The PP-19-01 "Vityaz" is a recent development of the Izhevsk Mechanical Plant (IZHMASH); this weapon evolved from relatively unsuccessful PP-19 "Bizon" submachine gunon request from elite Russian law enforcement team "Vytyaz" (SWAT-type formation). Like its predecessor, PP-19-01 is based on the AKS-74U compact assault rifle, with simple blowback action, although "Vityaz" (Knightin Russian) uses more conventional box magazines and fires more powerful 9×19 ammunition which is now standard in Russia. As of mid-2007, PP-19-01 is in limited production in Izhevsk and is already in use by some specialized SWAT-type OMON teams of Russian police and other law enforcement agencies. The PP-19-01 "Vityaz" can firemost commercially-available 9×19 Luger/Parabellum or 9mm NATOammunition, as well as Russian issue 7N21 armor piercing ammunition.
The PP-19-01 "Vityaz" is based on AKS-74U compact assault rifleand shares about 70% of parts with the parten weapon. The bolt system is of simple blowback type, 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. PP-19-01 utilises AKS-74U-style side-folding skeletonized butt and tangent-type adjustable rear sight. Left side ofreceiver is fitted with Russian-standard side rail that will acceptquick-detachable scope mounts with various sighting equipment. A modifiied version of PP-19-01 (Vityaz-SN) is available with additional Picatinny style acessory rails, left-side charging handle and additional safety lever on the left side of receiver.
