I learned how to shoot with a .22. But when I got my CPL, my husband bought me a Ladysmith, .357 mag. (Of course it will also shoot .38s.) I'm very small, four foot seven and 73 pounds, but it fits me okay.
Revolvers don't jam and if you get a dud, you just squeeze the trigger again. I'm not going into combat. If I'm attacked, I'm sure the five rounds it carries will be enough. (The key, as I've been taught, is shot placement.)
Concealed carry is not a problem. You just get a purse designed for carry. I can access it just as quickly as any guy could get to his. A girl can carry a purse while wearing a mini-skirt and a tank top.
