What distinguishes a revolver from other firearm types?

The defining characteristic of a revolver that sets it apart from other types of firearms is the presence of a rotating cylinder. This cylinder holds multiple chambers, each capable of containing a cartridge. When the shooter pulls the trigger, the cylinder rotates to align a fresh chamber with the barrel, allowing the firing pin to strike the primer and discharge the round. This mechanism is distinctly different from other firearm types, such as semi-automatic pistols, which typically use a magazine to feed rounds into the chamber, and shotguns or rifles that may operate on pump, bolt, or lever actions. The rotating cylinder of the revolver not only allows for multiple shots to be fired in succession but also gives it a unique aesthetic and operational complexity compared to firearms that rely on a single chamber or magazine feeding systems.
