How a Chiappa Rhino Revolver Works

Wikipedia: The Chiappa Rhino is a revolver produced by Italian manufacturer Chiappa Firearms. The Rhino's frame is CNC-machined from a solid block of high-tensile aluminium alloy and all internal parts are CNC-machined from steel. Chambered for the .357 Magnum/.38 Special, 9mm Parabellum, .40 S&W, or 9×21mm cartridges, its most distinctive feature is that the barrel is on a much lower bore axis, as the Rhino fires from the lowermost chamber of the cylinder rather than from the topmost chamber in conventional revolvers.
