Interestingly enough there is a second goon that has his hands cupped to look like he's holding a handgun of some sort, though his hands are actually empty. Richard apparently didn't have enough guns to share

The next shot in the trailer shows him holding a 92FS instead. One of Dave's chicks also carries one in Richard's underground bunker.

A Daewoo K3 is used by the Postal Dude (Zack Ward) for two shootouts. He manages to get out of both of the sizely shootouts unscathed and with one hundred percent casualties on his aggressors.
