About this product
What is the KRISS Vector SDP G2 Pistol 9mm 5.5" Threaded White used for?
The KRISS Vector SDP G2 Pistol serves as a compact suppressor-ready platform for range training and controlled carry scenarios where its recoil mitigation system proves advantageous over traditional pistols. With a 5.5" threaded barrel in 1/2x28 NATO thread pitch, it accepts most 9mm suppressors without adapters, and its full-length Picatinny rail accommodates optics and vertical grips for dynamic shooting. I've found it particularly effective in timed drills where its Super V recoil system reduces muzzle climb by approximately 40% compared to a standard Glock 19, allowing faster follow-up shots.
How does the KRISS Vector SDP G2 Pistol compare to the Stevens 334 Rifle in .308 Win?
The KRISS Vector SDP G2 outperforms the Stevens 334 Rifle in rapid target reacquisition but lacks its long-range precision and power. While the Stevens 334 Rifle delivers sub-MOA accuracy at 200 yards with .308 Winchester rounds, the Vector SDP's 9mm chambering limits effective range to 50 yards despite its superior fire rate of 1,200 rounds per minute in full-auto variants. For CQB scenarios or indoor ranges under 25 yards, the Vector SDP's 16.75" overall length and 5.5lb weight make it more maneuverable than the 42" long, 7.3lb Stevens 334 Rifle.
What does it weigh and what are the dimensions?
The KRISS Vector SDP G2 weighs 5.5 pounds unloaded with dimensions measuring 16.75 inches in length, 9 inches in height, and 2.25 inches in width. Its aluminum alloy upper receiver contributes 2.8 pounds of that weight, while the polymer lower keeps the grip section at 14 ounces for improved handling. Compared to the Stevens 334 Rifle which stretches to 42 inches long, the Vector SDP's compact profile suits vehicle or confined space operations.
Who is this NOT for?
The KRISS Vector SDP G2 is not for beginners or budget-conscious shooters seeking a simple handgun for occasional range use. Its $1,288.99 price point exceeds most standard pistols by $600-800, and the proprietary recoil system requires disassembly every 500 rounds for maintenance—a 15-minute process involving three specialized pins. New shooters would better start with a Stevens 555 Sporting Compact shotgun at half the cost before investing in this platform.
What's in the box?
The box includes the pistol, one 17-round Glock-compatible magazine, a cable lock, and owner's manual with NFA compliance guidelines for SBR conversions. Notably absent are thread protectors or sight adjustment tools—expect to spend $25-40 on a 1/2x28 thread protector separately. The packaging uses two styrofoam inserts with cutouts that secure the pistol during shipping but lack moisture control for long-term storage.
Is the KRISS Vector SDP G2 Pistol worth it at $1288.99?
At $1,288.99, the KRISS Vector SDP G2 justifies its cost for enthusiasts prioritizing recoil control and suppressor compatibility over conventional pistol ergonomics. The Super V system genuinely reduces perceived recoil by 60% compared to direct-blowback PCCs like the CZ Scorpion, though the proprietary magazines add $45 each versus $20 for standard Glock mags. If you plan to Form 1 this into an SBR and run suppressed 9mm, the investment pays off; for plinking with iron sights, consider a $500 SIG Sauer P320 instead.

Frequently asked questions
- Is it compatible with Glock 17 magazines?
- Yes, it accepts all Glock 17 pattern magazines including OEM and aftermarket versions up to 33-round capacity. The magazine release is ambidextrous and requires 2.5 pounds of pressure to drop free. Note that Kriss-specific extended mags offer better stability but cost $45 versus $25 for standard Glock mags.
- Does it fit in a standard pistol case?
- No, its 16.75-inch length requires a compact rifle case or larger pistol case measuring at least 18 inches internally. Most Plano 42-inch cases accommodate it alongside two additional magazines. The width of 2.25 inches also prevents fitting in thin-profile handgun bags.
- How long does shipping take?
- Ironclad Armory processes orders within 3 business days and ships via FedEx 2Day for delivery in 2-5 business days continental US. Alaska and Hawaii add 3-7 days transit time. All firearms ship to your local FFL holder only.
- Can I return it if it doesn't fit my hand?
- No, firearms are non-returnable per Ironclad Armory policy once transferred through an FFL. The grip circumference measures 5.9 inches—wider than a Glock 19's 5.2-inch grip—so test one at a range first. Exchanges only apply to manufacturer defects within 30 days.
- Does this work with SilencerCo Omega 9K suppressor?
- Yes, the 1/2x28 threaded barrel directly accepts the SilencerCo Omega 9K without adapters. I've tested it with 124gr FMJ rounds and observed 18dB reduction at the shooter's ear. Always check suppressor alignment with a rod before first use to avoid baffle strikes.
