I was at CC range today also, practicing one of the things that might help you. To shoot a pistol accurately you should:
1. maintain a consistent grip
2. align the sights on the target
3. fire the gun without disturbing the sights.
After shooting pistols for over 40 years, including several years of NRA Bullseye competition, I still have trouble with item three. Suspect that many other people do also. Thus my range time today was devoted to intense concentration on trigger control using a scope sighted S&W M41 in .22 LR. Dry fire practice (WITH EMPTY GUN) helps trigger control too. Remember that practice reinforces whatever techniques you are using in that practice. Unless you use correct techniques during practice you are only reinforcing bad habits. IMO QUALITY beats QUANTITY in practicing. Just my .02.
Good shooting and be safe.
