TT-33

The TT-33 was intended to replace the obsolete Nagant M1895 revolver, but production was never sufficient to fully replace the vast number of revolvers already in service. The TT-33 is chambered in 7.62x25mm Tokarev, which is based on the 7.63x25mm Mauser round of the Mauser C96 (which had been widely used by Bolshevik forces during the Russian Civil War) but loaded to higher pressure levels.

The basic TT-33 has no safety of any kind, but pistols imported to the US after the Gun Control Act of 1968 require a "positive manually operated safety device" under ATF Form 4590, and so all such guns will have an aftermarket safety added.
