Doesn't this gun appear in a fictional variant form in Killzone 2? http://i165.photobucket.com/albums/u76/Edizzle8002/killzonesmg11fu2.jpg
Judging from the reciever and sights, it looks more like some Uzi with the grip moved back and a helical magazine whacked in. Kinda ugly IMO.

The Tokarev version with the curved mag and the 10-round .380 ACP mag are at the bottom of the first post. Evil Tim 07:18, 17 June 2011 (CDT)
Vityaz is a derivative of Izhmash PP-19 Bizon, it differs only in replacing of a helical-feed magazine with a more common stick magazine. I think that Vityaz must be merged into Bizon page which in turn be renamed into "Izhmash PP-19" with subheaders "PP-19 Bizon" and "PP-19-01 Vityaz". Greg-Z (talk) 22:03, 19 February 2014 (EST)
