This is a new Taylors & Company/Uberti 1873 Gunfighter (555165DE) single action revolver chambered for .357 Magnum. This gorgeous pistol features a nickel finish, and 5.5" barrel. It includes a box, manual and softcase.

From Taylors:

The Gunfighter Nickel model is the perfect solution for any shooter looking for more grip to hold on to. Taylor's installed the favorite 1860 Army grip onto the new model frame cattleman to accommodate the larger hand shooter. The Army grip is longer and slightly wider than the smaller Navy grip that is usually found on 1873 single action models. Features a nickel plated forged steel frame, nickel plated parts, and a smooth Army Size walnut grip. The Taylor Tuned Gunfighter Nickel comes ready to shoot out of the box featuring a hand polished action and our custom springs. Taylor's gunsmiths custom tune guns specifically for each order.
