# PP-91 Kedr

The PP-91 Kedr is a 9mm machine pistol developed from a prototype from the 1970s and since 1994 adopted by the Russian Ministry of Internal Affairs.

## Overview

The PP-91 is a simply designed, easy to manufacture selective fire submachine gun designed by Yevgeny Dragunov (the designer of the SVD sniper rifle).
It is blowback operated and fires from a closed bolt, allowing for more accurate shooting than would be possible from an open bolt design. Ammunition is fed from a double column box magazine and it is supplied with folding shoulder stock.
Despite the small caliber of the round it uses, the notable advantages of the PP-91 are its compact size and the weight of only 1.5 kg, making it very easy to carry, and can be fired effectively by only one hand. The safety/selector lever is located on the right hand side and allows for semi-automatic single shots and fully automatic fire at the rate of 800 rounds per minute. The effective range of the PP-91 is between 50-100m. The weapon uses a diopter sight and allows for the use of a laser sight and a suppressor.
