The Kriss Vector SDP Gen 3 9mm is a compact, purpose-built semi-automatic carbine designed for shooters who want rifle ergonomics and control in a smaller, lighter package. Built on the proven delayed blowback operating system that made the Vector family famous, the SDP (Super Duty Pistol) cuts down the form factor without compromising on handling. At 5.6 pounds and 15.35 inches collapsed, it's nimble enough for home defense, vehicle carry, or close-quarters scenarios where a full-size rifle won't fit—yet the 5.5-inch barrel and full-length Picatinny rail give you the controls and customization you'd expect from a modern tactical platform.
The Gen 3 redesign brings real improvements: completely reworked upper and lower housings that enhance hand support and open the gun up for modular customization. Magazine interchangeability with Glock-pattern mags means if you already shoot Glock pistols, your ammunition supply and magazine investments work here too. Ambidextrous controls—mag release, safety lever, and charging handle—make it equally at home for lefties and righties. The short throw safety and low-profile upper receiver keep the profile clean, while the skeletonized trigger with minimal pre-travel gives you a clean press without excess creep.
Built on a 4140 chrome moly barrel with black nitride finish and threaded 1/2x28 for suppressors, the Vector SDP is made to run. Field stripping is fast—four pins, no tools. The included 40-round magazine and full suite of ambidextrous features make this a serious option if you want rifle-class reliability and ergonomics in a space-efficient, customizable platform.

Yes. The Vector SDP is fed with full-size Glock-pattern magazines, so if you already own Glock pistols or have Glock mags on hand, they'll work seamlessly in this platform. The gun ships with one 40-round magazine.
The SDP's compact form factor—15.35 inches collapsed—and semi-automatic closed bolt design make it well-suited for home defense. The delayed blowback system, short barrel, and full complement of rails for optics and lights support defensive setups. However, choice of platform for home defense depends on your training, local law, and comfort with the platform.
Yes. The 5.5-inch barrel is threaded 1/2x28 RH, so you can attach suppressors, flash hiders, or other muzzle devices with the appropriate adapters.
The Vector SDP features an ambidextrous magazine release, ambidextrous short throw safety lever, and ambidextrous bolt release. It also accepts interchangeable AR-15/M16 pistol grips, so you can configure it for either hand.
