I have small hands myself and most .45s feel like boat-anchors to me.
Try these automatics, see what she likes.
VIS-35 RADOM (full-sized gun, 9mm, thin, single-stack, weight absorbs lotsa kick)
Tokarev (problem here is length of the butt. but they are fun to shoot. Also easy to rack if you know how to #### the hammer.)
Luger (just balances so beautifully in the hand, points instinctively and it's pure history)
Helwan Brigadier (Egyptian-built copy of Beretta brigadier, single-stack, steel frame so it's nice and heavy, soaks up the recoil)
When my Mom still was living, often I would have to go away for economics and banking seminars. I have small hands but hers were much smaller than mine, as makes sense. I would leave her my Smith & Wesson Canadian-contract Model 10 in .38-200, loaded with .38S&W rounds with Hornady XTPs. She never had to use it, which was nice, but she liked having one around. Her hands were crippled with arthritis, so she couldn't use her own gun, which was a .455 copy of a top-break S&W.
And then there's the one that most folks forget and it just happens to be brick-reliable, fairly accurate and has very little recoil: Webley Mark IV in .38-200.
You will note that none of what I have suggested are top-dollar pieces and, in fact, you can find most of them fairly reasonably, with the possible exception of the Radom.
Hope you can find something that she likes. The more women we can get into shooting, the better-off we will be. Once enough of them start shooting and discover that it's a lot of fun, I wouldn't want to be the bureaucrat who tries to take away their toys! Be almost as suicidal as trying to take away their kids.
Wish her fun shooting with whatever she decides on. Take her to a range and let her try out a bunch of different ones, then buy her the one she likes. You can offer, you can suggest, but this has to be HER decision alone.
She just might surprise you. (My ex shot my BUNS off in a match once, and we were using the same gun! Try explaining THAT to the guys over coffee!)
