Overview

The Type 79 is China's first indigenously-designed submachine gun, certified in 1979 and entering mass production in 1981. Designed by Liu Zhitong, it is highly unusual among SMGs in using a gas-operated short-stroke piston with a rotating closed bolt - a system more typical of assault rifles - rather than the simple blowback action that nearly all other 1970s-era SMGs employed. It fires the 7.62x25mm Tokarev cartridge (Chinese Type 51) from a 20-round detachable box magazine, with a side-folding stamped steel skeleton stock.

Notes

Originally developed for jungle warfare during the Sino-Vietnamese conflicts but found greater success with Chinese police and Armed Police units, where its accuracy in semi-auto is well-suited to urban hostage-rescue work. Replaced in PLA service by the simpler blowback Type 85 from 1985.

Background

The Type 79 is one of the only submachine guns ever fielded that uses a gas-piston rotating-bolt action - a system designed for high-pressure rifle rounds. Engineers borrowed it directly from the Type 56 (Chinese AK-47) in the misguided belief that more parts commonality with the standard rifle would simplify training and supply, but the resulting SMG was complicated, expensive, and ironically replaced four years later by the dirt-simple blowback Type 85.
