The PP-19 Bizon is a Submachine gun which was Designed  in the year of 1993-1995 by two Engineers Victor Kalashnikov & Alexi Dragunov.The Bizon is a lightweight selective fire weapon that fires from a closed bolt, a feature that enhances the gun's accuracy.It is based on the AKS-74 and features a 60% parts commonality with the assault rifle.Chambered for the standard Russian 9x18mm Makarov pistol cartridge, the gun will also fire a new high-impulse armor-piercing 57-N-181SM round.

The Bizon uses a simple straight blowback method of operation, an unlocked breech system reduces cost and build complexity. The Bizon's operating cycle is characterized by a very short recoil stroke, standard 9x18mm ammunition will only drive the bolt partially to the rear of the receiver and produces a cyclic rate of 700 rounds/min.High-impulse ammunition forces the bolt to travel all the way to the end of the receiver, barely striking the receiver wall. A rate of fire of 650–680 rounds/min is the result. This has the effect of reducing perceived recoil and increasing controllability and hit probability.

The Bizon has no gas system and the internal components have been modified accordingly. The bolt carrier with integral charging handle was recycled from the AK, however the piston rod and rotary bolt were removed and the piston extension was plugged with a steel insert.The return spring and guide rod are identical to those of the AK.

 hinge-like action required to seat the magazine.

One of the Bizon's more unusual features is the magazine, which is often confused for a grenade launcher.The cylinder below the barrel is in fact a 64-round helical-feed magazine, similar to the type used in the American Calico M960 submachine gun.The magazine is made from a durable glass-reinforced polyamide and mounts under the handguard in line with the barrel. This layout makes the weapon more compact and concealable.
