The TT-30 is a Russian semi-automatic pistol. It was developed in the early 1930s by Fedor Tokarev as a service pistol for the Soviet military to replace the Nagant M1895 revolver that had been in use since Tsarist times, though it ended up being used in conjunction with rather than replacing the M1895. It served until 1952, when it was replaced by the Makarov pistol.
In 1930, the Revolutionary Military Council approved a resolution to test new small arms to replace its aging Nagant M1895 revolvers. During these tests, on January 7, 1931, the potential of a pistol designed by Fedor Tokarev was noted. A few weeks later, 1,000 TT-30s were ordered for troop trials, and the pistol was adopted for service in the Red Army. But even as the TT-30 was being put into production, design changes were made to simplify manufacturing. Minor changes to the barrel, disconnector, trigger and frame were implemented, the most notable ones being the omission of the removable backstrap and changes to the full-circumference locking lugs. This redesigned pistol was the TT-33. Most TT-33s were issued to officers. The TT-33 was widely used by Soviet troops during World War II, but did not completely replace the Nagant.
