The KRISS Vector .45 ACP sub machine gun is not new to SHOT SHOW but it never fails to attract a great deal of attention. This agile SMG features a semiautomatic, two round burst and fully automatic selector with a cyclic rate of about 1200 rounds per minute. In full auto, it doesn’t take long to run through its standard 13-round Glock magazine so KRISS offers an optional 25-round KRISS® MagExtension. The Vector’s compactness combined with the sheer knockdown power of the.45 ACP makes this an ideal protection detail or CQB weapon.
