Sounds like a defective gun....you should just bring it to me.
Ya know I was this <> close to being a shooting instructor many years ago. Would have been a great job but I didn't like the guy who owned the company so I passed.
You did say that gun had long trigger pulls right? Lord knows I hate that and that could be part of the problem. Maybe you should let her find one that shes comfortable with. That is the most important thing anyway. What feels right for you isn't always whats gonna feel right for her. I'm sure she will learn to shoot it but you want her to be very confident with it and right now it doesn't sound like she is.
