History

The PP-91 Kedr was designed in the early 1970s by designed by Yevgeny Dragunov who was a famous SVD sniper and a weapons designer who also created the SVD Dragunov sniper rifle. Initially, it was called the PP-71 and it was intended to replace the AKS-74U, but it was never adopted by the Soviet military so the project was shelved.

In 1991, the project was “re-discovered” and upgraded. The upgraded version of the gun—the PP-91 Kedr—was put into production by Izhmash, a Russian weapons manufacturer around 1992, and mass production started in 1993. It was issued in limited numbers to certain Russian military units and was also adopted by several law enforcement agencies in Russia.

Soon it was discovered that the ammunition used in the PP-91 Kedr wasn’t powerful enough, so a new variation of the gun – the PP-9 Klin was designed and put into production in 1994. The Klin used the 9×18 PMM ammunition which had much more stopping power than the original.

Overview

The PP-91 Kedr is blowback operated, meaning that when a round is fired, the pressure of the expanding gases pushes the bolt and slides back to eject the spent cartridge casing. The gun also uses a closed bolt position, which means that the bolt is locked in place before firing. This helps to increase accuracy and reduce recoil.

The PP-91 Kedr has a fire selector switch located on the right side of the stamped-steel receiver that allows for semi or full-automatic fire. The ammunition is fed from a double collum detachable box magazine.

Design

The PP-91 Kedr was designed with simplicity and durability in mind. It’s s made out of stamped steel with black oxide coating for added corrosion resistance. It also features a simple top-folding steel stock.

It has a length of 12 inches with the stock folded, 20.2 inches with the stock extended, and a barrel length of 4.7 inches. The gun weighs about 3.4 pounds empty and 4.4 pounds loaded.

The safety and fire mode switcher of the submachine gun is located on the right side of the gun.

The gun is equipped with open diopter sights. The rear blade is L-shaped and automatically flips to the “short-range” setting when the stock is closed and to the “long-range” setting when the stock is opened.

Effective Range 

The PP-91 features a really high rate of fire. The Kedr has a cyclic rate of fire of 800 to 1000 rounds per minute and the Klin variation has a rate of fire between 1050 and 1200 rounds per minute.

The effective range of the PP-91 Kedr is about 50 to 100 meters (164 to 328 feet) and the maximum firing range is about 200 meters (656 feet).

The gun is really accurate as well for a submachine gun.
