KRISS VECTOR SDP
Posted May 19, 2023
The KRISS Vector SDP is widely considered to be the gold standard in submachine guns. While not very well known outside of the gun enthusiast community, it's been a popular choice for those looking for a reliable and highly customizable SMG. However, it's not for everyone. In this in-depth review, I will discuss the advantages and disadvantages of the KRISS Vector SDP, offering an honest opinion on whether or not I believe it is the best choice for those in search of an SMG.
The KRISS Vector SDP is a gas operated, magazine-fed, select-fire, blowback operated submachine gun designed and manufactured by KRISS USA. The SDP stands for "Standard Definition Pistol", which indicates a civilian-legal version of the KRISS Vector with a much shorter overall length to make it less maneuverable and easier to transport and conceal. The SDP was intended for use as a home-defense weapon and for personal protection.
At the core of the KRISS Vector SDP is its highly ergonomic design. It features a polymer receiver, an adjustable stock, an enlarged ergonomic pistol grip, and an M4-style drop-in handguard. These elements combine to create a weapon that is extremely comfortable to handle and shoot. The ergonomics of the SDP also lend themselves very well to use in restricted spaces such as hallways and tight rooms.
Another great feature of the KRISS Vector SDP is its ambidextrous controls. As with many modern firearms, the selector switch and magazine release are conveniently located on both sides of the lower receiver for easy manipulation with either hand. Additionally, the Vector SDP features a reversible charging handle for more flexible manipulation of the gun. This makes the SDP a great choice for left-handed shooters or those with disabilities.
The KRISS Vector SDP is also incredibly customizable. It comes with modular rails that provide plenty of options for the user to customize its look and functionality by attaching items such as lights, lasers, and sights. This makes the SDP a great choice for those who are looking to build a personalized weapon for personal defense or for those who want to customize the gun to meet their individual needs.
Another thing worth mentioning about the KRISS Vector SDP is its reliability. The Vector SDP is built to withstand the punishing demands of close quarters combat while still providing excellent performance. The Vector SDP is a rugged, dependable submachine gun that is designed to last. Additionally, the SDP is compatible with both Glock and Colt magazines, so if you don’t have the latest version, you can still use the SDP.
The Vector SDP also offers excellent accuracy for an SMG. The adjustable stock and pistol grip help the shooter to maintain a comfortable and reliable shooting platform while firing. Additionally, the SDP includes adjustable iron sights, though you may choose to attach an optic of your choice. With these features, the SDP is very well suited for target shooting and plinking.
Now that we’ve discussed some of the advantages of the KRISS Vector SDP, let’s move on to the disadvantages. The first and perhaps most obvious disadvantage is the cost. The Vector SDP is not a cheap gun. It retails for around $1,300, which may be out of the budget of some gun enthusiasts. Additionally, the SDP can be difficult to find in stock and depending on where you look, you may be hard-pressed to find a good deal on one.
The SDP requires an NFA (National Firearms Act) stamp and registration with the ATF for purchase, which can be both a hassle and costly. Furthermore, the Vector SDP is only available in 9mm and .45 ACP, which can make it difficult for shooters who want an SMG in different calibers. Finally, the Vector SDP is not made to be used with suppressors, so if you’re looking for an SMG with a suppressor, the SDP may not be the right choice for you.
Overall, the KRISS Vector SDP is an excellent option for those looking for a reliable and highly customizable SMG. It is a well-engineered and highly ergonomic weapon that is capable of excellent accuracy and reliability. The Vector SDP is also incredibly customizable, allowing for the user to tailor the gun to their individual needs.
However, the SDP is not without its drawbacks. The cost of the SDP can be prohibitively expensive, and the NFA paperwork and registration required for purchase can be a hassle. Additionally, the SDP is only available in 9mm and .45 ACP and cannot be used with suppressors.
Despite these drawbacks, I believe the KRISS Vector SDP is a great choice for those in search of an SMG. It is reliable, ergonomic, and highly customizable. The SDP offers excellent performance and is an excellent choice for those in search of a versatile and highly reliable submachine gun.
Pros & Cons
Pros:

- Flexible magazines allow the user to choose between 9mm and .45 ACP caliber which improves the versatility.

Cons:
- Expensive and hard to find gun as it is not widespread in stores.

Who Should Buy
The KRISS Vector SDP is a powerful semi-automatic firearm with a high caliber and powerful recoil which can make it difficult to manage. Therefore, the KRISS Vector SDP is not recommended for people who are inexperienced with firearms or those with limited hand strength and smaller frames. This firearm is also not ideal for those who plan on using it as a hunting weapon, since it is more of a military and law enforcement-style weapon.
For those who have experience and knowledge about firearms and a good hand strength, the KRISS Vector SDP can be an ideal choice. It is highly accurate and has a superior recoil management system which makes it well-suited for those who want a reliable high-powered firearm.

Accuracy
The KRISS Vector SDP is a highly accurate 9mm submachine gun for personal defense, security enforcement, and other applications. The gun has a maximum effective range of up to 150 metres (490 feet), combined with its low recoil and high rate of fire offering exceptional accuracy. This accuracy is further enhanced by Kriss's Super V Recoil Mitigation System which reduces felt recoil up to 70%, resulting in the least amount of muzzle rise and quicker target reacquisition. The Vector SDP also features a tight barrel to slide/bolt fit for improved accuracy and toned down recoil. All of thismakes the Vector SDP an excellent platform for personal defense and certain tactical applications.
