What does the cylinder in a revolver primarily serve as?

The cylinder in a revolver primarily serves as storage for ammunition. Unlike semi-automatic pistols, which utilize a magazine to hold cartridges, a revolver features a revolving cylinder that holds multiple rounds. When the revolver is fired, the cylinder rotates to align a fresh cartridge with the barrel for each shot. This design allows the shooter to fire several rounds before needing to reload.

Understanding this design is crucial for handling a revolver safely and effectively, as it impacts how one should manage ammunition and reloads during both practice and live shooting situations. The cylinder's function as ammunition storage is essential for the revolver to operate, making it a fundamental component of the firearm's action.
