The PS90 provides a compact lightweight and completely ambidextrous firearm capable of fulfilling numerous security personal defense competition and recreational shooting roles. Fired cases are ejected downward where they cannot interfere with the user. The extended 16.04 barrel and closed bolt operation give the PS90 outstanding accuracy while the non magnifying optical sight makes it easy to locate and stay on a target. Recoil is reduced by the integral muzzle break.
