The Kriss USA Vector SDP G3 9mm is a modern, direct-blowback submachine gun platform designed for shooters who want controllability, modularity, and a truly flat shooting experience. This 5.5-inch barreled variant in Flat Dark Earth delivers the legendary Vector ergonomics in a compact, maneuverable package—ideal for home defense, range work, or tactical training where you need serious handling characteristics in a semi-automatic platform. If you've shot a Vector and loved the hydraulic recoil mitigation, the SDP G3 brings that same mechanical advantage to a shorter, lighter frame.
The Vector SDP G3 uses a closed-bolt, delayed-blowback operating system that's engineered to keep the shooter behind the gun—no violent recoil impulse, no muzzle rise, just straight-back push. The trigger is a single-stage pivoting design that breaks cleanly, and the whole gun feels refined and purpose-built rather than cobbled together. At 5.6 pounds unloaded, it's nimble enough for rapid transitions and precise shot placement, whether you're running drills at the indoor range or evaluating it for duty applications.
Build quality is serious: 4140 chrome-moly barrel with black nitride (QPQ) finish means corrosion resistance and longevity. The barrel is threaded 1/2 x 28 RH, so you can run a suppressor or muzzle device if your jurisdiction allows. You get one 40-round magazine included, so you can shoot immediately out of the box—that's a magazine capacity most shooters never expected from a pistol-caliber platform.

Yes—the barrel is threaded 1/2 x 28 RH, so you can mount a suppressor or other muzzle device. Check your local laws on suppressor ownership and use before purchasing.
You get the Kriss USA Vector SDP G3 and one 40-round magazine, so you're ready to shoot straight away.
No, this is the SDP G3 semi-automatic version. It fires one round per trigger press.
The closed-bolt, delayed-blowback operating system is engineered to reduce felt recoil and muzzle rise compared to traditional direct-blowback designs. This helps you stay on target for faster, more accurate follow-ups.
