Cold can mean blanks as well.Of course it was a real gun! I guess my explanation was a bit confusing. I was just saying it was announced as a "cold gun" because in SHOULD NOT have had cartridges with gunpowder -- i.e., no bullets or blanks. Only dummy bullets which do not fire, hence cold.
Yet somehow a live bullet got in the mix with the dummy bullets and got loaded. In a closeup shot, the dummies are made to look as authentic as possible. That made checking the gun a little more difficult. I don't own a .45 revolver, but I'd think you'd actually have to remove the cartridges from the chamber to see if they were indeed all dummies?
But in any case.....the armorer should’ve checked it. The assistant should’ve checked it. Baldwin should’ve checked it. Whenever possible, no gun should point at someone....so, the victims shouldn’t have been there. There should be only inert firearms on sets. Just a huge cluster.
