Thinking of a new .22 mag pistol for my wife. She is a dead on shot at most and range with her current .38 snub nose on the first shot, but she does not have the hand strenght for follow up shots. She stays dead center but the gun seems to roll in her hand and each follow up shot is just up about 2" higher at 25 feet. And yes we have tried many different grips on the gun. Any thoughts on changing to the 22 mag?
