In the early 1950s Röhm GmbH of Sontheim/Brenz, which was traditionally focused on the production of chucking tools, diversifys its product line and started to produce alarm guns, flare guns and handguns. Röhm's product line of firearms was primarily established under the brand name "RG". In 2010 the management of the Röhm GmbH decided to sell the complete manufacture of firearms to the UMAREX GmbH & Co. KG of Arnsberg and to refocus on its core market of chucking tools.
Police Officer Thomas Delahanty was shot by John Hinckley, Jr. with a Röhm revolver during his failed assassination attempt on Ronald Reagan. Delahanty later sued Röhm with the argument that small, cheap guns have no purpose except for crime, and thus that the company should be held responsible. The suit was subsequently rejected by the District of Columbia Court of Appeals in a suit that has served as case law for other similar product liability cases.[1]
