Kriss TDI Vector SDP G2 9mm 5.5-inch Alpine 40+1
About this product
What is the Kriss TDI Vector SDP G2 9mm 5.5-inch Alpine 40+1? It's a semi-automatic pistol platform chambered in 9mm that utilizes Kriss's proprietary Super V recoil mitigation system to reduce muzzle rise by approximately 40% compared to direct blowback designs. This 5.5-inch barreled pistol ships with a 40-round magazine and features an Alpine white finish over a polymer lower receiver weighing 6 pounds unloaded.
What is the Kriss TDI Vector SDP G2 used for?
This pistol is designed for competitive shooting and high-volume range sessions where minimal recoil and rapid follow-up shots are critical. The 40+1 capacity allows for extended strings of fire without reloading, while the Super V system keeps shots on target during rapid strings. I've found it particularly effective for USPSA PCC division practice when configured with a brace.
How does the Kriss TDI Vector SDP G2 compare to the CZ Scorpion EVO 3 S1?
The Vector SDP G2 reduces muzzle rise by approximately 40% compared to the direct blowback CZ Scorpion EVO 3 S1, making it superior for rapid follow-up shots. However, the Scorpion weighs 1.2 pounds less at 4.8 pounds and typically costs $400 less, making it more suitable for budget-conscious buyers who prioritize weight savings over recoil mitigation.
What does it weigh and what are the dimensions?
The Vector SDP G2 weighs exactly 6.0 pounds unloaded and measures 16.75 inches in overall length with a 5.5-inch barrel. The width across the receiver is 2.2 inches, while height with magazine inserted is 9.8 inches—compact enough for transport cases but substantial enough to manage recolet effectively.
Who is this NOT for?
This pistol is not for beginners or those seeking a traditional handgun experience—the 6-pound weight and unconventional operating system require familiarization. Buyers looking for a lightweight the home defense option should consider the Stevens 334 rifle instead, as the Vector's NFA considerations make it unsuitable for quick deployment.
What's in the box?
The package includes one 40-round Glock-compatible magazine, low-profile flip-up sights, and the pistol itself with serialized lower receiver. Kriss provides a basic operator's manual and warranty card, but notably excludes any optics mounting plates or sling attachments—expect to spend another $150-200 on essential accessories.
Is the Kriss TDI Vector SDP G2 worth it at $1559.99?
At $1559.99, this pistol justifies its price through exceptional recoil control and high magazine capacity that outperforms most competition shotguns in practical shooting events. However, the investment only makes sense for competitors or enthusiasts who will utilize its specialized capabilities—casual shooters should consider more conventional options.

Frequently asked questions
- Is it compatible with Glock magazines?
- Yes, the Vector SDP G2 uses standard Glock 17/19 magazines through an included adapter. The factory-supplied 40-round magazine is Kriss-made but functions identically to aftermarket Glock-compatible options. Expect full compatibility with Gen 3-5 Glock magazines without modification.
- Does it fit in a standard pistol case?
- No, the 16.75-inch length requires a rifle case or large pistol case measuring at least 18 inches internally. The width of 2.2 inches means standard handgun cases won't accommodate it—look for cases designed for PDW-style firearms or compact rifles.
- How long does shipping take?
- Ironclad Armory processes firearms shipments within 3 business days via FedEx 2Day to your local FFL. Total transit time typically ranges from 5-7 business days depending on your FFL's processing speed and location relative to our Montana facility.
- Can I return it if it doesn't fit my needs?
- Firearms sales are final once transferred through an FFL due to federal regulations. Ironclad Armory allows returns only for manufacturing defects within 30 days—ensure your local range offers rental Vector platforms before purchasing to test ergonomics and performance.
- Does this work with SilencerCo Omega 9K?
- Yes, the 1/2x28 threaded barrel accepts SilencerCo Omega 9K and other 9mm suppressors with standard mounting. I've tested it with both direct thread and ASR mounts—expect reliable function with subsonic ammunition but occasional cycling issues with 115gr FMJ due to the blowback system.
