Not OP, buuut ...
If the cylinder is out, or the slide / bolt is back, with no magazine, and a view of the chamber that clearly shows that it's not loaded then you're ok to treat it like a normal object - otherwise you could never clean or inspect a gun properly
Or the safety is on ... or in my favourite gag related to this, in My Spy where all the bullets fall out of the bottom of the magazine when the trigger is pressed
