Ain't gonna tell ya ..... the price of the book is not exorbitant and those truly interested in the arms of the era will be happy to acquire a copy.
I USED to loan out my copies of such books until I had to fight to get them back and then be appalled at the condition they were in upon return. I no longer do that.
I'm not about to regurgitate the many comments and points discussed in Schiffers's book. Taking things out of context rarely works and I think the work deserves to be evaluated in the whole.
You seldom see such a comprehensive effort at reproducing historical conditions, unlike most reviews of repro ACW weaponry. Not satisfied with modern repro bullets, he had several moulds made to original specs, as he did for his earlier book on ACW carbines. He had cartridges made for his Lefaucheux pin fire revolver and modified .32 S&W brass to accept a Flobert blank for the rimfire S&W No. 2 Army.
This latter revolver surprised him with it's 28 yard accuracy, the only distance at which it was fired. Despite it's efficacy for reloading compared to a cap & ball gun, he still regarded it as a "last ditch" weapon. Pity it was not offered in a more serious calibre.
With some revolvers, he was unable to get all the powder into chambers and seat the bullet using supposed historically correct loads without resorting to hammering in bullets or trimming them. Subsequently, velocities were lower than expected.
There are many excellent photos showing many soldiers wearing, posing with various revolvers, including several showing the wearing of regulation-type holsters with the butt facing rearwards. This suggests that they found the regulation butt forward position not as useful.
He also comments on the absence of cartridge pouches in most period photos. Reason - they tended to be worn on the back of the belt as it was unlikely that after firing his revolver empty, the soldier was unlikely to fumble with paper cartridges to reload and cap while under fire in combat. That would have been a real challenge on horseback.
