I just watched another news story about this horrible event. I am no expert, however, I have a lot of experience with firearms. I heard that 2 people were shot. This movie set is for a western. so that tells me that the handguns were revolvers. I would expect the revolver to be a black powder revolver that has to be pre loaded and caps need to be placed on the rear of the cylinder, and the weapon is a single action revolver that requires the hammer to be pulled back before each shot can be fired, and the same is true if it was a revolver similar to a trap door revolver, which you load through the 'trap door' at the rear of the cylinder, with an encased bullet... like the one's we all know. I believe these handguns back then were also single action... so tell me???? after the first round was fired, and you realize you just sent a live round down range... What tells you to crank off another round? I welcome any and all corrections on what I posted. B.T.W. I own 2 single action revolvers, and they are "Modern" relatively speaking... Jojo
