Some women are not into the subject so much that they will do any research. I know my wife isn't. Therefore, I did the research based on some answers to my questions that she gave me. I narrowed it down to 3 guns. We went to the LGS and she decided herself among them. Her final reason? She liked the shiny one. But I knew all 3 would work for her so her reason didn't really matter. At least she likes her gun.
Something very important should be the trigger system and the safeties involved. Is she really going to practice enough to be able to deal with DA/SA triggers or decockers?
I really like the Kahr 9mm's, especially the CM9/PM9. It recoils a lot less than the physics says it should. The trigger is DAO and very consistent. If that size feels a bit small, consider the P9/CW9, which is just a little larger.
