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 1871-72 Open Top revolver with an 7.5″ barrel as his sidearm throughout the season. Lily Bell (Dominique McElligott) also uses Elam's revolver to defend against attacking Sioux warriors in "Blood Moon Rising" (S2E10).
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.
Several people use Colt 1851 Navy revolver during the season. Hawkins' (Ryan Robbins) gang members use Colt 1851 Navy revolvers in "The Railroad Job" (S2E05). Most of the revolvers in the series 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.
Thomas Durant (Colm Meaney) sometimes carries a small two-shot Percussion Pocket Pistol on him during the season. Lily Bell (Dominique McElligott) also uses Durant's pocket pistol during the season. Durant gives the pocket pistol to her wife, Hanna Durant (Virginia Madsen) to defend herself when the Sioux attack the town in "Blood Moon Rising" (S2E10).
The Winchester 1866 "Yellow Boy" rifle is used by many characters throughout the series, and Cullen Bohannon (Anson Mount) carries one on his saddle throughout the season. Elam Ferguson (Common) also keeps a Winchester 1866 "Yellow Boy" at his home. Reverend Nathaniel Cole (Tom Noonan) also supplies Sioux warriors with Winchesters in "Purged Away With Blood" (S2E06).
Cullen Bohannon uses a Sharps 1874 rifle fitted with a Malcolm-style scope in "Scabs" (S2E04) to shoot a railroad worker who's being tortured by the Sioux. The rifle is a bit of anachronism, since the season takes place in 1866, and the Sharps rifle was available after 1874.
Thor "The Swede" Gundersen (Christopher Heyerdahl) still keeps his sawed-off double barreled percussion shotgun named "Beauty" around during the season, altough it is rarely seen. Elam Ferguson (Common) also keeps a full-sized double barreled percussion shotgun at his house, and uses it several times as he is patrolling Hell on Wheels as the Chief of Railroad Police. Elam gives the shotgun temporarily to Psalms in "The Railroad Job" (S2E05), who uses it during a shootout. Eva (Robin McLeavy) also uses a sawed-off percussion shotgun to defend Elam's house in "Blood Moon Rising" (S2E10).
