I would forget about CCW for now. It makes everything too complicated. Just have her focus on finding a gun she likes to shoot. Start with an OWB holster. If she attends any training classes, they'll all start with fullsize or compacts OWB -- no subcompacts or pocket guns, and no IWB. It's easier to teach and to learn the basics of weaponshandling and marksmanship when you control all those other variables like difficult-to-use guns drawn from ankle, pocket, bra or whatever. Keep it simple. Don't add "stopping power" or "concealability" or "comfort of carry" to the equation with the first gun.
