The Remington-Rider Single Shot Derringer Parlor Pistol was made by E. Remington and Sons between 1860 and 1863.

[1] It is the smallest Remington Pistol ever made and was produced for only three years; the total estimated production quantity is less than two hundred.

Not made for use with powder propellants, this diminutive sidearm launches 4.3 mm projectiles at surprisingly high velocities with the use of a percussion cap only.

The frame, grips, and 3-inch barrel were integrally constructed of sand-cast brass.

There are two types of breech-pieces, about equal in frequency in existing production guns; all known prototypes have the one-piece design, which provides no cover to enclose the cap, and its locking lever is quite short.
