KRISS Vector SDP .45 ACP SDP 5.5inch threaded LH

Experience one of the most innovative developments in modern firearms technology with the patented KRISS Vector Platform. 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 by 60% and muzzle climb by 95% when compared to traditional operating systems.

The KRISS Vector GEN II is the next evolution of the Vector platform, taking it from a firearm into a multi-caliber weapon system.  Chambered in .45ACP and 9mm (Coming October, 2015), the KRISS Vector is compatible with the ubiquitous Glock magazine.  Changing between calibers can be done in seconds, without any tools.  The KRISS Vector GEN II is more ergonomic with a redesigned trigger, a short throw ambidextrous safety lever, and a more comfortable pistol grip.

The KRISS Vector SDP is the Non-NFA semi-automatic pistol variant of the KRISS Vector platform. It features a short, threaded, 5.5” barrel. A rear quick detach sling point assists with carrying the firearm. Additional standard equipment on the KRISS Vector SDP are the Magpul MBUS sights, full length picatinny top rail and a Glock Magazine.  Although this SDP maybe small, it still has the same capabilities as its larger counterparts and is civilian legal in most states.

The SDP is available with either a 5.5” or 6.5” threaded or non-threaded barrel.
