To expect every handler of a firearm to be knowledgeable enough about guns to safely unload, confirm what ammunition is in use, and then proceed accordingly when they also have to act and deal with what comes with that is insane.
Fuck that, absolutely not, every single handler of any firearm is required to know how to safely unload and confirm that it is unloaded. Period. End of story. If you don't know how to drop the mag and rack the slide then don't fucking touch that thing. Guns aren't toys, and they aren't props. The armorer is there for guidance and for double checking but there should never, ever, for any reason other than a survival emergency, be a gun in the hand of someone who does not know how it functions. Not for actors, not for cops, not for civilians. It takes less than a minute to confirm an unloading and it takes 15 minutes to teach someone how who has never seen a firearm before. There is no excuse whatsoever (BIG EDIT: assuming a competent armorer, that can actually teach this) for an actor not knowing how to confirm their own gun is ready for scene, and the armorer should check it themselves immediately before or after, before the scene starts.
Korpiklaaani's cover of Ievan Polkka goes absolutely insanely hard
Yes, that's the only thing I know about them
I've also recently discovered Brothers of Metal who despite having the most boring metal band name in history are a pretty good nordic/viking metal band, I'm a big fan of Powersnake by them in particular recently
