Don't "get" her anything. Let her shoot everything that fits her hand well at a gun store that rents handguns and go from there.
I got a RIA 1911 .22 and went target shooting yesterday with my wife. We also rented a beretta 92 9mm. She could barely hit inside the bullseye circles on a 5-target sheet and even missed the sheet some of the times. She has very large hands and had great difficulty holding the gun. Once she picked up the Beretta 92, she was hitting excellent groups and had almost all of her shots inside the target near the bullseye.
If I was shopping for her, a 1911 for self defense would have done her more harm than good.
