There’s also safe ways to do everything, like don’t point it at someone, point slightly upstage so it appears you’re pointing at them from the camera angle, for instance. Or not having live rounds on set.
Or, y’know, requiring the actors to become familiar with their real gun and double check safety before they use their real guns (a 15min lesson) because redundancy saves lives (the problem with that is actors pretend they’re too stupid to learn 15min of safety procedures before doing dangerous things and they would prefer to do dangerous things without fully understanding them. I think that’s a bad idea, personally. If I’m using a real chainsaw in a movie I’m gonna learn how to not chop off my own fucking leg as a part of learning my lines, because I like my legs. Same for if you pass me a blank firing gun, a real bullet in the mag turns that into a grenade in my hand, best fucking believe I’m checking, I like my hands!)
