Seriously, welcome aboard! Take her to a range that rents guns and let her shoot them. They may be having some ladies events at PSC or Thunder. Other people would let her try out their guns. Shooting a gun is the best way to tell if you like it.
I took my wife all the way to Austin, because Red's was the only place I could find that had a Kahr for rent. She shot it, she didn't like it, I saved $500!
My wife didn't like A LOT of guns. I thought a SIG P239 was too heavy to carry. That's the one SHE loves(P239/40s&w). She carries it.
Good Luck, Have Fun, OE
