I coach pistol,and have taught quite a few young shooters,if she is not very strong,get her to stand square to the target and grip the pistol 2 handed. I find that kids get discouraged if they can't hit the target,so we sometimes use fun targets rather than scoring ones,there are lots you can download and print on the Internet,if you can make it fun,she will enjoy shooting,and want to continue,don't go spending on a new light pistol until you know she will continue with the sport,kids can be very fickle!
