Movies imply over and over, that pretty much everybody in the old west carried a Colt .45 Long Colt Single Action Army in 4 or 5 inch barrel. A few exceptional people like Matt Dillon, Max Sand, Jack Paladin, Shane etc. along with the Cavalry carried the 7 inch. Everything else was Colt 4 and 5 inch. John Wayne, Montgomery Cliff, John Ireland, Clint Eastwood, James Stewart, Henry Fonda, Glenn Ford, Richard Widmark, Robert Taylor, Erroll Flynn, etc. etc. carried Colt 4 or 5 inch Colt SAA. (even in movies and tv that take place prior to 1873. My favorite is The Comancheros with John Wayne that takes place in 1847, LOL!!!)
Well, obviously this wasn't entirely the case. A lot of men carried converted 1851s Navys, 1860 Army's, 1858 Remingtons as well as new 1873 Colts, Schofields, 1875 Remingtons, etc in .38 LC, .38 SC, 41 LC, .44-40, .45 LC, .45 Schofield etc. etc.
I understand a lot of men, like the Texas Rangers, prefered the Colt 1873 SAA (don't know what barrel) in .44-40 because it matched their Winchester lever actions.
Sooo......were Colt SAAs really that common?
