The Type 68 is a North Korean hybrid of the Tokarev and the High Power, used as a military service pistol until replaced by the Beak-Du-San copy pop the CZ75. The general outline of the gun is a copy of the Tokarev, with a modular removable fire control group, lack of manual safety, and tall thin sights. It is chambered for 7.62x25mm, and uses a magazine identical to the standard Tokarev except for not having a magazine catch cut, as the Type 68 has a heel magazine release.
Internally, the High Power elements include a detent-retained barrel pin, use of a solid barrel cam instead of a 1911/Tokarev swinging link, and a fixed barrel bushing. Two patterns of markings exist, one with a date and North Korean marking, and one (like this example) with only a serial number.
North Korean guns of all types are very rare in the United States. A very small number of Type 68s have come into the US, generally through Central America (probably via Cuba) and South Africa (via Rhodesia/Zimbabwe).
Update: It appears that the original design work for these was done by an independent engineering firm in Yugoslavia. The design (a TT33 with High Power type locking and angled slide serrations) was not completed in time for the trials that would lead to adoption of the Yugoslav M57, and the drawings were transferred to “another country” – probably North Korea.
Thanks to Legacy Collectibles for loaning me this pistol for filming!
