The post you are replying to explained why that is looking at the problem from the wrong direction. The set safety procedures are intended to prevent any actor handling a lethal weapon in the first place, whether it's a light sabre, a hand grenade, stick of dynamite or whatever. The fact that in this case the prop was supposed to look like a loaded gun without really being one, and that on a gun range there are procedures to safely accept real guns seems to be a red herring.
What if the prop had been a stick of dynamite with a lit fuse? Or a car, which might potentially have faulty brakes or innumerable other unsafe parts?
Do you think there should be mandatory cuts for safety checks every time one movie character picks up a gun or hands a gun to another character?
I think that when a movie character picks up a gun that character should, in character and as part of the movie, follow the safe procedure and provide a check of the gun before doing anything else with it. Likewise a character who receives a gun from another character. Then a whole lot more gun nuts who love violent movies would be exposed to procedures that they are likely not aware of. A small number might even learn something from it.
The "set safety procedures" are proven to be inadequate. Additional procedures are required.
