The Kriss Vector 22 SDP refers to a variant of the Kriss Vector platform chambered in .22LR (Long Rifle). The "SDP" stands for "Special Duty Pistol," indicating that it is designed as a compact pistol variant. It maintains the Kriss Super V System to reduce recoil and enhance control. Resembling the original Kriss Vector, it features a short barrel, a stabilizing brace or folding stock, and Picatinny rails for accessories. Designed to replicate the Kriss Vector experience using cost-effective .22LR ammunition, it's ideal for enthusiasts seeking a lower-cost caliber for practice and training.
