The MP-412 revolver has been designed at IZHMECH (State-owned Russian Izhevsk Mechanical Plant, a large factory known as a prime maker of Makarov PM pistols among other things). This revolver was intended for export, as a handgun ownership is generally prohibited for ordinary citizens in Russia. First prototypes of REX (Revolver for EXport) revolver were displayed at IWA-2000 arms exhibition in Nurenberg (Germany). It is not exactly known what killed this rather interesting project, but most possibly it was a lack of market, as the biggest export market, the USA, has been closed for Russian handguns since mid-1990s, because of Clinton / Yeltsyn mutual agreement.
The MP-412 is a double action revolver with break-open frame and simultaneous extraction. The bottom frame is of composite type – it consists of a steel basic frame and a polymer envelope, which forms the grip and trigger guard. Polymer grip / trigger guard unit can be removed from steel frame if necessary. Trigger is of conventional type, double / single action, with exposed hammer. Firing pin is mounted in the frame. Barrel / cylinder group latch is located at the top rear of the frame, and is operated by two buttons that must be pushed inwards to unlock the frame. Cylinder holds 6 rounds and has an automatic ejector that throws the cases out of cylinder once barrel is fully tipped down. If necessary, automatic ejection feature can be manually switched off.
