In Chapter 9, at the 36:00 mark, Wax and Reece are in a shootout with the security members of a drug kingpin. When it is down to Reece, Wax, and one last gunman, Reece rolls a 357 magnum revolver across the table to Wax, and Wax kills the gunman with it. When Wax shoots the gunman, we hear a shell casing hit the ground thereafter. However, revolvers do not eject shell casings.
