I was also going to suggest you look at the 38 special group of revolvers. A lot were made and still are being made. Fairly cheap and give you a huge range of various options in different barrel lengthes. Take her to the lgs and let her pick through some of the 2 to 3 inch barrel length models. I'm sure she will see one she falls in love with. Good thing is she can practice with semi wadcutter shaped bullets which have very mild recoil so she will be confident and become a good shot. Then buy some +p ammo just to carry and she won't be afraid to use it if she needs. Most all new S&W revolvers are rated for +p and I wouldn't hesitate to shoot +p out of 90% of the older ones made.
