The 5.8×21mm cartridge is a Chinese armor-piercing firearm cartridge. The cartridge was designed for replacements of 7.62×25mm Tokarev–chambered small arms for the People's Liberation Army that would offer a wound as large as a standard 9×19mm Parabellum round. This round is offered in both a standard, and subsonic version.〔 Both the QSZ-92 pistol and the QCW-05 Type 05 submachine gun are produced in this caliber as well as 9×19mm Parabellum. The 5.8×21mm is slightly less powerful than similar Western rounds, like the 5.7×28mm and 4.6×30mm. It has a steel-cored bullet that has a muzzle velocity of and muzzle energy of from a submachine gun barrel. The round can penetrate of helmet steel plate, and of pine wood behind it, out to 100 meters.〔(Where Next For PDWs? by Anthony G Williams )〕 ==See also== * 4.38×30mm Libra * 4.6×30mm * 5.7×28mm * 5.45×18mm * 5 mm caliber 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「5.8×21mm DAP92」の詳細全文を読む スポンサード リンク
