The TT-33 was a modification done in 1933 on the TT, or Tokarev Tula, which was manufactured in
1930. With the locking mechanism relatively similar to the 1911, the TT-33 is a recoil-operated,
locked breech pistol. The Tokarev TT-33 was the primary sidearm of the USSR, and was
manufactured by many eastern block countries including China, Yugoslavia, Hungary and North
Korea.
