The KRISS Vector GEN II is the next evolution of the Vector platform, taking it from a firearm into a multi-caliber weapon system and is compatible with the ubiquitous Glock magazine. At the heart of each Vector is the Super V Recoil Mitigation System. This unique operating system redirects energy down, and away from the shooter, which eliminates felt recoil and muzzle climb. Changing between calibers can be done in seconds, without any tools. The SDP is the semi-automatic pistol variant of the KRISS Vector platform. It features a short, threaded, 5.5” barrel. The frame is made of polymer composite and advanced metal components that make it both lightweight and durable. A rear quick detach sling point assists with carrying the firearm. Additional standard equipment on the KRISS Vector SDP includes: Magpul MBUS sights, a full-length Picatinny top rail, a lower Picatinny accessory rail, an ambidextrous safety, and a smooth pivoting trigger with both audible and tactile reset. This model comes with a stabilizing brace and ships with one 17-round G17 magazine.
