The Kriss USA Vector SDP Gen3 in 45 ACP is a compact, modern submachine gun platform built for home defense, personal protection, and tactical training. If you've shot a Glock or trained with Glock-pattern magazines, you'll appreciate the Vector SDP's compatibility right out of the box—it feeds standard full-size Glock magazines and ships with one 30-round magazine. At 5.6 pounds and 15.35 inches collapsed, it balances control and maneuverability without sacrificing practical firepower.
The Gen3 SDP represents a complete redesign of the Vector chassis. The upper and lower housings have been reworked for modularity and ergonomics, giving you a wider, more supportive platform for both hands. The M-LOK handguard integrates seamlessly with a full-length Picatinny rail on top and a rear Picatinny rail for stocks or devices, letting you configure the gun to your needs. Ambidextrous controls—mag release, bolt release, and short-throw safety lever—make the Vector equally at home for left and right-handed shooters. The interchangeable grip system accepts both Kriss-spec grips and standard AR15/M16 pistol grips, so you can dial in your preferred ergonomics.
Reliability comes from a closed-bolt, delayed-blowback operating system and a 4140 chrome-moly barrel finished in QPQ black nitride (.578x28 RH threaded). The skeletonized trigger breaks at a single stage with minimal pre-travel, and the short charging handle includes a brass deflector for ambidextrous use. Field stripping is tool-free via four pins—a practical feature when you're cleaning after a long range session or training day.
Included in the box: the firearm, one 30-round magazine, cleaning kit, cable lock, user manual, and warranty card. Whether you're setting up for home defense, recreational shooting, or exploring the Vector platform, the SDP Gen3 delivers the accuracy, modularity, and magazine compatibility to get you running quickly.
