The KRISS USA Vector SDP Enhanced is the Ideal Choice For Home Defense/Personal ProtectionAt the core of the Vector SDP is the Super V Recoil Mitigation System which is a nonlinear, multilink, blowback system which is designed to redirect recoil energy down. If you pair that with the low bore axis you get a massive reduction in felt recoil with an increased follow up shot capability. Additionally the short barrel and compact overall nature of the Vector SDP Enhanced means that you can easily transport and stock your firearm away inconspicuously. The barrel is made from 4140 Chrome Moly material along with a black Nitride Quench Polish Quench finish. As always and like with other Kriss Vector firearms the SDP Enhanced is fed from any full size Glock magazine offering exceptional cross compatibility with a secondary firearm or backup pistol.KRISS USA Vector SDP Enhanced Semi Auto Pistol (Black) Specifications and Features:KRISS USA KV90-PBL30Closed Bolt, Delayed Blowback Semi Automatic Pistol9mm Luger5.5" 4140 Chrome Moly Barrel (Black Nitride QPQ Finish)1:10" Right Hand Twist RateThreaded 1/2x2817 Round MagazineGlock Magazine CompatiblePivoting Single Stage TriggerSuper V Recoil Mitigation SystemLow Bore AxisLow Profile Flip SightsFull Length Picatinny Top RailQuick Detach Sling SwivelOverall Length 16.75"Overall Weight 5.9lbPolymer HousingBlack
