Fedor Vasilevich Tokarev developed the TT-30 Pistol for the Soviet Military. The TT-33 (Tokarev-Tula) adopted in 1933, an improved design over the TT-30, was widely used by Soviet troops during WWII.
A very close, less polished facsimile of John Browning's 1911 automatic pistol in design and function with a much simpler hammer/sear assembly.
Production of the TT-33 in the USSR stopped in 1954. Also made by China as the Type 51, Type 54, and M20, Hungary as the 48 M, Egypt as the Tokagypt 58, North Korean as the Type 68. At one time or another most communist or Soviet block countries made a variation of the TT-33 pistol.
