The KRISS Vector[4] is a series of weapons based upon the parent submachine gun design developed by the American company KRISS USA, formerly Transformational Defense Industries (TDI).
Designed in 2006 and seeing limited production since 2009, the KRISS Vector uses an unconventional delayed blowback system combined with in-line design to reduce perceived recoil and muzzle climb, invented by French engineer Renaud Kerbrat.[5] The weapon is designed to accept extendedGlock magazines and fires a variety of pistol cartridges.
History
KRISS Vector SMG on a shooting range at the 2010 SHOT Show
In the spring of 2007, TDI announced their development of a new submachine gun. It was an experimental weapon under advanced stages of development at that time.
The second generation prototype of the Vector, called the K10, was announced at 2011 SHOT Show. It is a slightly more compact version of the Vector that is based on the same Super V system.
The main difference is a redesign of the lower receiver intended for easy caliber interchangeability; utilizing just a single takedown pin, users can change between 9×19mm, .40 S&W and .45 ACP by mounting different lower receivers. This also brought a redesign of the charging handle, which now travels diagonally, almost vertically, and can be mounted on either side of the weapon.
Other notable differences were a new telescoping stock instead of a folding one, and a four-sided accessory rail tube around the barrel.[8] The K10 was not displayed after SHOT Show 2013 and its status is unknown and likely has been canceled.
Kriss announced "Gen II" versions of the original Vector models in 2015. These feature a redesigned pistol grip, trigger, safety selector, and compatibility with a new 9×19mm lower. These appear to have replaced the K10 prototypes, though no features from the K10 were carried over.[citation needed]
Design
KRISS Vector CRB Generation 1 with the stock folded, and standard barrel shroud (not a functioning suppressor)
The Vector uses an articulated mechanism referred to as the "Kriss Super V", which allows the bolt and an inertia block to move downward into a recess behind the magazine well.[9]
The theory is that at the end of this travel, the energy is transmitted downward rather than rearward, thus reducing the felt recoil. When fired, the barrel axis is in line with the shoulder as in the M16 rifle, but also in line with the shooter's hand.
This is intended to reduce muzzle climb when combined with the off-axis bolt travel, though it also greatly raises the sight line in comparison to the bore axis. The initial prototype model by TDI achieved a rate of fire of 1,500 rounds per minute, though this was brought down to around 1,200 rounds per minute on the production models. Civilian models are limited to semi-automatic only.
The Vector is split into two major assemblies in a similar manner to theAR-15rifle, secured together with four push pins. Due to the weapon's unusual layout, the lower contains the action, charging handle, magazine well and barrel, while the upper contains the ejection port, rail system, pistol grip and fire control components, as well as the stock for configurations that have one. This modular design allows for toolless caliber conversions by swapping out only the lower.
The Vector's safety is ambidextrous (as well as the fire mode selector on the auto trigger pack) while the ejection port, charging handle, bolt release catch and magazine release are not, and are only available in a right-handed configuration.
Calibers such as .22 LR, .40 S&W and 9×19mm Parabellum were mentioned when the gun was first released. The Generation II versions with multiple design changes including a new 9mm variant were confirmed at SHOT Show 2015, though the .22LR version had yet to materialize and was thought to have been canceled up until SHOT Show 2020, when they announced its release.[10]
Vectors chambered in .45 ACP are designed to accept standard Glock 21 pistol magazines. A special "MagEx 30"[11] kit was available to convert a factory 13-round .45 ACP Glock magazine to an extended high-capacity version, but was later marketed as a "25+" round kit.[3]
Vectors chambered in 9×19mm Parabellum use standard Glock 17 magazines. In 2019, KRISS released the "MagEx2" which extends the capacity of a factory standard Glock Magazine. The MagEx 2 is available in 9mm for an overall capacity of 40 rounds, 33 rounds of 10mm and 30 rounds of .45 ACP.
Variants
The KRISS Vector has undergone two generations of modification. The Gen I version is the baseline model of the Vector family. It was later replaced by the improved Gen II version which features a redesigned pistol grip and trigger and has the swing angle of the safety lever reduced from 120 to 45 degrees.
It also eliminates the opening above the barrel for the original weapon's optional Surefire weapon light, since these are no longer manufactured.[12] In addition to the original Flat Black finish, optional factory Cerakote coatings now come in Olive Drab (green), Flat Dark Earth (tan), Alpine (white), or Combat Gray.
The Vector SMG variant is only available for military and law enforcement use. It features a 5.5-inch barrel (with an option of a 6.5-inch barrel on the Gen II version), a folding stock, flip-up Midwest Industries back-up iron sights (BUIS) (KRISS Sights on Gen II weapons), a full-length Picatinny rail for mounting various optics/scopes, and either two mode fire selector (single and full-auto) or a three mode fire selector (single, two-round burst and full-auto).
It is only sold as a complete weapon in .45 ACP and 9×19mm Parabellum; Due to the nature of the weapon the auto trigger pack is not compatible with any Vector lower. The 9mm model uses Glock 17-compatible magazines (typically the extended 33-rounder used by the Glock 18) and the .45-caliber model uses Glock 21 magazines.
Semi-automatic variants are produced and available for the US civilian market. There are three main configurations, the Vector CRB, Vector SBR and Vector SDP. In addition to 9×19mm Parabellum and .45 ACP, they can also be chambered in .40 S&W (using Glock 22 magazines), 10mm Auto (using Glock 20 magazines), or .357 SIG (using Glock 31 magazines).
A variant chambered for 9×21mm IMI that feeds from standard 9×19mm Glock 17 magazines is available for the Italian civilian market. The .22 LR variant feeds from a proprietary 10-round magazine, and functions using a traditional straight blowback operating system rather than the Super V delayed system.
The Canadian (and some American) civil market versions only come with the blocked 10-round magazines rather than the full capacity magazines. Like the Law Enforcement / Military SMG models, the civilian model Vectors can be converted to chamber and fire other calibers if the lower receiver groups are changed.
KRISS Vector CRB 18.6 inch barrel (Canadian version)
The Vector CRB (carbine) is a semi-automatic carbine with a permanently affixed barrel shroud to the standard 5.5-inch barrel, extending it to 16-inch (410mm), intended for states with short-barrel rifle bans, with an 18.6-inch (470mm) version produced for the Canadian market. The standard model has a folding stock (fixed in states where state law prohibits). Variants exist for compliance with various state gun laws, including a California-legal "featureless" variant with a Kydex grip-wrap barrier (prohibits gripping the back of the pistol grip), a hand stop replacing the usual vertical foregrip, and a permanently affixed Defiance DS150 stock to give an overall length of 36.5-inch (930mm).
The Vector SBR (Short Barrel Rifle) is a semi-automatic short-barreled configuration featuring the same 5.5-inch barrel as the selective fire submachine gun.
The Vector SDP (Special Duty Pistol) is a semi-automatic pistol configuration that has a permanently affixed cap with a sling mount in place of a folding stock. There is also a configuration of the Vector SDP fitted with an SB Tactical arm brace called the Vector SDP-SB (Special Duty Pistol – Stabilizing Brace).[13]
The "Enhanced" versions of the Gen II CRB and SBR are also available with collapsing M4-style stock adaptors instead of the standard folding stock (with a Magpul UBR stock included) and a rectangular barrel shroud for the CRB, though these accessories can also be purchased separately.
Derivatives
KRISS announced development of a semi-automatic pistol called the "KRISS KARD" in 2010, using the Super V system in a much smaller package to minimize recoil and muzzle rise in 9×19mm Parabellum and .45 ACP calibers. It does not have a blowback slide, instead it has a T-shaped cocking handle on the rear.[14]
As TDI, KRISS also announced a 12-gauge shotgun called the MVS and a .50 BMGheavy machine gun using a double Super V mechanism called the "Disraptor,"[15] but the Disraptor has not been mentioned since their name change, while the MVS was removed from the TDI website in late 2009.
A machine pistol is a handgun that is capable of fully automatic fire, including stockless handgun-style submachine guns.
A submachine gun (SMG) is a magazine-fed automatic carbine designed to fire handgun cartridges. The term "submachine gun" was coined by John T. Thompson, the inventor of the Thompson submachine gun, to describe its design concept as an automatic firearm with notably less firepower than a machine gun. As a machine gun must fire rifle cartridges to be classified as such, submachine guns are not considered machine guns.
The Uzi is a family of Israeli open-bolt, blowback-operated submachine guns and machine pistols first designed by Major Uziel "Uzi" Gal in the late 1940s, shortly after the establishment of the State of Israel. It is one of the first weapons to incorporate a telescoping bolt design, which allows the magazine to be housed in the pistol grip for a shorter weapon.
The Military Armament Corporation Model 10, officially abbreviated as "M10" or "M-10", and more commonly known as the MAC-10, is a compact, blowback operated machine pistol/submachine gun that was developed by Gordon Ingram in 1964. It is chambered in either .45 ACP or 9mm. A two-stage suppressor by Sionics was designed for the MAC-10, which not only abates the noise created but makes it easier to control on full automatic.
The .40 S&W (10.2×22mm) is a rimless pistol cartridge developed jointly by American firearms manufacturers Smith & Wesson and Winchester in 1990. The .40 S&W was developed as a law enforcement cartridge designed to duplicate performance of the Federal Bureau of Investigation's (FBI) reduced-velocity 10mm Auto cartridge which could be retrofitted into medium-frame semi-automatic handguns. It uses 0.40-inch-diameter (10 mm) bullets ranging in weight from 105 to 200 grains.
The .380 ACP, also known as .380 Auto, .380 Automatic, or 9×17mm, is a rimless, straight-walled pistol cartridge that was developed by firearms designer John Moses Browning. The cartridge headspaces on the mouth of the case. It was introduced in 1908 by Colt, for use in its new Colt Model 1903 Pocket Hammerless semi-automatic, and has been a popular self-defense cartridge ever since, seeing wide use in numerous handguns. Other names for .380 ACP include 9mm Browning, 9mm Corto, 9mm Kurz, 9mm Short, and 9mm Browning Court. It should not be confused with .38 ACP. The .380 ACP does not strictly conform to cartridge naming conventions, named after the diameter of the bullet, as the actual bullet diameter of the .380 ACP is .355 inches.
The 9×19mm Parabellum is a rimless, centerfire, tapered firearms cartridge.
The .38 Super, also known as .38 Super Auto, .38 Super Automatic, .38 Super Automatic +P , .38 Super +P , or 9×23mmSR, is a pistol cartridge that fires a 0.356-inch-diameter (9.04 mm) bullet. It was introduced in the late 1920s as a higher pressure loading of the .38 ACP, also known as .38 Auto. The older .38 ACP cartridge propels a 130-grain (8.4 g) bullet at 1,050 ft/s (320.0 m/s), whereas the .38 Super pushes the same bullet at 1,280 ft/s (390.1 m/s). The .38 Super has gained distinction as the caliber of choice for many top practical shooting competitors; it remains one of the dominant calibers in IPSC competition.
Hi-Point Firearms, also known as Strassell's Machine, Inc, is an American firearms manufacturer based in Mansfield, Ohio. All of their firearms are manufactured in several different locations in Ohio.
Star Bonifacio Echeverria, S.A. was a manufacturer of small arms in the Basque region of Spain from about 1905 until 1997.
The Tanfoglio Force, also known as Force 99, Force 2002, EAA Witness Polymer or EAA Witness P-Carry, is a modified clone of the Czech CZ-75/CZ-85 semi-automatic pistol. It is made in Gardone Val Trompia near Brescia, Italy by Fratelli Tanfoglio S.N.C.
A handgun is a firearm designed to be usable with only one hand. It is distinguished from a long barreled gun which needs to be held by both hands and braced against the shoulder. Handguns have shorter effective ranges compared to long guns, and are much harder to shoot accurately. While most early handguns are single-shot pistols, the two most common types of handguns used in modern times are revolvers and semi-automatic pistols, although other handguns such as derringers and machine pistols also see infrequent usage.
The Smith & Wesson SW series, most commonly referred to as the Smith & Wesson Sigma, was Smith & Wesson's first venture into using synthetic materials in pistol construction, with high-strength polymer material for the frame.

The KRISS KARD is a prototype of a semi-automatic pistol developed by KRISS USA. It is chambered in .45 ACP, and utilizes the same Super V System as the KRISS Vector, but in a much smaller package to minimize recoil and muzzle rise. It does not have a blowback slide; instead, it has a T-shaped cocking handle on the rear.
The SIG MPX is a gas-operated submachine gun designed and manufactured by SIG Sauer, and is primarily chambered in 9×19mm Parabellum. It is a gas-operated firearm featuring a closed, rotating bolt. These design features, rare in submachine guns, were chosen to enhance the safety of the user and to have a more reliable firearm. It was designed in 2013 and was released to the general public in 2015. It features the SIG Sauer short stroke push-rod gas system to reduce the recoil and improve the reliability of the weapon.
The B&T APC is a submachine gun produced and manufactured by B&T of Switzerland. Announced in 2011, the standard series uses standard 9×19mm (APC9), .40 S&W (APC40), 10mm Auto (APC10), and .45 ACP (APC45) ammunition.
