The cartridge was designed to replace the 7.62×25mm Tokarev-chambered small arms for the People's Liberation Army, while still offering a wound as large as a standard 9×19mm Parabellum round.^[3] 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.^{[citation needed]}
