He's incredibly fast no matter how you look at it, but I'm suspicious he may be cheating a little. Specifically I suspect that he may be hitting the balloons without really aiming using widely scattered unburnt gunpowder. I wonder if he even uses a bullet in his cartridges, or just fires blanks.

@Critic, that would explain why he's using his other hand with the glove the way he does.

Critic, seen him do this on video with real full power loads, also seen him spit a playing card at about the same speed, he is scary fast.

Steve the reason he is "fanning" the hammer with is off/weak hand is that the firearm he is using is a single action revolver and you have to move the hammer back for it to go off. One of the "tricks" he does is use both the leading and trailing edges of his off hand to work the hammer.

Wow. Look at how young he his....

Ed McGivern was pretty fast, too - 10 shots from two .38 spl revolvers in less than a second. All the bullets would fit in the space of a playing card.
