S&W 1871 AMERICAN MODEL GRIPS
This was first revolver to use the Dodge and King patents combining a hinged frame with simultaneous ejection of the fired cases. Originally bulky and clumsy, the design has since been refined over the years to become standard system for any top-break revolver. The six-shot .44 S&W was also the first large-caliber revolver to be designed from the outset for metallic cartridges. It had a ribbed barrel and was available in blue or nickle finish.
