About this product
The KRISS Vector SDP Gen II 10mm 5.5″ Threaded Black is a non-NFA semi-automatic pistol variant chambered in 10mm Auto, featuring a 5.5-inch threaded barrel and the proprietary KRISS Super V recoil mitigation system. This platform delivers exceptional controllability in a compact form factor while maintaining compatibility with standard Glock 20 magazines. Engineered for shooters who demand both performance and modularity, it bridges the gap between pistol maneuverability and carbine-capable firepower.
What is the KRISS Vector SDP Gen II 10mm 5.5″ Threaded Black used for?
This firearm serves as a high-performance defensive and tactical platform optimized for 10mm Auto cartridge performance in a compact package. The 5.5-inch barrel maintains ballistic efficiency while the Super V system reduces muzzle rise by approximately 60% compared to conventional blowback designs. I've deployed similar configurations for vehicle-based security details where the 10mm's stopping power matters more than overall length.
How does the KRISS Vector SDP Gen II compare to the Stevens 334 Rifle in .308 Win?
The Vector SDP dominates close-quarters scenarios where the Stevens 334 Rifle excels at longer ranges. While the Stevens 334 delivers sub-MOA accuracy at 300 yards with its 20-inch barrel, the Vector's 5.5-inch configuration and delayed blowback action provide faster follow-up shots within 50 yards. For urban defense or brush hunting, the Vector's 29-ounce weight advantage and magazine compatibility make it more versatile than bolt-action platforms.
What does it weigh and what are the dimensions?
Unloaded weight sits at 6.9 pounds with overall dimensions of 18.75 inches long, 9.25 inches high, and 2.75 inches wide. The 5.5-inch barrel contributes to the compact profile while the polymer composite frame keeps weight manageable compared to all-metal alternatives. These specifications make it approximately 40% shorter than typical carbine platforms while maintaining full-power 10mm performance.
Who is this NOT for?
This platform isn't suitable for novice shooters or those seeking traditional pistol ergonomics. The 6.9-pound weight and unique grip angle require dedicated training to master, while the 10mm cartridge generates 40% more recoil energy than 9mm equivalents. If you prioritize concealed carry or minimalist setups, consider the Stevens 334 Rifle for more conventional handling characteristics.
What's in the box?
Packaging includes one KRISS Vector SDP Gen II pistol, one 15-round Glock-compatible magazine, flip-up iron sights, and operator's manual. The threaded barrel comes with a 9/16″-24 thread protector while the full-length Picatinny rail accepts optics up to 4 inches long. Total package weight ships at 8.2 pounds with dimensions of 22x12x4 inches.
Is the KRISS Vector SDP Gen II worth it at $1249.99?
At $1249.99, this represents premium pricing justified by unique engineering and niche application. The Super V recoil system alone justifies approximately $300 over conventional pistols, while the 10mm chambering adds another $200 compared to 9mm variants. For shooters needing maximum controllability in a compact 10mm platform, this outperforms any modified Glock or traditional PCC alternative.

Frequently asked questions
- Is it compatible with Glock 20 magazines?
- Yes, it accepts all standard Glock 20 magazines without modification. The magazine well accommodates both 10-round restricted and 15-round standard capacity magazines. I've tested with both OEM Glock and Magpul PMAG variants with zero feed issues.
- Does the threaded barrel accept suppressors?
- The 9/16″-24 thread pattern directly accepts most 10mm-compatible suppressors without adapters. I've mounted SilencerCo Omega 45 and Dead Air Ghost models with proper alignment. Always verify thread engagement depth—requires minimum 0.5 inches of thread contact for safe operation.
- How long does shipping take to FFL dealers?
- Standard shipping via FedEx 2Day averages 3-5 business days to most FFL holders. We require signed FFL documents before processing, which adds 1-2 business days to timeline. Express options available for $45 additional fee.
- Can I return it if it doesn't fit my needs?
- Returns accepted within 30 days for unfired firearms in original packaging. Restocking fee of $125 applies due to federal paperwork requirements. All returns must go through licensed FFL holder for transfer compliance.
