PP-19 Bizon - WikiHQ

The PP-19 Bizon (, Pistolet Pulemyot Bizon, Pistol Submachine Gun "Bison") is a 9×18mm Makarov submachine gun developed in 1993 by the Russian company Izhmash.

History

The Bizon was designed by a team of engineers headed by Victor Kalashnikov (son of engineer Mikhail Kalashnikov, creator of the AK-47) and including Alexei Dragunov (youngest son of Yevgeny Dragunov, the creator of the SVD sniper rifle).

Victor called the Bizon "The Woman's Gun" due to it being light with no recoil.

The Bizon was developed at the request of the Russian Ministry of Internal Affairs (MVD)

Chambered for the standard Russian 9×18mm Makarov pistol cartridge, the gun will also fire a new high-impulse armor-piercing 57-N-181SM round.

Operating mechanism

The Bizon uses a simple straight blowback method of operation; an unlocked breech system reduces cost and build complexity.

High-impulse ammunition drives the bolt all the way to the end of the receiver, lightly striking the receiver wall.

A rate of fire of 700–750 rounds per minute is the result. Due to the slow cyclic rate, it has the effect of reducing perceived recoil and increasing firing stability and hit probability. The handguard is a sheet metal stamping with three rounded rectangular ventilation slots on each side.

The magazine serves as the lower handguard and the current models of the magazine are ribbed to enhance grip. The Bizon also uses the same trigger and safety mechanisms as the AK-74 rifle.

Some magazines were produced with indicator holes allowing the user to verify the amount of ammunition loaded; these are spaced at 4, 24, 44 and 64-round increments.

Bizon-3

A variant known as the Bizon-3 was also developed and features a flip-up rear peep sight moved further to the rear on the receiver cover and a stock that folds up and over the receiver to lock into a spring-loaded latch on the receiver top cover.

The weapon's barrel has an adapter for several types of muzzle devices. These are selected by the operator depending on the weapon's tactical employment and include sound suppressors, muzzle brakes, compensators, and flash hiders.

Derivatives

The SN9P features modifications such as a Galil-style stock to suit local conditions, with limited use by Special Forces units.

SN7P

Vietnamese Bizon clone chambered for 7.62x25mm, also manufactured by the Z111 Factory.

Service

The Bizon is issued to armed response units of the Federal Security Service (FSB) and Ministry of Justice in Russia.

It was used in combat operations against separatists in the North Caucasus region, namely Chechnya and Dagestan.

The Bizon has been largely replaced by the PP-19-01 Vityaz in Russian service, which was developed directly from the design of the Bizon, due to reliability issues with the helical magazine.
