One of many firearms developed for Remington by Joseph Rider was the Rider Magazine Pistol - a manually operated 5-shot repeater chambered for the .32 extra-short rimfire cartridge (the same round used by the Chicago Palm Protector). It used a tube magazine under the barrel and a simple but clever vertically shifting breechblock to give an impressive amount of firepower in small (and particularly flat and narrow) package. About 15,000 of these were made between 1871 and 1888, and they represent one of the few American uses of a tube magazine in a handgun - a combination more popular in Austria (and which was instrumental in the development of semiautomatic handguns there).
