What is the intended use of a revolver’s rotating cylinder?

The intended use of a revolver's rotating cylinder is to hold multiple rounds for firing. This design feature allows a revolver to have a capacity for several cartridges, typically ranging from five to eight, depending on the model. When the shooter pulls the trigger, the cylinder rotates to align a fresh cartridge with the barrel, enabling sequential shots without the need to reload after each shot. This mechanism is key to the functionality of a revolver, as it allows for quick successive firing without requiring the shooter to manually load each round individually.

Other elements, such as aiming precision, firearm stabilization, or cartridge ejection, are not the primary functions of the rotating cylinder, making them less relevant in comparison to the core purpose of housing ammunition.
