Joseph Rider(Remington) 1871

This is the palm-sized repeating pistol Remington produced after the Derringer(M95).
While the Derringer held 2 rounds, this model features a 5 rounds tubular magazine, allowing the pistol to hold a total of 7 rounds.

Unlike the Marius Berger's pistol, this pistol is single-action, but its mechanism is very similar.
