It is notable for being the model of firearm used by John Hinckley Jr. to shoot Ronald Reagan on 30 March 1981.
The Gun Control Act of 1968 prevented their import unto the US, so subsequently they were manufactured at a Röhm factory in Miami.
The RG-14 is known colloquially as a Saturday night special, a general category of cheap, low quality handguns.
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.
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.
