Stupid gun mistake
It always surprises me when film and TV-show makers spend so much money to get the sets, costumes, and actors to look “just right”, then they make a stupid mistake.
Whenever you watch a show where somebody uses a revolver with a silencer, (like Cheech Marin the bartender), it’s a huge screw-up.
Revolvers can’t be silenced because there is a gap in the rear between the cylinder and the hammer, and a gap in the front between the cylinder and the barrel. A lot of noise from the explosion escapes through these gaps when a revolver is fired.
