I wonder how many "senior level history students," become such because they cannot cope with mathematics? In a discussion of the Colt SAA, you wish to put the time frame 100 years before WWI? That would make it 1814, which was 59 years before the SAA's release. Prior indeed to the widespread advent of any revolver? Colt's first revolver, called the Paterson, and a much different animal from the later SAA was still 22 years in the future.
At any rate, I think that the original question, if asked in a somewhat more informed manner might have been phrased thus: "Would a man, in 1874, armed with a Colt's Single Action Army revolver have been at a disadvantage, when compared to the other sidearms available at the time?" The answer is a resounding NO.
There wasn't much competition in the power field, as the only revolver more powerful at the time was the '47 Walker Colt, of which only 1100 were made. The walker was powerful, but hugely massive, unreliable, and used cap 'n' ball loading, rather than cartridges, also the low production figures indicate that it wasn't the most available thing, either. .45 Colt, or .44-40, either chambering oustrips just about anything else that was widely available.
Rate of Fire wasn't much of an issue, as the SAA is still the fastest cycling pistol around, when in expert hands, for the first 5 or six shots. 1911 can't touch it, nor can a Glock, (even the G18, or so I've heard) or the DA of your choice. S&W's Schofield, which was the SAA's contemporary is far slower.
Reliability was either superior or far superior to anything else available. The earlier percussion revolvers were prone to all manner of problems, such as falling loading levers, wet powder, exploded caps locking the actions, powder fouling doing the same, chain fires, the list goes on. The few DA revolvers around at the time were very delicate little creatures, unlike the rugged SAA. Again, the SAA wins over the Schofield, as the Smith was a much more complex design, and also was prone to the top break breaking open at inopportune moments. I've witnessed this at a SASS match, buzzer goes off, Schofield user draws, and the hinge pops open, ejecting his shells on the ground. Not good, if your hollywood showdown opponent has a Colt, while you're trying to pick up your bullets that just fell on the ground, he's launching his at you.
The only place that the SAA doesn't really shine today is in the time it takes to reload. But in 1874, its only competition would have been the cap 'n' ball 1858 Remington, or the Schofield. The Remmie wins, provided you have spare cylinders loaded, and on hand. Could use about like a modern speedloader. The Schofield is also a touch faster, as it ejects all shells simultaneously, rather than one at a time. However, a practiced hand can unload and reload a SAA in about 9-12 seconds.
The only major failing with the SAA design was the safety notch. It was intended to be fully loaded, and carried with the hammer on the so called safety notch, i.e. the first of the four clicks. However, that notch in the hammer was prone to breakage, which allowed the hammer to fall a short distance to a live primer. Together with whatever force broke the notch in the first place, this usually resulted in an accidental discharge. As such, the only safe way to carry a SAA is with the hammer down on an empty chamber.
Otherwise, you might find yourself with a case of Glock leg. Oops, I meant Colt leg, really, I did.
