The Chiappa Rhino is a revolver produced by Chiappa Firearms of Italy. The frame is CNC machined from a solid block of high tensile aluminum and all internal parts are CNC machined from steel.
Chambered for the .357 Magnum, its most distinctive feature is that the barrel is on a low axis compared to other revolvers. The Rhino fires from the lowermost chamber of the cylinder, rather than firing from the topmost chamber.
In order to reduce weight, the frame of the Rhino is made of Ergal (an aluminum alloy), The Rhinos receiver is CNC machined from a solid block of high tensile aluminum. Virtually all of the components are CNC machined as well; this manufacturing process yields a very precise fit with minimal tolerances. For models other than the 20D (double action only), the trigger may be used in either single-action or double-action mode. Only the 2 inch 20D model comes in "double-action only".
The external cocking lever is not actually a hammer, as on most revolvers. Instead, it is used to cock the internal hammer and then falls back into place, minimizing the number of externally moving parts and reciprocating mass, making the revolver different internally. An additional feature of this gun is that, unlike most revolvers, it comes with an accessory rail (except for the 2" model), on which lights and lasers can be mounted. The Aluminum alloy based revolver is available in anodized finishes resembling traditional blued, as well as a version resembling electroless nickel finish referred as the "White Rhino."
Unusual among revolvers, the Rhino fires from the lowermost chamber in the cylinder as opposed to the uppermost. This is intended to reduce muzzle flip by directing the recoil into the shooter's wrist, rather than over it. Another distinctive feature is that the cross-section of the cylinder is hexagonal instead of cylindrical (though with rounded corners); this is intended to lower the weapon's profile in concealed carry applications.
