great advice out there.
i started with 22 about 30 years ago, and when i have not been to range for a while, back to a 22 again to practice trigger control, sight picture.
excitement throws every shooter off.
single action always easier than double action, but once you are comfortable with double action revolver, the semi auto feels like a piece of cake, to me anyway.
there is a bit of follow through, that even when gun recoils, to try to maintain the sight picture a milli second longer and keep hand and arm still on course, something like golf, etc.
there is analysis out there, i just can't remember off hand, as to what the shooter is doing wrong, if the shot goes up vs down, or right vs left, and how to correct against pulling the shots
any cgn'ers recall the drill, and can help out?
whatever you do, sometimes bulleyes can wait, so should the higher calibers, she can work up to it and master it, in shooting sports, women are not the "weaker ###", and they certainly can outshoot any of us. remind her of this fact if you haven't already
IMHO, just make sure you keep her encouraged in the sport, and she enjoy it, That, as you already know, is the most important aspect.
Good shooting to you both!!!
