I was given a Ruger Blachawk .357 magnum with an extra 9mm cylinder that states on the box that it was hand-fitted from the factory for this revolver. They both have the stated required last three digits of the serial number printed on both cylinders. This was my dad's gun and he said that he never used the other cylinder that he received when it was new. Is this common and is it safe to shoot with 9mm?
