Ditto to the idea of a Sig 238. I think I'm starting to sound like a fanboy and I those types usually annoy me. So at the risk of annoying myself, I'll strongly suggest having her try out a P238. The HD model is heavier, but negates recoil even more if weight isn't a huge deal.
They're incredibly accurate and ergonomic for most, reliable and come standard with tritium sights now (if that matters to you).
The lack recoil of my P238HD is hard to believe. I took my Polish P64 to the range the same day as my P238HD once for kicks. Holy cow, try that someday and you'd think the P238 is imbued with some supernatural recoil reduction.
My wife can rack the slide just fine. If the hammer is retracted first, I'm think anyone who has use of their arms and digits could chamber a round.
The P238 is single action only and is anything but inexpensive. However, if you can find a proper rig and stomach the premium, you cannot find a better pistol in the caliber, IMHO.
