The TT-30, commonly known simply as the Tokarev, is an out-of-production Soviet semi-automatic pistol. It was developed in 1930 by Fedor Tokarev as a service pistol for the Soviet military to replace the Nagant M1895 revolver that had been in use since the Russian Empire, 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. Romania produced a TT-33 copy as the TTC, or Tokarev Cugir well into the 1950s. These have been made available for commercial sale in great numbers in recent years. Here is a prime example, as Rangeview Sports is looking to sell off a bunch of these.
