The Type 54 (simplified Chinese: 54式手枪; traditional Chinese: 54式手槍) and its variants (Type 51, M20, TU-90 and Model 213 pistols) are Chinese copies of the Soviet type Tokarev TT-33. Type 54 pistols are also known colloquially as "Black Star" pistols (Traditional Chinese:黑星手槍, Simplified Chinese: 黑星手枪) due to the five-pointed star engraved on its all-black grip panel.
