The 7ET9 submachine gun is in development by the state-owned TASCO corporation of Ukraine. Apparently it is based on the unsuccessful prototype Elf-2 submachine gun, developed during mid-1990s by questionable and now-defunct KB-ST organization. Unlike the prototype, the 7ET9 returned to simple design and more or less realistic characteristics. It is fairy typical submachine gun of conventional design; originally developed for more or less obsolete 7.62x25 TT cartridge, it was also developed into 9x19 version, known as 7ET10. According to available information both versions are still not completely developed and neither is being manufactured so far. Very little proven and factual information is available on this design, so description below may have some speculations and assumptions rather than facts.
