If he can guarantee you will only need it within 7 yards I would be ok. In reality I would want to be efficient to make a longer shot. I shoot my j frames from contact past 25 yards and they are capable given time. I would have someone else shoot it and see if they get the same results. Find someone familiar with j frames or a double action trigger and let them shoot it. Your shooting appears great just off center. I'm not saying it's you but to normally me. I like to rule me out first.
