The remaining shots were fired by working the hammers in the same way, and the actions caused an up-and-down movement of the guns.

Seems a funny way to fire a revolver, doesn't it?
But it wasn't funny for the man who was in front of the bad man.
He had another way of not leveling the gun at all, but firing from his hip, the revolver being held there, and the hammer worked with the thumb.

Another and very expert way was to fire from the holster, not taking the gun out at all.

This was remarkably quick and deadly.
But the strangest way of all, that was sometimes used at close quarters, was called "fanning." The gun was held at the hip, the first shot fired with the thumb-hammer movement.

The gunman spread out the thumb and fingers of his other hand, and quickly drawing them across the hammer, one after another, they fired the shots with lightning rapidity.
