About this product
The KRISS Vector SDP G2 5.5″ MC FDE is a semi-automatic pistol chambered in 9mm that leverages KRISS's patented Super V recoil mitigation system to deliver exceptional controllability in a compact package. This MultiCam Flat Dark Earth finished platform ships with a 40-round Glock-compatible magazine and features a 5.5-inch threaded barrel for suppressor or muzzle device compatibility. As someone who's spent over a decade evaluating Title II firearms, I appreciate how this design bridges the gap between pistol maneuverability and carbine-level performance.
What is the KRISS Vector SDP G2 used for?
The Vector SDP G2 excels as a high-capacity defensive or competition pistol where rapid follow-up shots matter. Its 6-pound weight and 16.75-inch overall length make it ideal for vehicle deployment or close-quarters scenarios requiring magazine compatibility with common Glock platforms. The Super V system redirects recoil downward rather than backward, reducing muzzle climb by approximately 60% compared to direct blowback systems.
How does the KRISS Vector SDP G2 compare to the CZ Scorpion EVO 3 S1?
The Vector SDP G2 offers superior recoil mitigation but requires more maintenance than the simpler CZ Scorpion EVO 3 S1. While the Scorpion uses a straightforward blowback system that's easier to clean, the Vector's complex Super V mechanism demands detailed disassembly every 500 rounds to maintain optimal performance. For shooters prioritizing flat shooting over simplicity, the Vector's mechanical advantage is worth the extra upkeep.
What does it weigh and what are the dimensions?
This pistol weighs exactly 6.0 pounds unloaded and measures 16.75 inches in overall length with its 5.5-inch barrel. The height from rail to grip base is 8.25 inches, and the width across the receiver is 1.75 inches—compact enough for tactical bags but substantial enough to manage the .40-caliber version's recoil impulse if you choose to caliber-convert later.
Who is this NOT for?
This isn't for beginners or budget-conscious shooters who'd be better served by a Stevens 334 rifle for half the price. The Vector's $1,559.99 MSRP and complex maintenance requirements make it a poor choice for someone wanting a simple plinking firearm. If you're not comfortable detail-stripping a firearm with 37 discrete components in the recoil system alone, consider a more conventional platform.
What's in the box?
You receive one complete pistol, one 40-round Glock-compatible magazine, and basic documentation—but notably no cleaning tools specific to the Super V system. The package includes flip-up sights that require a 2.5mm hex key for windage adjustment, which isn't included. Compared to the Stevens 555 Sporting shotgun that includes choke tubes and a hard case, the Vector's packaging is minimalistic.
Is the KRISS Vector SDP G2 worth it at $1,559.99?
At $1,559.99, this represents fair value for shooters who'll leverage its unique recoil reduction in competitive or defensive roles. The MultiCam Cerakote finish adds about $150 value over standard finishes, and the included 40-round magazine is a $45 component. For those needing maximum controllability in a compact package, the engineering justifies the premium over conventional pistols.

Frequently asked questions
- Is it compatible with Glock magazines?
- Yes, it accepts standard Glock 17/19/26 magazines and aftermarket equivalents. The magazine well accommodates double-stack 9mm Glock pattern magazines from 10 to 40 rounds. I've tested it with OEM Glock, Magpul PMAGs, and ETS clear magazines—all function reliably.
- Does the threaded barrel accept suppressors?
- The 1/2x28 threaded muzzle accommodates most 9mm suppressors without adapters. Threads are cleanly cut and concentric—I've mounted SilencerCo Omega 9K and Dead Air Wolfman suppressors without alignment issues. Always use a crush washer or suppressor alignment rod before permanent attachment.
- How long does shipping take to FFL dealers?
- Ironclad Armory processes orders within 2 business days, with ground shipping taking 3-7 days depending on your FFL's location. All shipments require signature confirmation at the receiving FFL. We recommend contacting your dealer before ordering to confirm they accept transfers from online retailers.
- Can I shoulder the pistol brace version?
- Current ATF rulings classify shouldering a pistol brace as redesigning the firearm into an SBR, requiring a Form 1 tax stamp. The SDP model ships as a pistol—consult legal counsel before modifying its configuration. I maintain NFA compliance by using mine with a single-point sling for stability.
