Why not a PPK in .32acp if she finds the .380 too much for her? Or the Sig 232 in .380 which is slightly larger than the PPK which manages recoil much better IMO, especially with the Hogue rubber grip.
The PPK though is a blowback design, along with the Sig 232. Because of it being a blowback vs a locked breech design it generally has more felt recoil.
You could have her check out Ruger's new LC380, not to be confused with the LCP. It is an LC9 chambered in .380.
