Design
The cartridge was designed to replace the 7.62×25mm Tokarev chambered small arms for the People's Liberation Army, and be able to pierce soft body armour while still offering a wound as large as a standard 9×19mm Parabellum round.[2]
This round is offered in both a standard and subsonic version.[1] Both the QSZ-92 service pistol and the QCW-05 submachine gun are produced in this caliber as well as 9×19mm Parabellum.[3][4]
