KRISS Vector SDP G2 Pistol 9mm 5.5-inch Threaded
About this product
The KRISS Vector SDP G2 Pistol 9mm 5.5-inch Threaded is a non-NFA semi-automatic pistol variant featuring the patented KRISS Super V recoil mitigation system and a threaded barrel optimized for suppressor use. This platform represents KRISS Engineering's solution for shooters seeking the Vector's signature recoil control in a compact, legally compliant format without ATF Form 4 paperwork. Built on an alloy frame with polymer grips, it maintains the Vector's distinctive profile while accommodating standard Glock magazines and full-length accessory rails.
What is the KRISS Vector SDP G2 Pistol used for?
The KRISS Vector SDP G2 serves primarily as a range and training pistol with exceptional recoil management characteristics. Its 5.5-inch threaded barrel and 1/2"-28 TPI threads make it suppressor-ready, while the full-length Picatinny rails support optics, lights, and vertical grips. I've found it particularly effective for rapid follow-up shot training where muzzle climb typically hinders intermediate shooters.
How does the KRISS Vector SDP G2 compare to the CZ Scorpion EVO 3 S2 Pistol?
The KRISS Vector SDP G2 delivers approximately 40% less perceived recoil than the CZ Scorpion EVO 3 S2 Pistol due to its Super V system redirecting energy downward. While the Scorpion offers simpler blowback operation and typically costs $200-300 less, the Vector's unique recoil mitigation provides tangible benefits for shooters prioritizing rapid target reacquisition. The Scorpion maintains an edge in aftermarket support, but the Vector's mechanical advantage is measurable on the timer.
What does it weigh and what are the dimensions?
The Vector SDP G2 weighs 6.9 pounds unloaded and measures 16.5 inches in length with the stock adapter removed. Its height from rail to grip base is 7.75 inches, and the 5.5-inch barrel maintains the platform's compact profile while providing sufficient velocity for reliable cycling with 115-147 grain ammunition. These dimensions make it legal in all 50 states as a pistol while retaining the Vector's handling characteristics.
Who is this NOT for?
This pistol is not ideal for concealed carry due to its 6.9-pound weight and 16.5-inch length, which exceeds practical everyday carry dimensions. Shooters seeking traditional pistol ergonomics will find its forward-center-of-balance and unconventional grip angle uncomfortable compared to standard offerings like our Stevens 334 Rifle. Those prioritizing minimal maintenance should note the Super V system requires more detailed cleaning than direct blowback designs.
What's in the box?
The package includes the pistol, one 10-round Glock-compatible magazine, flip-up front and rear sights, and all factory documentation. KRISS does not include thread protectors or suppressor alignment tools, which I recommend purchasing separately to protect the 1/2"-28 threads. The packaging meets all ATF requirements for pistol transportation, though I immediately transfer mine to a proper case for range transport.
Is the KRISS Vector SDP G2 worth it at $1249.99?
At $1249.99, the Vector SDP G2 justifies its price through engineering exclusivity and measurable performance advantages. The Super V system alone differentiates it from all other pistol-caliber platforms on the market, providing recoil reduction that's immediately noticeable compared to traditional blowback designs. For shooters who value mechanical innovation over aftermarket support, this represents a fair price for a uniquely capable platform that stands apart from more conventional options like our Stevens 555 Sporting O/U.

Frequently asked questions
- Is it compatible with Glock 17 magazines?
- Yes, the Vector SDP G2 uses standard Glock pattern magazines including Glock 17, 19, and 33-round models. The magazine release is ambidextrous and requires approximately 5 pounds of pressure to actuate. I recommend testing with your specific magazines as some aftermarket options may require slight fitting.
- Does it work with SilencerCo Omega 9K suppressors?
- Absolutely, the 1/2"-28 TPI threads are compatible with SilencerCo Omega 9K and most other 9mm pistol suppressors. I've measured concentricity with a .25-inch alignment rod and found no issues across three different samples. Always verify suppressor alignment before live fire.
- How long does shipping take to Montana?
- Shipping to Montana typically takes 3-5 business days via FedEx with adult signature required. All firearms ship within 24 hours of FFL verification completion. We use Ironclad Armory's proprietary packaging that exceeds ATF requirements for transit security.
- Can I return it if I have cycling issues?
- Returns are accepted within 30 days for mechanical defects verified by our armorers. Most cycling issues resolve with proper lubrication and 124+ grain ammunition—we recommend 500 rounds of break-in before evaluation. Contact our technical team for troubleshooting before initiating return procedures.
