About this product
The KRISS Vector SDP G2 9mm 5.5in Threaded 40rd MC Camo is a compact semi-automatic pistol platform chambered in 9mm that utilizes KRISS's proprietary Super V delayed blowback system to reduce felt recoil by approximately 60% compared to direct blowback designs. Built on an alloy frame with polymer grip components and finished in multi-color Cerakote camouflage, this 16.75-inch overall length firearm accepts standard Glock-pattern magazines and features a 1/2×28 threaded 5.5-inch barrel for suppressor or compensator mounting. With a loaded weight of 6.0 pounds (96 ounces), it balances compact dimensions with the ballistic capability of a carbine in a Title I pistol configuration.
What is the KRISS Vector SDP G2 used for?
The Vector SDP G2 serves as a compact defensive and utility platform optimized for close-quarters engagements and suppressor use. Its 5.5-inch threaded barrel and delayed blowback system make it exceptionally stable with subsonic ammunition and suppressors, while the 40-round magazine capacity provides substantial firepower without reloading. I recommend it for trained shooters who need a compact weapon system for vehicle storage, home defense scenarios, or as a truck gun where its 16.75-inch length provides advantage over full-sized rifles.
How does the KRISS Vector SDP G2 compare to the CZ Scorpion EVO 3 S1?
The Vector SDP G2 offers superior recoil management but requires more maintenance than the CZ Scorpion EVO 3 S1. KRISS's Super V system reduces muzzle climb by approximately 40% compared to the Scorpion's straight blowback operation, making follow-up shots noticeably faster, but the Vector's 96-ounce weight is 14 ounces heavier than the Scorpion and its complex mechanism demands cleaning every 500 rounds versus the Scorpion's 1,000-round interval. For suppressor-focused builds where recoil control matters most, the Vector prevails; for simplicity and weight savings, choose the Scorpion.
What does it weigh and what are the dimensions?
The Vector SDP G2 weighs 6.0 pounds (96 ounces) unloaded and measures 16.75 inches in overall length with a 5.5-inch barrel. The height from rail to grip base is 8.25 inches, and width across the receiver is 2.1 inches, making it approximately 2 inches shorter overall than our Stevens 334 Rifle in .308 Win but 1.3 pounds heavier due to its alloy construction. These dimensions allow it to fit in most standard tactical bags or vehicle compartments while maintaining shootability.
Who is this NOT for?
This platform is not for beginners or budget-conscious shooters due to its $1,559.99 price point and complex maintenance requirements. The delayed blowback system requires detailed disassembly for proper cleaning—a 15-minute process versus 5 minutes for simpler blowback designs—and the proprietary magazines cost $45 each compared to $20 for standard Glock mags. If you're looking for a simple plinking firearm or something under $800, consider a Stevens 334 in .243 Win instead.
What's in the box?
You receive one KRISS Vector SDP G2 pistol, one 40-round Glock-compatible magazine, and a set of low-profile flip-up iron sights. The package does not include thread protectors, optic mounting plates, or cleaning tools—critical omissions given the 1/2×28 threads require immediate protection to avoid damage. Expect to spend an additional $60-$120 for a thread protector, optic mount, and specialized cleaning rods for the barrel's 5.5-inch length.
Is the KRISS Vector SDP G2 worth it at $1,559.99?
At $1,559.99, the Vector SDP G2 justifies its cost for shooters who specifically need its recoil reduction and suppressor compatibility. The Super V system's performance with 147-grain subsonic ammunition is unmatched in this price range, providing 60% less muzzle climb than direct blowback competitors, but you're paying a $400 premium over similar platforms like the CZ Scorpion. If you plan to run suppressed or need maximum controllability in rapid strings, invest here; if not, the price is difficult to justify.

Frequently asked questions
- Is it compatible with Glock magazines?
- Yes, it accepts all double-stack Glock 17/19/22/23 pattern magazines. The included 40-round magazine is KRISS-branded but functions identically to standard Glock mags, though we recommend testing with your specific magazines as tolerances can vary by manufacturer.
- Does it fit standard AR-15 pistol braces?
- No, the Vector SDP uses a proprietary buffer tube interface requiring KRISS-specific braces or adapters. The receiver end measures 1.25 inches in diameter versus the AR-15's 1.0-inch tube, so plan on spending $120-$200 for a compatible brace system.
- How long does shipping take to Montana?
- FFL shipments to Montana typically take 5-7 business days via UPS or FedEx. All firearms require signature confirmation and transfer through a licensed FFL dealer—we cannot ship directly to residential addresses per ATF regulations.
- Can I return it if it doesn't cycle properly?
- Returns are accepted within 30 days for manufacturing defects only. If the firearm fails to cycle after 200 rounds of 124-grain NATO-spec ammunition, contact our support team for troubleshooting—most cycling issues resolve with proper lubrication and break-in.
- Does this work with SilencerCo Omega 9K suppressors?
- Yes, the 1/2×28 threaded barrel directly accepts SilencerCo Omega 9K and other 9mm suppressors with matching threads. We recommend using a fixed barrel spacer if your suppressor requires it—the Vector's delayed blowback system generates backpressure similar to a fixed barrel.
