At a LGS the owner was inspecting a customers 1911. He racked the slide several times without looking in the chamber and assumed the weapon was clear. He pulled the trigger and unleashed a 230gr FMJ into the shop wall which ricocheted off the wall and struck one of his employees in the stomach.
He has a nasty scar but he is alive. At least the owner had it pointed in a "safe" direction rather than pointed directly at him. The results may have been even worse.
