I was having issues firing my XDm. I was shooting left and low. Well, it sounds stupid but all I did was change out the grip2 to grip3. I shot 100rounds today and it shot great. I was using a 2 inch target and my groupings were awsome. I know that it sounds like I am bragging but it's just that I am excited about aiming at something and hitting it dead on feels great specially after thinking that my XDm was messed up.
