An improved version of 1st Model. Most notable difference is larger diameter trigger pivot pin and frame protrusions above trigger to accommodate it. Front sight blade on this model is made of steel instead of nickel silver. Several internal improvements were also incorporated into this model. This model commonly known as American 2nd Model. The 8" barrel length was standard. Approximately 20,735 manufactured between 1872 and 1874. NOTE: There have been 5.5", 6", 6.5" and 7" barrels noted; but they are extremely scarce and would bring a 40 percent premium over standard 8" model. Use caution when purchasing these short barrel revolvers. Approximately 3,014 chambered for .44 Henry rimfire with large triangular flat-tip firing pin, may bring 10% to 25% premium.
