The Kriss USA Vector SDP G3 10mm is a unique, modern pistol-caliber carbine built on the proven Vector platform—designed for shooters who want soft-shooting 10mm performance with serious stopping power and practical handling. The SDP (Short Delayed Blowback Platform) runs a closed-bolt, delayed-blowback operating system that tames the 10mm's recoil impulse far better than a traditional blowback design, making rapid, accurate follow-up shots achievable even for newer shooters. With a 5.5-inch barrel and flat dark earth finish, it's equally at home as a home-defense tool, truck gun, or range performer.
The Vector SDP G3 comes with a generous 33-round magazine, extending your capacity and reducing reload frequency during range sessions or training. The barrel is constructed from 4140 chrome-moly steel with a durable black nitride finish (QPQ process) that resists corrosion and handles hard use. The threaded 9/16x24 RH barrel accepts common 10mm suppressors and muzzle devices, opening up quiet shooting or compensated shooting options. A single-stage pivoting trigger keeps the action clean and responsive.
At 5.6 pounds and 15.35 inches overall length when fully collapsed, the Vector SDP G3 is compact enough to stow or carry but long enough to deliver solid sight radius and practical handling. If you shoot 10mm and want a carbine that actually mitigates recoil rather than amplifying it, or if you're looking for a 10mm platform that feels different and shoots flatter than the field, the Vector SDP G3 delivers a genuinely modern take on pistol-caliber rifle design.

Yes. The barrel is threaded 9/16x24 RH, which is a standard 10mm suppressor thread pitch. You can add a suppressor, compensator, or other muzzle device to suit your shooting needs.
The Vector SDP G3 uses a closed-bolt delayed-blowback operating system that significantly reduces felt recoil compared to traditional blowback designs. This translates to faster, more accurate follow-up shots and less wear on components, especially important in a full-power 10mm round.
The Vector SDP G3 ships with one 33-round magazine, giving you substantial capacity for range time, training, or defensive use.
At 15.35 inches overall length when collapsed and 5.6 pounds, the Vector SDP G3 is compact enough for vehicle storage, home defense, or as a truck gun. The 10mm round and 33-round magazine provide serious stopping power and capacity, making it a capable choice for defensive scenarios.
