KRISS Vector
Produced by Kriss USA, Inc.
The KRISS Vector is a submachine gun developed by the American company KRISS USA, formerly Transformational Defense Industries (TDI). Civilian variants in semi-automatic only configuration are also available. Designed in 2006 and seeing limited production since 2009, the KRISS Vector uses an unconventional delayed blowback system combined with in-line design to reduce perceived recoil and muzzle climb, invented by French engineer Renaud Kerbrat. The KRISS Vector is designed to accept extended Glock magazines and fires a variety of pistol cartridges.
