Only two members here post, and then call their comments a "trade secret". That answer makes the point. I really don't have to. But nothing wrong with a little cheese to go with the whining 🤣
Good stuff SDave. Thanks for making the effort to check the 1907 .45 ammo in a SAA.
did anyone even consider, in 1913 to 1915, that these cylinders are black powder components?
I have to agree...."probably not".
I'd going as far as to say, "I'd bet they didn't even consider as an issue". Looking back in history to at least the '20s (and much later up to the '40s by the antidotal evidence) 45 Colt smokeless ammo simply wasn't easily available and when it was it was, it was a lot more expensive that BP. More than twice the price if you could find smokeless 45 Colt or 44-40. The world had few liabilities, less Government oversight, fewer lawyers, no seat belts, and an economy fully driven by capitalism. The idea was to make a $, not throw away "good parts" from a gun, that was long dead, 10 years prior to 1915.
There was still a market for the SAA in 1915, and none for the M1878.
Caliber production of the LF guns:
965 produced in .45.
28 in .44 Special.
207 in .38-40
110 in .32-20.
By 1910 all were all three easily available in smokeless, if I am to believe my vintage catalogs. All of those calibers have stronger cylinders in a SAA that a 45 Colt or a 44-40. I have to wonder if that was an intentional choice by Colt. Again, I'd bet it an intentional choice on their part.
Funny enough smokeless 45 Colt ammo was not easily available as one might have thought in 1915. Twice the price in the Winchester catalog BP verses smokeless. And smokeless 45 Colt ammo simply not listed in the Sears and Roebuck catalog. Of course 45 Colt BP ammo was listed there.
What I found in the two vintage ammo catalogs is telling for anyone willing to look. There were a LOT
of changes happening when the US was still using a good deal of BP ammo, while the rest of the world was already fully engaged with smokeless ammo in almost all their common calibers. The takeaway from the research I did was this, "Smokeless ammo came to the newest rifle calibers pretty quickly, after 1895 in the US. The same was not true of pistol calibers. It took new guns, starting with the M1892, then the Colt 1905 Colt Semi Auto pistol with 45acp smokeless ammo (which eventually ended with the Colt 1911 design and ammo) and then the 1907 Colt dbl action revolver using a smokeless "45 Colt cartridge" smokeless, with its limitations. By 1892 (the Colt M1892) if was obvious the SAA was an obsolete design. DBL action revolvers and semi auto handguns would soon dominate the marketplace.
A good bit of my comments are pure conjecture on my part, "an educated guess", nothing more. No secret there.
