The Webley Mk III is a British revolver that was introduced in 1947. It is part of the Webley family of firearms and was designed primarily for military and police use. The revolver is chambered for the .38 S&W cartridge and features a double-action mechanism, allowing for quick firing. The Webley Mk III has a distinctive design with a solid frame and a swing-out cylinder for easy reloading. It was widely used by British forces and law enforcement agencies until it was eventually replaced by more modern sidearms. Its robust construction and reliability made it a favored choice during its service years.
