In the final shootout, Books fires his belly gun four times, before he drops it, and his holster gun three times. The two nearly simultaneous shots through Sweeney's table are so fast, they have to be one from each pistol. After Gillom takes the holster gun and fires it three times at the bartender, it should be empty. But as he prepares to throw the gun away, it is obvious there are still loaded rounds in at least two chambers.
