This comment seems a little strange: semi-automatic pistols have ejectors, since the force of the quickly burning gunpowder forces back the action, which ejects the used shell casing and, on its return forward, pushed a new cartridge into the chamber from the magazine below. Revolvers do not have such ejectors, and spent shell casings remain in the cylinder until manually ejected when one swings open the cylinder and removes the spent cartridge casings. After firing a few shots, the shooter would have no reason to empty the cylinder.
