About this product
What is the KRISS USA Vector SDP G2 9mm 5.5″ ODG? It's a 9mm pistol caliber carbine platform that leverages a patented delayed-blowback system to achieve 40+1 capacity with dramatically reduced muzzle climb compared to direct blowback designs. Chambered in 9mm with a 5.5-inch threaded barrel, this platform bridges the gap between handgun portability and rifle-caliber controllability while maintaining NFA pistol classification.
What is the KRISS USA Vector SDP G2 used for?
The Vector SDP G2 serves as a high-capacity range weapon and suppressor host that maintains controllability under rapid fire. With its 40-round magazine capacity and Super V recoil mitigation system, it allows shooters to maintain target acquisition through multiple rounds where conventional PCCs would lose zero. The threaded 5.5-inch barrel accepts common 1/2×28 muzzle devices, making it ideal for both training scenarios and practical shooting applications where rapid follow-up shots matter.
How does the KRISS Vector compare to the CZ Scorpion EVO 3 S1?
The KRISS Vector's recoil mitigation system provides approximately 40% less perceived recoil impulse than the direct blowback CZ Scorpion EVO 3 S1 during sustained fire. While both platforms offer similar 9mm chambering and threaded barrels, the Vector's closed-bolt, delayed-blowback operation reduces muzzle climb significantly, though it comes at a 1.2-pound weight penalty (7.4 lbs vs 6.2 lbs unloaded) and higher price point. The Scorpion offers better aftermarket support, but the Vector delivers superior mechanical recoil control.
What does it weigh and what are the dimensions?
The Vector SDP G2 weighs 7.4 pounds unloaded and measures 16.5 inches in overall length with a 5.5-inch barrel. With its folded stock deployed, the length extends to 25.8 inches, making it roughly 3 inches shorter than the Stevens 334 Rifle in .308 Win when both are configured for shoulder firing. The 40-round polymer magazine adds 0.8 pounds when fully loaded, bringing total weight to 8.2 pounds for a full combat load.
Who is this NOT for?
This platform isn't suitable for concealed carry or users seeking lightweight PDW applications where every ounce counts. At 7.4 pounds unloaded, it weighs nearly double many polymer-frame handguns and requires specific holster solutions that accommodate its unconventional profile. Shooters on tight budgets should consider more traditional PCC platforms like the Stevens 555 Sporting shotgun for entry-level training, as the Vector's specialized mechanics command a premium price.
What's in the box?
The package includes one 40-round Glock-pattern magazine, operator's manual, and cable lock—no optics or additional accessories. Unlike some competitors that bundle multiple magazines or sighting systems, KRISS keeps the configuration lean to maintain the $1307.99 price point, requiring buyers to budget separately for optics mounts and additional magazines. The manual includes detailed disassembly instructions specific to the Gen 2's improved takedown mechanism.
Is the KRISS Vector worth it at $1307.99?
At $1307.99, the Vector justifies its price through engineering that genuinely changes the shooting experience rather than cosmetic upgrades. The recoil mitigation system isn't marketing fluff—it measurably reduces muzzle climb by redirecting recoil forces downward, allowing faster target reacquisition that competing PCC designs can't match mechanically. For shooters who value mechanical innovation over aftermarket customization, the Vector delivers tangible performance differences that cheaper blowback designs simply cannot replicate.

Frequently asked questions
- Is it compatible with Glock magazines?
- Yes, the Vector SDP G2 uses standard Glock-pattern magazines, including the included 40-round extended magazine and common 17-round or 33-round options. This compatibility provides access to widespread aftermarket support and affordable replacement magazines from numerous manufacturers like Magpul and ETS.
- Does it fit in a standard pistol case?
- No, the Vector requires a case at least 17 inches long internally to accommodate its 16.5-inch folded length. Most standard handgun cases max out at 14 inches, so you'll need a compact rifle case or specialized PCC bag. I recommend cases from Savior Equipment or Voodoo Tactical for proper fitment.
- How long does shipping take?
- Firearms shipping typically takes 3-7 business days to your selected FFL dealer after order processing and background check completion. All shipments require signature confirmation and transfer through a licensed dealer, adding approximately 2-3 days for paperwork processing versus standard retail shipping times.
- Can I return it if it doesn't fit my needs?
- Firearms sales are generally final once transferred through an FFL due to federal regulations, though Ironclad Armory offers a 30-day warranty on manufacturing defects. We recommend handling the firearm at your local dealer before purchase to ensure the 7.4-pound weight and unusual balance point meet your expectations.
