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

Constructed from stamped sheet steel, it weighs in near 3.5 lb. 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 150–300 ft. The weapon uses a diopter sight and allows for the use of a laser sight and a suppressor.
