Design

The Vector's patented action was originally designed by French engineer Renaud Kerbrat. This action, the so-called Kriss Super V, is an articulated mechanism which allows the block and bolt to recoil off-axis into a recess behind the weapon's magazine well. The Vector series are the first to use this action; the company claims the .45 ACP chambering was chosen to demonstrate that the action could "tame" such a powerful round.

The Vector's barrel is in line with the shooter's shoulder as in the M16 rifle and German FG42, but also in line with the shooter's hand as with many target pistols. Combined, these factors are claimed to reduce felt recoil and muzzle climb by eliminating the distance between the shooter's hand and the bore axis.
