Throw the gun and somehow rig something up such that the trigger is pulled sometime after the gun is thrown. Thus, the bullet is fired from somewhere else while you are in the same place. That's as close to curving the bullet as you're going to get. I'm surprised no one has mentioned DO A BARREL ROLL.
