Kriss Vector Sdp G3 10Mm 5.5 Blk 33Rd

The Kriss Vector SDP G3 10mm is a compact, semi-automatic pistol built for shooters who want serious stopping power in a manageable package. The SDP (Smallest Displacement Pistol) form factor keeps overall length to 15.35 inches when collapsed, making it suitable for home defense, personal protection, and shooters seeking a potent 10mm platform without a full-size rifle footprint. The delayed blowback operating system manages recoil and keeps the gun running reliably across the spectrum of 10mm loads.

Out of the box, the Vector SDP G3 feeds standard Glock-pattern magazines—the included 33-round magazine means you get serious capacity without hunting for aftermarket solutions. That familiarity extends to the controls: an ambidextrous magazine release, short-throw safety lever on both sides, and an interchangeable AR15/M16 pistol grip let you configure the gun to your hand and preference. The skeletonized trigger has minimal pre-travel, and a short charging handle with brass-check function keeps charging ergonomic and positive.

The Gen 3 redesign brought a low-profile upper housing and overhauled mounting block, giving you real customization room. A full-length Picatinny rail on top and a rear rail under the stock mount point mean you can dress this gun for whatever mission you have in mind. The 5.5-inch 4140 chrome-moly barrel is finished in black nitride and threaded 9/16x24 for suppressors. All of that comes together in a 5.6-pound platform that feels purpose-built rather than compromised.

If you're in the 10mm camp and want a modern, configurable, hammer-down platform for defense or range work, the Vector SDP G3 delivers ballistics and ergonomics that punch well above its compact footprint.
