Best thing to do, as long as she knows more or less what she doesn't like (your Glock), is to let her handle and/or shoot a variety of revolvers until she finds one whose balance, appearance, trigger, and so forth appeal to her. Bottom line, if you want her to trust the gun and practice with it, let her choose it.
You don't want to spend a lot, I understand, but if you can find a Smith & Wesson 617 that you can afford, you won't regret the purchase. Rugged, reliable, super-accurate, great trigger right out of the box.
