The KARD was designed by KRISS around 2010, but the patent for its delayed blowback system was only filed in February 2016 after a six year delay.
The KARD uses a modified version of the Vector's vector delayed blowback system, in which it has a fixed barrel as opposed to a tilting barrel as seen on most pistols; this also makes it more accurate and much easier for one to install suppressors or muzzle attachments on it. The KARD lacks a moving slide, and instead has a T-shaped cocking handle on the rear of the weapon. As the pistol lacks a moving slide, optics can easily be attached on the weapon.
- The KARD is notable for appearing in the game Call of Duty: Black Ops II as the KAP-40, a somewhat heavily futurized version of the KARD with the Vector's bolt release catch on the side.
