why so many 9mm guns in movies/tv

[MT2008]

I was mostly referring to the scene where he bangs his GF in the middle of Chinatown, especially while a whole bus full of naive Chinese schoolgirls were watching. I can't remember the last time I laughed so hard at a sex scene in a movie.

As far as gunplay goes, it was neat seeing the Springfield XD in action. So far, this is the first movie or TV show in which I've seen that gun appear.
