History and design

It was designed in the Soviet Union in the early 1970s by Antonina D. Denisova at the Precision Mechanical Engineering Central Research Institute (TsNIITochmash). The development was done in concert with that of the PSM.[citation needed]

The cartridge is designed to use light spitzer-pointed jacketed bullets.[citation needed]

Variants

  • 5.45×18mm 7N7 (7Н7): spitzer-pointed full metal jacket bullet with steel conical core.[3] The bullet energy is stated to be up to 1.5 times that of .25 ACP in a similar sized cartridge. It is stated to be capable of penetrating 45 layers of Kevlar soft body armor at close distances.[4]
  • 5.45×18mm PSO (ПСО): spitzer-pointed full metal jacket bullet with lead core.[5]
  • 5.45×18mm 7H8 (холостой патрон 7Х8): blank cartridge[citation needed]

Малый калибр, остроконечность и твёрдость пули позволяют ей пробивать мягкие бронежилеты из 45-и слоёв кевларовой ткани... Пуля пистолета обладает весьма низким останавливающим действием"
