In law and order and other crime TV shows, they silence guns by shooting through e empty soda bottles or baby bottle nipples. I don’t see why most killers would care about sound though, because even if the shot is heard, by the time people get to the scene, the shooter is gone.
My favorite is the potato silencer. They just cut a small indentation into the spud and press it onto the muzzle - presto. I remember seeing Richard Roundtree do that in an old episode of Shaft, silencing a .30-06 bolt-action hunting rifle to BB gun sound levels.
Totally realistic < rolls eyes >.
empty soda bottles.....With small caliber rifles and small caliber auto’s you are correct.
