This is a Chiappa Firearms DA/SA known as the Rhino chambered in 357 Magnum, model 340.290.
The Rhino is the most innovative development in revolver technology in decades" if not since the creation of the revolver itself. Refusing to be constrained by tradition and previous design limitations" the Rhino has improvements that move the revolver forward into the 21st century. Unconventional in appearance and superior by performance" the Rhino fires from the bottom of the cylinder rather than the top. This dramatically reduces muzzle rise and recoil felt by lowering the axis of the bore almost to the palm of the shooter's hand. An aluminum alloy frame and barrel shroud make the Rhino lightweight and easy to carry.
