The third issue of the Model is known as the "Model Single Action Revolver". It differs substantially from the first two issues by breaking at the top (just in front of the hammer), consistent with the design of the Safety Hammerless or S&W .38 Single Action. It can be readily distinguished from the first two issues by its lack of ejector rod under the barrel, the large hinge in front of, and just below the barrel, and the extractor that ejects spent cartridges when the barrel is hinged downward. The grip is rounded at the butt, and is similar in appearance to that on the 2nd Issue. This revolver marked the debut of the .32 S&W centerfire cartridge.
