I know nothing about guns, but I’ve been reading other sources that seem to contradict your absolute statements: 1. This was a period western and could have been using older single action revolvers that have fewer modern safety mechanisms to avoid accidental discharge. From quora: “ With many single action (cowboy) revolvers, the hammer does rest on a cartridge beneath it. They will fire if they land on the hammer. For those, you leave one chamber empty and keep that one underneath the hammer. That makes them completely safe, too.” 2. Are blanks uniform in amount of gunpowder? Not sure what happens today but I read that in the Crow incident they were overloading blanks with more than the typical amount of gunpowder to overemphasize the muzzle flashes. 3. While your points about gun safety are reasonable, this appears to not be how it is done in movie sets. The armorer is specifically in charge of safety checking all guns repeatedly. Not the actor.
