Take her to a range, where they rent guns and let her shoot some different ones to find what she is comfortable with. I teach CCHP and so many times the husband buys the wife a gun that she is not comfortable with, and she will never like it. I had rather my wife have a 22 and be able to shoot it accurate, than to have a 44 Mag, and not be able to shoot it or when she does, not be able to hit her intended target.
