The military in the CW did not issue pouches for carrying spare cylinders. The issued pistol cartridge box was designed to carry prepackaged packets of paper cartridges. It is not nearly wide enough to accept a cylinder.
In preparing inventory for my Sutlery, I study lots of period procurement and issue documents. Never recall seeing a mention of cylinder pouches. Never saw an original at CW collector shows. So they carried them in their pockets right? Civil war cavalry jackets and the common “sack” or fatigue coat that often replaced them had no exterior pockets.
I have followed this thread for months. The extra cylinder supporters seem to rely on the logic that I would have done it, so they must have done it 160 years ago. But you are a civilian with disposable income. These guys were soldiers who carried what they were issued, and the army didn’t issue extra cylinders. And at $13 a month, they were lucky to be able to purchase the overpriced tobacco and canned peaches from their regimental Sutler. This assumes they were even available to purchase them as Colt was tied up with military contracts. My comments are limited to soldiers as civilians could do whatever they wanted, and could afford. But with the 1849 pocket pistol being colt’s most popular civilian product, it seems the average civilian placed a priority on ease of carry/ concealment, just as today.
it is possible that a few officers could have provided themselves with extra cylinder(s), as they were required to purchase their own weapons and uniforms. But this would be the exception and not normal or common for cavalry as a whole. Interesting, while regulations required officers to equip themselves with a sword, Carrying a pistol was optional.
I am not going to discuss extra pistols in this post, except to ask, has anyone seen a military issue holster designed for left side butt forward wear to balance the issue right side butt forward holster? The cavalry belt can only carry so much gear, but the horse,, the military quit issuing pommel holsters before the Civil War began.
