If you are looking at concealed carry, the Glock 26 is a 9mm compact. Also fits well in a woman's hand. You would have to deal with the issues of a semi-auto malfunctioning. If you want to do away with that, a small 38 like a S&W Airweight works well. 5 shots and will go bang with each pull of trigger. It is really a matter of personal preference though. Go to a store and handle each and see what you and she likes.
