"The Kriss USA Vector SDP Enhanced Gen2 Semi-Auto Pistol continues its reign as one of the most iconic and innovative personal defense weapons in the world. What makes the Vector truly unique is the Super V System a non-linear, multi-link, blowback system that redirects recoil impulse downward instead of rearward. This downward movement of the bolt helps counteract the barrel's tendency to rise during high rates of fire, keeping you on target for follow-up shots. Factor in the Vector's extremely low bore axis (the trigger group is actually above the barrel), and you're looking at one of the easiest-to-control firearms in the world. Even better, the SDP Gen2 Enhanced accepts GLOCK magazines, making it an excellent companion piece a number of GLOCK pistols. Other key features include a 2-stage quick-reset trigger, 6.5"" threaded barrel, QD sling point on the rear, and flip-up sights. Picatinny rails on top of the receiver and on the forend provide space for optics and accessories.
