Röhm RG-14

A Röhm RG-14 displayed at the Ronald Reagan Presidential Library, similar to the one John Hinckley Jr. used in the attempted assassination of Ronald Reagan.

The Röhm RG-14 is a double-action, six-shot revolver chambered in .22 LR formerly manufactured and sold by Röhm Gesellschaft of Sontheim/Brenz, Germany.

One was used by John Hinckley Jr. to shoot Ronald Reagan on 30 March 1981. The RG-14 is known as a Saturday night special, a general category of cheap, low quality handguns.

The RG-14 was available in a snubnose configuration with a 1.5-inch (3.8 cm) barrel as well as a more typical configuration with a 3-inch (7.6 cm) barrel.

The RG-14 had a swing-out cylinder that was secured to the frame by a pin that passed through its length, rather than a latch under the barrel as commonly found in double-action revolvers. In order to load the weapon, the user had to unscrew and remove the pin, swing the cylinder open and insert a round into each chamber, then snap it shut and screw the pin back into place. The RG-14 also did not have an ejector, meaning that each spent casing or unfired round had to be manually pushed out of the cylinder with the pin or a similar tool during unloading/reloading.
