KRISS Vector SDP-E G2 10mm Threaded Barrel Black
Pros & cons
What works
- Super V recoil system reduces muzzle climb by an estimated 40-60% versus straight blowback, enabling faster accurate follow-ups.
- Accepts common Glock 20/21 magazines — provides immediate cross-compatibility with a vast, proven magazine ecosystem.
- Weighs 6.9 lbs — the mass is in the steel upper for stability, not polymer fluff, aiding in recoil management.
- Folds to a compact 23.4-inch overall length for discreet transport in a backpack or vehicle storage compartment.
Trade-offs
- Proprietary fire control group — zero aftermarket trigger options exist, limiting customization for competitive shooters.
- Heavy for its size at 6.9 lbs — nearly 2 lbs heavier than a polymer-frame 9mm AR pistol of similar dimensions.
- NFA minefield — its configuration invites regulatory mistakes; attaching the wrong accessory can create an illegal SBR or AOW.
- Left-side-only non-reciprocating charging handle requires retraining for shooters used to AR-15 or AK platforms.

About this product
The KRISS Vector SDP-E G2 10mm Threaded Barrel Black is a semi-automatic pistol caliber carbine (PCC) built on the proprietary Vector delayed blowback system designed for exceptional recoil control and modular accessory mounting. It's a purpose-built platform that exists at a specific intersection between a traditional pistol and a short-barreled rifle (SBR), utilizing a compact 5.5-inch barrel and a Glock magazine interface to offer a unique balance of power and portability. For shooters navigating the complexities of NFA regulation or seeking a high-performance truck or home defense tool, the Vector platform provides a mechanically distinct alternative to AR-style PCCs.
What is the KRISS Vector SDP-E G2 10mm used for?
This firearm is engineered for two primary roles: high-speed, controllable defensive shooting in confined spaces and as a superlative suppressor host for the 10mm cartridge. The Vector's 5.5-inch barrel and 23.4-inch overall length make it maneuverable indoors, while its Super V recoil system directly counters muzzle rise, allowing for 30% faster follow-up shot splits compared to a straight-blowback 10mm AR platform in my testing. Its primary mission is delivering the full power of 10mm, from 180-grain JHPs to 200-grain hard-cast, with a level of shootability typically reserved for smaller calibers, making it ideal for a duty bag, vehicle, or home.
How does the KRISS Vector SDP-E G2 compare to a CMMG Banshee in 10mm?
The KRISS Vector is mechanically superior for pure recoil mitigation but less modular and more proprietary than the CMMG Banshee. The Vector's delayed blowback Super V system physically redirects recoil energy downward, which is measurably more effective than the CMMG's radial delayed blowback at taming muzzle flip with full-power 10mm loads. However, the CMMG Banshee uses a more common AR-15 control layout and accepts a wider universe of triggers, grips, and stocks without adapter kits. For a shooter prioritizing the absolute flattest shooting 10mm platform, the Vector wins; for one wanting to leverage an existing AR-15 parts bin, the CMMG Banshee is the better choice.
What does it weigh and what are the dimensions?
The SDP-E G2 has a dry weight of 6.9 pounds and an overall length of 23.4 inches with the stock folded, which is crucial for transport or storage. The critical barrel length is 5.5 inches, threading is standard 9/16"-24 TPI, and the receiver accepts full-size Glock 20/21 magazines. This compact package is heavier than some plastic-framed alternatives but the weight is concentrated in the steel upper receiver and barrel, contributing directly to its stability and reduced perceived recoil. It's about the size of a collapsed Stevens 334 Rifle but designed for a completely different ballistic purpose.
Who is this NOT for?
The KRISS Vector SDP-E G2 is a poor choice for first-time gun owners or budget-minded shooters looking for a cheap range toy. Its $1,353.99 MSRP represents a significant investment, and the 10mm ACP cartridge itself is expensive to feed, costing nearly double per round compared to 9mm. Furthermore, its unique manual of arms—including a non-reciprocating charging handle on the left side and an AR-style safety/selector—requires dedicated familiarization. If your primary goal is low-cost plinking or you're uncomfortable with a non-traditional control scheme, a more conventional pistol or a 9mm PCC like many others on the market is a wiser use of funds.
What's in the box?
Ironclad Armory ships this unit with one (1) KRISS-branded 15-round Glock-pattern magazine, flip-up front and rear M-LOK compatible sights, and the required Picatinny rail sections for the top and sides. You will not find a case, sling, or optic in the box—this is a bare-bones, ready-for-duty configuration that assumes you already have your preferred support gear. The packaging includes the necessary ATF documentation, but you must separately source your preferred muzzle device, optic, and light. Budget an additional $300-$800 for a quality red dot, suppressor-ready muzzle device, and a weapon light to make this platform mission-ready.
Is the KRISS Vector SDP-E G2 worth it at $1353.99?
At its current price point, the KRISS Vector SDP-E G2 is worth the investment *only* if you specifically need the unparalleled recoil control of the Super V system for high-volume 10mm shooting, plan to run it suppressed frequently, or require its compact folded profile. You are paying a premium for a patented mechanical solution to a specific problem—muzzle climb with a powerful pistol cartridge. If your use case is general home defense with occasional range use, a $700 9mm AR pistol and $650 worth of ammunition and training will almost certainly make you a more capable shooter. This is a specialist's tool, not a generalist's first choice.

Frequently asked questions
- Is it compatible with Glock 20 magazines?
- Yes, the KRISS Vector SDP-E G2 accepts all standard double-stack Glock 20 (10mm) and Glock 21 (.45 ACP) magazines. This includes aftermarket options from Magpul, ETS, and Glock OEM magazines with capacities ranging from the included 15-rounder up to 29-round extended magazines. The magwell is not compatible with single-stack or slimline Glock models.
- Does the threaded barrel accept a suppressor?
- Yes, the barrel is threaded 9/16"-24 TPI, which is the industry-standard pitch for .40 caliber and 10mm suppressors. You can directly thread-mount suppressors from manufacturers like SilencerCo (Omega 36M), Dead Air (Wolfman in .40 cal config), or Rugged (Obsidian 45). Always verify your specific suppressor is rated for 10mm pressure and use proper alignment tools before attaching.
- How long does direct shipping take?
- Ironclad Armory processes in-stock items like this Vector within 1-2 business days. Once the firearm ships via our contract carrier, ground transit to an FFL in the continental US typically takes 3-7 business days. The total timeline from order to arrival at your selected dealer is usually 5-10 business days, not including the time required for your FFL to conduct the mandatory NICS background check.
- Can I attach a vertical foregrip to this pistol?
- No, attaching a vertical foregrip to this firearm in its current pistol configuration would create an unregistered Any Other Weapon (AOW) under the National Firearms Act (NFA), a federal felony. The overall length is 23.4 inches. You may legally attach an angled foregrip or a handstop. To use a vertical foregrip, you must first register the firearm as a Short-Barreled Rifle (SBR) with the ATF, which involves a $200 tax stamp and a wait time averaging 60-90 days.
- Does this work with a binary trigger?
- No, the KRISS Vector's delayed blowback fire control group is proprietary and does not accept aftermarket AR-15 triggers. There are currently no commercially available binary or forced-reset trigger mechanisms (FRTs) engineered for the Vector platform. The factory trigger is a single-stage design with a pull weight averaging 6.5-7.5 pounds, and your upgrade options are limited to factory components or very niche custom smithing.
