Unfortunately they've been discontinued, but the Beretta Model 85 Cheetah .380 sounds about perfect since she'd never have to rack the slide. Its an 8 shot single stack with a "tip up" barrel like the .25ACP Jet-Fire. OTOH to me, being blow back, the recoil is worse than the 9mm 92, but to my wife its not, I think its the lower muzzle blast from the full sized .380 vs. the blast from the supersonic 9mm rounds in the 92.
Another suggestion, take a look at the SIG P238 its small size enhances recoil, but being locked breech the recoil spring is among the lightest I have. What would help the most is that she could split the slide racking force into two halves by manually cocking the hammer, apply the safety, and then rack the slide to chamber a round.
The "gas retarded blow back" of the 9mm Walther CCP was supposed to address the issue, but when I looked at one it seemed to me when the striker was un-cocked it was harder to rack than the P380 with the hammer back. The Walter P380 is bigger than the SIG P238 and would let her split the slide racking force in the same way, but I won't recommend it because my friend has one and he hates it despite being a huge Walter fan -- says its the most inaccurate gun he's ever owned.
