According to my source, There were a little over 310,000 Colt Single Actions made through the end of production at the beginning of WWII, plus another 46,240 target and Bisley models, most of which were plain Bisleys. about 158,000 were in .45, or about 45%. Of the rest, the .44-40 was produced in the greatest quantity with about 71,400 manufactured. The vast majority of the rest were either .38-40 and .32-20 but 19,750 were produced in .41 Colt. It was produced in 29 different calibers, or more correctly, calibers with 29 different names, some of which I've never heard of.
Ever heard of .44 German?
Shoot low, sheriff. They're riding Shetlands!
Underneath the starry flag, civilize 'em with a Krag,
and return us to our own beloved homes!
