TDI Kriss Super V: Unconventional submachine gun with almost no recoil

TDI Kriss Super V is an unconventional submachine gun developed by the Transformational Defense Industries (TDI). The company was rebranded and is now known as Kriss USA. This superior weapon is futuristic and uses an unconventional delayed blowback system with an in-line design to reduce perceived recoil and muzzle climb.


Newer designs and more modern technologies made TDI Kriss Super V more unique and superior to similar submachine guns, such as the HK UMP designed in 1999, which is slightly modernized and improved on the old HK MP5. What makes KRISS Vector interesting is the absorption of recoil, which makes shooting this weapon much more controllable; also, it shoots 1,500 shots per minute.

The name Kriss comes from a Southeast Asian dagger with a flame-shaped blade. After rebranding, TDI Kriss Super V has become part of the Kriss Vector, a series of weapons.


TDI Kriss Super V is a delayed-blowback, selective fire weapon that fires from the closed bolt. It is chambered for .45 ACP ammunition but is also available in .40 S&W and 9×19 mm Parabellum.

The Kriss Super V uses a patented operating system, which reduces recoil and muzzle climb. It absorbs and redirects the recoil force downwards, thus improving overall weapon control. Developers claim this submachine gun generates 60% less felt recoil and 95% less muzzle climb than contemporary designs. As a piece of mechanical engineering, it accomplishes its design goals perfectly.

This weapon can be fired single-handedly with adequate accuracy. This submachine gun has an effective range of about 100 meters. Weapons can be easily field-stripped just with the removal of two push-pins. An ambidextrous fire mode selector has semi-auto settings, two-round bursts, and full-auto. It is located in the middle of the upper receiver.

A separate ambidextrous safety switch is located above the pistol grip. Cocking handle is located on the left side of the receiver. It folds over when not used and does not reciprocate when the gun is fired. The spent case ejection window is located on the right side.

The Kriss Super V is fed from the standard 13-round Glock 21 magazines. The optional extension kit provides the 30-round capability. The magazine housing is located in front of the pistol grip. This weapon has a full-length Picatinny-type rail on top of the receiver. It accepts detachable iron sights or various sighting devices, such as red-dot sights.

This SMG comes with a side-folding polymer buttstock. Another accessory rail is mounted below the barrel and is compatible with laser pointers, vertical grips, tactical flashlights, and other accessories. Two additional rails can be installed on either side of the receiver.
