How about the smith and wesson 659 in Reservoir Dogs...Man, makes me want to get one, pick up a black suit, white shirt, a shoulder holster, a pack of smokes, wayfarers and listen to little green bag by the george baker selection....
I still cant believe someone mentioned the Howard the Duck movie! from what I remember, that was an awesome movie. But that was 20 yrs ago and I was a early teen!
