Stop. Just stop. Go back and look at your responses to other´s posts. They´re extremely short, dismissive... dare I even say curt. I don´t know anything about you, so it could be a language barrier thing or something else. But it´s starting to feel like you want to string us all along for some big reveal farther down the line. I would like to give you the benefit of doubt and continue to assume you´re not just a troll. So communication is a two-way street, yeah? Help us out a little here.
This statement is so outlandish as to be ridiculous. My wife´s family were 19th century photographers. We still have a house full of stuff that they used as props in photographs. There are thousands of images of soldiers wearing uniform items they were never issued, like sashes, and holding weapons their units never used, like swords, revolvers and even rifles. There´s an image of a 6th Wisconsin soldier in Lord´s Encyclopedia holding a Mississippi rifle. We know the 6th Wisconsin was not armed with these. Sometimes you´re even lucky enough to see a group of images taken by the same photographer with different men all holding the same props. So, let´s not pursue that any more. I think it´s safe to assume whenever you see a man in an image, that he may be holding a photographer´s prop.
There´s nothing to say that´s not his revolver, either. It might have been. Thousands of them were taken to war by enthusiastic volunteers. Later they were quietly sent home when the soldier realized that the weapon Uncle Sam gave him would do the job just fine. Or a commander ordered them turned in or sent home because of the danger to life and limb that they presented. That particular firearm would be next to useless for an infantryman. It has a range of roughly across the street. It´s too big to carry in your pocket, so it´s going to need a holster.
I think there´s something underneath the elbow of the arm with the pistol. It looks dark and shiny. Chair arm, maybe?
