Thanks guys. A NP22 or Nork 1911 in 9mm was what I was thinking of. Single stack is a must.
She has held and fired all of mine, and tried a few others, so I have a sense of what she prefers.
I think the M&P is a good choice (she has shot my .40), but I want her to do her BB and learn the basics with a hammer fired, external safety (and no mag safety) pistol. I think that is a better foundation, and a little simpler to understand the basics.
My SP01 is plenty heavy, and she has a hard time racking the slide (the recoil springs in those are dogs).
She'll likely need an extended mag release anyway.
