Perhaps a CZ in 9mm Luger for a semi auto. I would take her shooting somewhere to rent/borrow some pieces to see how she likes them. Appearance & feel can be a big difference for the ladies. I would have bought Mrs Biscuit anything she wanted, and she handled many different weapons after shooting mine, but she chose a Smith & Wesson hammerless snubby over all. And the 3 little biscuit daughters shoot it, too. Very popular with 'em. My oldest girl's preference was for a Ruger SA in .32 H&R Magnum, which is out of production for now. Glad I helped her get it last year.
