Wildbill may be fast, but he prestaged his moonclip for easy grabbing, did anyone else see him reach in his pocket to set the moonclip up to be able to grab it quicker. He also had a firing grip on his gun before the fellow tossed the thing in the air. Not quite the even contest he presents it as.
I will give him he is fast and smooth in doing the reload
After shooting his waves the pistol around with no regard for muzzle control and at the end of the video appears to sweep the muzzle in front of his friend. It is no matter if the arm was empty or not, It was just lousy gun handling. Of course that is just my professional opinion.
