The Vietnamese used the Type 54 during the Vietnam War, with the designation súng ng?n K-54 (a Vietnamese translation from the Chinese 54 (type 54 hand gun), with K for Ki?u being type). Though the QSZ-92 (Type 92) has supplemented the Type 54 in the Army, the weapon is still in service in some of the Chinese armed forces (such as the People's Armed Police and some People's Liberation Army troops) today. This type of pistol is commonly available in 7.62×25mm caliber, although some variants have been made in 9×19mm Parabellum. In 1954, after approximately 250,000 pistols were manufactured, the designation was changed to Type 54 and the pistol used exclusively indigenous components. The Type 51 was first adopted in 1951 and produced in Shenyang's Factory 66 using both Soviet and Chinese-made parts. The Type 54 is the improved version of the Type 51 (Chinese copy of the TT-33) produced after the Korean War. Type 54 pistols are also known colloquially as "Black Star" pistols ( Traditional Chinese:?, Simplified Chinese) due to the five-pointed star engraved on its all-black grip panel. The Type 54 ( simplified Chinese: 54 traditional Chinese: 54) and its variants ( Type 51, M20, TU-90 and Model 213 pistols) are Chinese copies of the Soviet type Tokarev TT-33.
