As a woman... she prob'ly has more need for a gun for self defense than you do.
Forget the 'pink' crap. These aren't fashion statements to be 'cute'... 'n nobody'd want a 'pink' gun anyway if she sold it on an upgrade later on. Best bet would be a DA wheelgun in at least .38 or .357 snub nose. Original 'point and click' interface. Get some Hogge or Pachmyer grips on it 'cause the snubbies kick a bit much for their grip size.
