The 5.8ÃÂ21mm DAP92 (, ) is a Chinese rimless, bottlenecked, centerfire cartridge designed as an armor-piercing PDW ammunition for handguns and submachine guns.
The cartridge was designed to replace the 7.62ÃÂ25mm 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 9ÃÂ19mm Parabellum round.
This round is offered in both a standard and subsonic version. Both the QSZ-92 service pistol and the QCW-05 submachine gun are produced in this caliber as well as 9ÃÂ19mm Parabellum.
