The PP-2000 is designed as a close-quarter combat weapon, intended for riot police and special operations forces.

[7] The PP-2000 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.

One unusual feature is the ability to store a spare 44-round magazine at the rear of the gun, where it also functions as a stock.

Another unusual feature is that this firearm's charging handle is located directly behind the front sight and folds out of the way when not in use.
