The KRISS Vector Gen 3 SDP (Special Duty Pistol) in .45 ACP with Arctic Delta Cerakote finish delivers the lightest and most agile member of the Vector family in a premium two-tone coating that combines distinctive aesthetics with enhanced protection. This compact, versatile platform proves ideal for personal protection and home defense while chambering the proven .45 ACP cartridge for maximum stopping power. The revolutionary Super V Recoil Mitigation System redirects recoil forces downward rather than backward, dramatically reducing muzzle rise and enabling rapid follow-up shots with the hard-hitting .45 ACP cartridge. Combined with the world's lowest bore axis-positioned in line with the shooter's second knuckle-the Vector SDP provides mechanical advantage over recoil forces that conventional .45 ACP pistols cannot match. The fully redesigned Gen 3 upper and lower housings provide enhanced ergonomics, improved hand support, and expanded customization options. Compatible with full-size Glock .45 ACP magazines, the SDP delivers intuitive handling and seamless magazine interchangeability. At just 5.6 lbs and 15.35 inches overall length, this is the most compact Vector configuration available with big-bore defensive power. Ships with one 30-round magazine, cleaning kit, cable lock, user manual, and warranty card. Arctic Delta Cerakote Finish The Arctic Delta finish features premium Cerakote coating in a distinctive two-tone pattern that provides both exceptional corrosion resistance and eye-catching aesthetics. Cerakote's ceramic-based formula delivers superior protection against wear, chemicals, and environmental exposure compared to traditional finishes. The Arctic Delta colorway combines contrasting tones that create a unique appearance while maintaining low-glare characteristics suitable for defensive use. Patented Super V Recoil Mitigation System The KRISS Vector's revolutionary Super V System is a delayed blowback operating system featuring a small bolt carrier group connected to a low-mass slider guided by channels in the frame that run perpendicular to the barrel. As the bolt cycles, the system redirects recoil energy downward rather than straight back into the shooter's hands. This downward-directed energy becomes a counterweight to the barrel's natural tendency to rise when fired. With .45 ACP's substantial recoil energy, this patented system transforms what would be a difficult-to-control pistol into an exceptionally flat-shooting defensive platform. World's Lowest Bore Axis The Vector features the lowest bore axis of any firearm in the world. The barrel is situated below the fire control group, positioned in line with the second knuckle of the dominant hand rather than high above it as with conventional pistol designs. This placement gives the operator mechanical advantage over recoil forces, as the recoil impulse pushes straight back through the hand rather than creating a lever arm that rotates the muzzle upward. With .45 ACP's powerful recoil impulse, this design advantage delivers flat shooting characteristics that keep sights on target. .45 ACP Defensive Power Chambered in .45 ACP, the Vector SDP delivers proven manstopping power with the time-tested cartridge trusted for over a century. The .45 ACP's 230-grain projectile at 850+ fps from the 5.5-inch barrel provides substantial energy transfer and penetration, making the Vector SDP exceptionally effective for defensive applications where immediate incapacitation is critical. Ultra-Compact Pistol Configuration The 5.5-inch barrel and pistol format with no stock deliver just 15.35 inches overall length and 5.6 lbs weight, making the SDP exceptionally maneuverable in confined spaces. This compact footprint excels for home defense, vehicle deployment, and personal protection scenarios. The pistol configuration also enables use with arm braces (sold separately) for enhanced stability without NFA requirements. Gen 3 Enhanced Ergonomics The fully redesigned Gen 3 upper and lower housings provide enhanced ergonomics with improved hand support positioning and refined grip angles. The Gen 3 upper supports aftermarket pistol grips, providing customization options to match shooter preferences and hand size. Glock Magazine Compatibility The Vector SDP accepts full-size Glock .45 ACP magazines, ensuring reliable feeding with proven magazine designs. This compatibility provides flexibility with capacity options and eliminates proprietary magazine concerns. Ships with one 30-round magazine for extended defensive capabilities. 4140 Chrome Moly Barrel with Black Nitride Finish The 5.5-inch barrel is machined from 4140 chrome moly steel and treated with QPQ black nitride finish for exceptional corrosion resistance and wear characteristics. The barrel features .578x28 right-hand threading for suppressor or muzzle device attachment. Pivoting Single-Stage Trigger The pivoting single-stage trigger provides consistent pull characteristics and clean break for accurate shot placement. The trigger design accommodates the Vector's unique fire control group positioning below the barrel. The KRISS Vector SDP Gen 3 in .45 ACP with Arctic Delta Cerakote finish combines revolutionary recoil control, proven stopping power, and premium aesthetics in an ultra-compact defensive package.
