Last I saw, they had proven the gun could be discharged without touching the trigger. They also use dummy rounds in revolvers to make it look like the gun has real rounds instead of blanks (cheaper than CGI and less likely to miss one), the only way to tell they aren’t real is to remove each round and shake them as they have rattles. I don’t expect an actor to be an expert in firearms, just like I don’t expect them to be experts on politics or climate change.
