The Webley Revolver is a type of firearm that was widely used by the British military and police from the late 19th century into the 20th century. Known for its distinctive top-break design, it allows for quick reloading by breaking open the frame. The revolver typically fires .455 caliber cartridges, making it powerful and effective for its time. Developed by Webley & Scott, the revolver became iconic during both World Wars and was favored for its reliability and ease of use. Various models were produced, including the Webley Mk VI, which served as the standard-issue sidearm for British forces until the 1960s.
