The KRISS Vector features is a delayed blowback, closed bolt sub-machine gun featuring a revolutionary Super-V bolt mechanic which directs the bolt downwards when cycling massively reducing recoil when fired fully automatic. Chambered in 9×19mm, 40 S&W, 10mm and .357 the variant in the game fires the .45 ACP round the weapon was originally designed around.
The .45 ACP round provides a higher damage per round than the 9x19mm MP5 and MPX, but has a greatly reduced magazine capacity of 13, which can be increased to 25 with an extended magazine.
The addition of a tactical stock and foregrip increases stability at short to medium range.
