KRISS Vector SDP Gen 3 9mm 5.5" Barrel 40rd Glock Mag Compatible Black Semi-Auto Pistol

The KRISS Vector Gen 3 SDP (Special Duty Pistol) delivers the lightest and most agile member of the Vector family in a compact, versatile footprint ideal for personal protection and home defense. 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 unprecedented control. 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 pistols cannot match.

The fully redesigned Gen 3 upper and lower housings provide enhanced ergonomics, improved hand support, and expanded customization options to tailor the platform to any shooter. Compatible with full-size Glock 9mm 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. Ships with one 40-round magazine, cleaning kit, cable lock, user manual, and warranty card.

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, dramatically reducing muzzle climb and enabling the shooter to stay on target through rapid strings of fire. This patented system transforms 9mm into an exceptionally controllable 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. The result is flat shooting characteristics that keep sights on target even during rapid defensive fire.

Ultra-Compact Pistol Configuration

The Vector SDP represents the most compact Vector configuration available. 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 where larger firearms would be cumbersome. 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. These updates improve shooting comfort and control during extended sessions while maintaining the Vector's distinctive appearance. 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 9mm magazines, ensuring reliable feeding with proven magazine designs available worldwide. This compatibility provides flexibility with capacity options and eliminates proprietary magazine concerns. Ships with one 40-round magazine for extended defensive capabilities without reloads.

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 1/2x28 right-hand threading for suppressor or muzzle device attachment, enabling easy addition of sound suppressors or compensators.

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.

Lightest Vector Configuration

At just 5.6 lbs, the Vector SDP represents the lightest configuration in the Vector lineup. This reduced weight enhances maneuverability and reduces fatigue during extended carry or defensive scenarios while maintaining the full benefits of the Super V recoil mitigation system.

Ideal for Home Defense and Personal Protection

The compact dimensions, light weight, and exceptional recoil control make the Vector SDP ideal for home defense applications. The ability to deliver rapid, accurate follow-up shots in confined spaces provides significant defensive advantages. The Glock magazine compatibility ensures access to reliable, high-capacity magazines for extended engagements.

The KRISS Vector SDP Gen 3 redefines pistol-format defensive firearms—revolutionary recoil control meets ultra-compact dimensions for unmatched controllability.
