"Maybe this guy was a famous gun slinger. After all, the other guy drew first, so he must have been very good with a gun."

Rather surreal thread this, considering that nothing like this, ever actually happened in the real "wild west" - no actual recorded instances of any gunfight as depicted in any western ever took place. Of course people got shot, but they were not killed in duel type situations it was just plain murder. For example those shot by Billy the Kid were shot from ambush normally from down an alley and Billy's weapon of choice was a rifle.
