In addition, wise students of quick-draw for combat shooting seldom practice drawing and firing a loaded double-action revolver or automatic at top speed. They draw and dry fire an empty gun at top speed, but draw and shoot a loaded gun at a significantly slower speed. On the few occasions when an experienced shooter does practice a maximum-speed quick-draw with a revolver, he generally loads five rounds of ammunition into the six-shot cylinder, so that the first time he pulls the trigger, the hammer will fall on an empty chamber. If he screws up the draw, the sound of the hammer falling on the empty chamber while the gun is still in the holster will generally be enough to stop him from pulling the trigger again, firing a loaded cartridge into his leg the second time. And the wise practitioner uses a firmly anchored quick-draw-holster, which will release the gun very easily, whether it be a belt holster or a concealment rig.
