The Lancaster Pistol was a multi-barrelled (either 2 or 4 barrels) handgun produced in England in the mid-late 19th century,[1] chambered in a variety of centrefire pistol calibres—chiefly .380", .450 Adams, .455 Webley, and .577 calibre.[2] Sometimes classified as a Howdah pistol, the Lancaster pistol enjoyed popularity with British officers in India and Africa during the British Raj owing to its faster rate of fire and increased reliability over contemporary revolvers.
