Can't see it in the pics, but I am guessing that the captive ramrod has a way to pivot from left to right barrel when in loading mode. Clever!

Used a single barrel officer's pistol of pretty similar design and caliber, a great experience. The captive ramrod once you get used to it eases loading.

Superb pair of pistols. The pair part is fascinating, as they are not of a type that would normally be made as a pair, ie duelling or target pistols.
