A Technical Problem
***Minor Spoiler***
The scene in the sauna when the main character uses a revolver with a silencer (more accurately called a sound suppressor) to kill a man seems to be a 'goof'.
-Stupid Gun Mistakes EVERY Writer Makes
"THE SILENCED REVOLVER If you're dumb enough to put a silencer on a revolver then you'll discover that all the noise you hoped to suppress will escape from around the cylinder. A revolver is not sealed. There's a gap between the cylinder and the barrel where they meet. This gap allows the cylinder to turn. It also allows gas and noise to escape."
