The PP-19-01 “Vityaz” submachine gun was developed during early 2000s by the IZHMASH (present time “Kalashnikov” concern) factory in Izhevsk; this weapon evolved from relatively unsuccessful PP-19 “Bizon” submachine gun on request from elite Russian law enforcement team “Vytyaz” (SWAT-type formation). Like its predecessor, earliest version of the Vityaz submachine gun was based on the AKS-74U compact assault rifle. By the 2010 the Vityaz was slightly redesigned to use a modified AK-104 receiver as a base, and is now produced in this variant. The PP-19-01 “Vityaz” submachine gun is in use by various Russian law enforcement agencies, and it is also offered for export sales. It can use most types of 9x19mm Luger / Parabellum ammunition, including high-powered Russian loads such as 7N21 and 7N31, which use armor piercing bullets.
The PP-19-01 “Vityaz” submachine gun uses simple blowback action, and gun is fired from closed bolt, ultilising standard AK-type trigger and safety / fire selector subsytems. A special magazine housing is attached below the receiver,which accepts proprietary double-stack magazines, made from polymer. Two magazines can be clipped together using special steel clip forfaster reloading. Vityaz submachine gun utilises AKS-74U-style side-folding skeletonized butt and tangent-type adjustable rear sight. Left side of the receiver is fitted with Russian-standard side rail that will accept quick-detachable scope mounts with various sighting equipment. A modifiied version of PP-19-01, known as the Vityaz-SN submachine gun, is available with additional Picatinny style acessory rails on its hinged top cover.
