   The PP-19 Bizon (bison) is a Russian submachine gun, developed in the early 1990s. It was first publicly revealed in 1993. It is based on the Kalashnikov AKS-74U compact assault rifle and has high degree of parts commonality. This submachine gun has been adopted by the Russian law enforcement forces. Some sources report that production commenced in 1996. Overall it proved to be a rather unsuccessful design, produced only in limited numbers.

   The Bizon uses up to 60% of components from AKS-74U compact assault rifle. It is actually built on the shortened received of the AKS-74U. Such commonality of parts allowed to simplify production and reduce development and production costs. However the Bizon is a submachine gun, rather than a compact assault rifle. It is a blowback operated weapon, which fires from an open bolt. Unlike the AKS-74U it has got no gas system, so internal components have been redesigned accordingly.

   The Bizon is chambered for 9x18 mm Makarov ammunition. The 9x18 mm round was the standard pistol and submachine gun round in the Soviet Union and Warsaw Pact countries. However it is less powerful and looses in terms of penetration to the standard 9x19 mm Parabellum round.

   This submachine gun uses the same trigger and safety mechanisms of the AKS-74U assault rifle. The selector level has three positions for "safe", "semi-auto", and "full-auto".

   Unusual feature of this weapon is that it is fed from detachable high-capacity helical magazines. Design of these magazines was copied from American Calico designs. The Bizon magazine holds 64 rounds. It serves as a forearm during firing. This weapon has got a lot of firepower.

   The Bizon has got a skeletal metal buttstock of the AKS-74U. The buttstock folds to the left. A foregrip is made of synthetic materials. Pistol grip is also similar to that of the AKS-74U.

   The original Bizon has got simple iron sights from the AKS-74U. However later production models come with slightly different AK-74 style iron sights. This weapon has a side-mounting rail, that can mount various scopes. Range of effective fire is up to 100 m using standard ammunition and up to 150 m using improved armor-piercing ammunition.

   The Bizon can be equipped with a PBS-1 detachable silencer.




   Bizon-2 is an improved production version. This weapon has got a longer barrel and slightly different AK-74 style iron sights with settings for 50, 100 and 150 meters. Some versions of the Bizon-2 have a sighting range of 200 meters. Newer versions of the Bizon-2 have a different skeletal metal buttstock, which folds over the top of the weapon. There are versions of the Bizon-2 submachine gun, chambered in 9x18 mm, 9x19 mm, 9x17 mm (.380 ACP), and 7.62x25 mm Tokarev ammunition. Also there are several semi-automatic only variants of the Bizon-2, intended for civil market. There is a version with integral silencer.

   Bizon-3 is a further improved version with some modifications. It has a skeletal metal buttstock, which folds over the top of the weapon.

   Vityaz PP-19-01 Vityaz is a Russian submachine gun, that evolved from the Bizon design. This weapon was developed to meet requirement of the "Vityaz" elite anti-terrorist unit. Hence the name of this weapon. It is also based on Kalashnikov AKS-74U compact assault rifle, but has a more conventional appearance. It is chambered for 9x19 Parabellum ammunition, which is now is standard in Russia. It is fed from traditional curved 30-round magazines. The Vityaz has been adopted by the Russian police and law enforcement forces. It seems that Vityaz is produced in larger numbers than the Bizon.
