Revolver

A revolver or six-shooter (as most revolvers have a maximum capacity of six rounds) is a repeating firearm that has a cylinder containing multiple chambers and at least one barrel for firing. The first true revolver—a flintlock—was made by Elisha Collier in 1814. The percussion cap revolver was invented by Samuel Colt in 1836. This weapon became known as the Colt Paterson. The first cartridge revolvers were produced around 1856 by Smith and Wesson. Though the original name was "revolving gun", the short-form "revolver" is universally used.
