Remington Army Model and Colt 1861 Army models and later pistols are on a smaller frame, and use a lighter powder charge. The last of the US horse pistols are the "Dragoon", which was made by Colt and several other companies. One of the rarest is a iron framed Dragoon bad by a Civil War armory in Texas, 100 made, 3 known to still exist!
The south also used a French revolver called the LeMatt that was huge, 9 shot 40 caliber plus a 16 gauge smooth bore in the center. The gun was big but the revolver charge was only 19 grains of FFFg. Most went to cavalry units (probably less than 500) Some went to the CSN, and at least one CSA General carried one on his waist!!
Springfield Arsenal made the single shot 58 cal., true horse pistol until the late 1840's-early 1850's. I'm sure there are many contractor provided pistols from the Revolution on! I agree Flayderman's is the best easy source of info and there are prices based on condition (while now worthless for real value, they give an idea about how one condition values to another!)
All of my large Colts, Remingtons and LeMatts are repros and not worth viewing in this context.
