With those figures, 132,695 large frame top break Smith and Wesson's stayed in the US, and most of those were probably west of the Mississippi. I'd say they were very popular...
Anyone know how many Colt 1873 SAA were produced before 1900ish? IIRC< it was around 150,000. Another under rated revolver on the Frontier were the cartridge conversions of Colt, Remington, and others. If truth be told, and I remember from the McDowel Book, there were probably 150,000 conversions. That would make the 1873 about one in every three pistols on the frontier.
I have two .44-40 SAA clones (a Thunderer 4 3/4" and a nickel 4 3/4"), two 1871 Open Tops, and one 1870 Russian top break.
