How about a S&W 99 in .40 cal? Knock down, concealable, pursable. good point shooter, and, depending upon her hand size (this is a thing-Rita, that's the wife-carries a S&W 99 or a Glock, depending on how she's dressed,......but she's not a "petite" gal at all.....:lol:
Besides, how can you go wrong with a James Bond gun like the 99????? :lol:
Just be aware they're no longer in production, so repairs in the future may be problematic.
