Imported as a pistol, it is a blowback-operated semi-auto in 9mm with a short 7¾” barrel. Equipped with CZ's newly designed low-profile sights, its rear sight has four different aperture sizes for everything from close quarters to way out there. The sights ride on an 11” Picatinny rail perfect for mounting optics. Starting in 2016, Scorpion Pistols feature 1/2×28 threads hidden underneath the factory flash-hider, meaning users can fit either 1/2×28 or 18×1 accessories to the muzzle. Also added is a QD sling swivel pocket integrated into the rear sling attachment point. Simple and reliable, the Scorpion not only has ambidextrous controls, its non-reciprocating charging handle is swappable and reach to the trigger is adjustable.
