For sheer functionality, I picked the Glock (19). Sure there's prettier, but in 9mm, it's the smallest, lightest "Wondernine" I know of, and it goes bang when trigger is pulled.
I don't have much use for a 9mm, but when I picked what I considered to be the BEST all around choice for my wife when I'm not home late at night, I firmly settled upon the Glock 19 with a 15 round mag and +2 baseplate... 18 rounds of 9mm in a gun that fits her hand fine, doesn't weigh a lot, isn't too awefully big.......
