Except for the new Gen IV, Glocks are a horrible horrible choice for small hands. Now if I were a betting man, I would bet she would really like how an M&P 9 compact will feel. I also agree 100% with Todd on the PF-9 as a good choice, fit great in the hand and are very reliable, just ask the Martin family. But 22 pistols are so much fun, some really great choices given for those.
