Revolvers are a type of handgun distinguished by their rotating cylinder, which contains multiple chambers for ammunition. Typically holding between five to eight rounds, revolvers are known for their simplicity, reliability, and ease of use. Unlike semi-automatic pistols, revolvers do not rely on external mechanisms to eject spent cartridges or chamber new ones; instead, the cylinder rotates as the user cocks the hammer or pulls the trigger, positioning a fresh round in line with the barrel.

Revolvers come in two main action types: single-action and double-action. In a single action revolver, the hammer must be manually cocked for each shot, offering a lighter trigger pull and higher accuracy. Double-action revolvers, however, allow the shooter to either cock the hammer manually or fire by simply pulling the trigger, which rotates the cylinder and releases the hammer in one motion, making them quicker to fire in rapid situations.

Favored for their dependability and ease of maintenance, revolvers have been widely used by law enforcement, military personnel, and civilians for self-defense. Their rugged design makes them less prone to jamming, even under adverse conditions. While semi-automatics have gained popularity, revolvers remain a top choice for those who prioritize simplicity and reliability. Available in a variety of calibers and designs, from compact models for concealed carry to larger, high-powered versions for hunting or home defense, revolvers continue to play a significant role in the firearms world.
