somewhat new to shooting. After trying out a number of pistols for IDPA use, I seem to like the way the M&P pro series 5" feels and fits my hand. When I shoot off of a rest at 15 yds. I can shoot 3 inch groups with several guns, even though they don't feel as good as the S&W. My question: the M&P simply won't shoot that small a group. It shoots larger inconsistent groups.
I have been told my several knowledgeable people, that average accuracy is inherent in this make and model of gun. Please advise!
