My wife was about as hesitant as any new shooter when I was first teaching her how to shoot. Now she shoots a small 9MM better than I can. I still outclass her with a full-sized handgun like a P229 or CZ75 but damn with those small hands she can make an LC9, K9 or Shield do some magical stuff.
I wouldn't want to be the BG breaking into my home expecting my wife to flinch or hesitate. I am by no means a professional but I have instilled in her if you are going to point the gun at someone it should be because you intend to shoot them. None of this try to reason with, talk to, talk down , hold at gunpoint stuff you see in the movies.
