The .442 Webley is a British centrefire revolver cartridge.

A snubnosed revolver is a small, medium, or large frame revolver with a short barrel, generally less than 4 inches in length. Smaller such revolvers are often made with "bobbed" or "shrouded" hammers and there are also "hammerless" models ; the point is to allow the gun to be drawn with little risk of it snagging on clothing. Since the external movement of the mechanism is minimal or nil, shrouded and hammerless models may be fired from within clothing. The design of these revolvers compromises range and accuracy at a distance in favor of maneuverability and ease of carry and concealment.
