Kriss USA KV903PWD00 Vector SDP Gen3 9mm Luger 40+1 5.50" Black Nitride Threaded Barrel, M-LOK Handguard, Picatinny Rail Receiver & Rear, Black Polymer Grip, Ambidextrous, Glock Mag Compatible

The Kriss USA Vector SDP Gen3 in 9mm Luger is a compact, modular platform built for shooters who want control, customization, and ergonomics in a personal protection or home defense carbine. This is the lightest iteration of the Vector family, redesigned from the ground up with a completely overhauled upper and lower housing architecture. If you've run Glock-pattern pistols or carbines, you'll feel at home immediately—the Vector SDP accepts standard full-size Glock magazines, giving you familiar manual-of-arms and ammunition compatibility across your lineup.

What sets the SDP Gen3 apart is its commitment to ambidextrous operation and configurable ergonomics. The magazine release, safety lever, and controls are all ambidextrous, meaning left- or right-handed shooters operate the gun without compromise. The new interchangeable pistol grip system (compatible with AR15/M16 grips) lets you dial in comfort and control to your hand. The M-LOK handguard and full-length Picatinny top rail provide straightforward rail real estate for optics, lights, and accessories, while the rear Picatinny rail accepts your choice of stabilizing brace or stock. The 5.5-inch barrel is threaded 1/2×28 RH, opening the door to suppressors or flash hiders, and finished in hard black nitride for corrosion resistance.

The action is a closed-bolt delayed blowback system—smooth, reliable, and softer shooting than straight blowback 9mm guns. Field stripping is tool-less via a 4-pin design, and the short charging handle with brass-check function keeps the gun running clean. You get a skeletonized trigger with minimal pre-travel, an ambidextrous short-throw safety, and a low-profile Gen3 upper that doesn't interfere with sight lines. Out of the box, you'll receive one 40-round magazine, a cleaning kit, cable lock, user manual, and warranty documentation.
