The idea of ​​creating such weapons in the caliber 5,45 mm arose under the influence of successful completion of work on submachine gun cartridge of the same caliber.

research, conducted Denisova showed, that stopping action can be obtained with a relatively long and restricted stabilized pool, close to 9mm bullets regular pistol PM. When the corresponding core solid barrier penetrability such bullets is higher. Waste embodiment chuck 5,45h18 MOC (small-caliber pistol central battlefield) with bottle sleeve (after adopting it received index 7N7) These characteristics have been fully confirmed.
