Is AnnaLynne McCord the Female 'Dirty Harry'?

Who knew sexy Annalynne McCord is just as comfortable playing an on-screen siren as she is wielding a six shooter?

"I'm from Atlanta. You can take the girl out of the south, but you can't take the south out of the girl," the 90210 vixen said Saturday in Las Vegas while celebrating the launch of the Fallout: New Vegas video game. "I like to shoot guns."

The 23-year-old safe shooter even has her eye on a particular model to call her own: a Colt M1911 with a handle made from Mother of Pearl. One thing she won't be doing with it though is shooting live targets.

"I like to shoot targets that are not living," McCord said at the party at Rain Nightclub of sticking to shooting ranges and target practice. "Unless they're on a video game, then I don't mind spreading some blood."
