PP 2000
It is chambered in 9×19mm Parabellum, and specifically designed to utilize the new Russian 9×19mm 7N21 and 7N31 (Cyrillic: 7Н21 and 7Н31) +P+ armor-piercing versions of the cartridge. This is intended to give the PP-2000 armor-piercing capability comparable to the FN P90 and Heckler & Koch MP7 personal defense weapons while also being able to use common 9mm Parabellum rounds.
