Cullen Bohannon (Anson Mount) continues to use a Colt 1860 Army as his primary sidearm in "Viva La Mexico" (S2E01) as he did for much of the first season. However, after he is captured, and subsequently released by the US Army, he switches to a Remington 1858 New Army for the remainder of the season. Some of the former Confederate soldiers-turned-train-robbers also use the Colt 1860 Army, including Hawkins (Ryan Robbins). US Cavalry soldiers also use the Colt 1860 Army revolver during the season. Gregory Toole (Duncan Ollerenshaw) also uses a one in "Blood Moon" (S2E09). The 1860 was the most common handgun in the United States at the time, most had a brass trigger guard (see photo), they were not originally manufactured with a brass frame.
Elam Ferguson (Common) carries a Colt 1860 (Richards-Mason Conversion) revolver with an 8" barrel as his sidearm throughout the season.
The Richards-Mason Conversion revolver is the most common loading gate conversion for the Colt 1860 Army. Is noted from Richards conversion by sights located on hammer, much like the original design.
In "The Railroad Job" (S2E05), fallen gunmen still holding their revolers. These appear to be brass-framed copies of the Colt 1851 Navy revolver, which did not exist until the Italians started making them during the 1960s.

Rifles
Sharps 1874
In "Scabs" (S2E04), Bohannon uses a a "long rifle" to shoot a railroad worker tortured by the Sioux. The rifle seen appears to be a Sharps 1874 fitted with a Malcolm-style scope, which is again a problem of dating since the railroad was completed in 1869 and the 1874 model came . . . well . . . later.
