The Cimarron 1872 Open Top Navy is a reproduction of the historic Colt Open Top revolver, representing a transitional design between the 1851 Navy percussion revolver and the later Single Action Army. Chambered in .38 Special, this single-action revolver features a distinctive open-top frame design with no top strap, characteristic of early Colt cartridge conversions. The revolver features a 7.5" barrel (also available in other lengths), blued finish, and traditional brass trigger guard and backstrap. The six-shot cylinder loads through a rear loading gate, and like other single-action revolvers, requires manual cocking of the hammer for each shot. The 1872 Open Top Navy maintains historical accuracy with its period-correct features including the unique "Navy" style grip frame, one-piece walnut grips, and traditional front blade sight with rear sight notch cut into the hammer. Notable features include the original-style barrel wedge retention system, traditional four-click hammer action, and period-correct timing mechanisms. The revolver's construction combines authentic details with modern manufacturing techniques, resulting in a reliable reproduction that captures the essence of this historically significant transitional design. The combination of the open-top frame, longer barrel, and Navy-sized grip frame makes this model particularly interesting to collectors and enthusiasts of early cartridge conversion revolvers.
