Have you checked out the CZ Rami? There's a poly version, but it's also available with the aluminum frame. Just a thought. Can I ask why you're not interested in a poly frame?
Edit: I failed to mentioned the Stoeger Cougar 9mm that I own (on the left in the picture). My girlfriend picked it out. She's a small framed woman herself but she seemed to like guns that filled her hands more than the smaller framed guns. This gun looks great, feels great and has performed flawlessly for us thus far. Just another recommendation.
