Magnum's Biggest Finest Revolver, the first and only revolver ever offered by Magnum Research, is carefully crafted in the U.S.A. This all-stainless steel revolver is built to close tolerances to handle the pressure of true big-bore calibers - .45/70, .480 Ruger/.475 Linebaugh, .450 Marlin, and .45 Long Colt/.410(not for sale in CA) - as well as .454 Casull, and the unique .22 Hornet.
