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.
The weight, which tilts downwards during recoil, provides the same functionality of inertia as a slide on conventional pistols.
A recoil spring pulls the bolt back into battery and strips a round off the magazine on its return, ready for firing.
Due to the fact there is no slide present, optical attachments can be more easily installed on the weapon.
Any other calibers it will be chambered in (like 9 x 19mm Parabellum or .40 Smith & Wesson) will most likely use standard Glock magazines as well.
