kriss vector super v recoil system

The KRISS Vector was first designed in 2006 by a formly known company Transformational Defense Industries (TDI).

This weapon system is designed to be a rapid firing submachine with its unique Super V downward recoil mechanism to reduce perceived recoil and muzzle climb.

Other than its unique design, the weapon system is extremely easy to field strip by only using 4 push pins for maintenance, and it uses Glock magazines.

Available first for 45 ACP, now it has evolved to GEN 2, chambered for 9mm, 40SW and 357 Sig.
