I am an experienced pistol shooter(plinker) who has been away from shooting for a while and recently started shooting again. I shoot a Ruger Single Six .22, right handed. I have sighted the pistol from a rest to be on target center. Shooting one handed my shots tend to group at 9 oclock on the target. I have worked on my trigger control and am getting the proper "surprise" trigger break. I tend to think the problem may be with my grip. Any suggestions would be much appreciatrd.
