CZ's Scorpion EVO 3 S1 pistol utilizes the carbine-model's extended, slim profile forend that will hide most 9mm and hybrid cans, while offering M-LOK attachment points and boosting the sight radius a good deal. Low-profile aluminum adjustable sights round out the platform, with a rear sight featuring four different aperture sizes, and a top Picatinny rail for mounting optics. The Scorpion line has a fiber-reinforced polymer frame with an ambidextrous safety. The black polymer pistol grip is adjustable for trigger reach. It still uses the 7.72" cold hammer-forged barrel of the standard Scorpion pistol with a muzzle featuring dual threads of 18x1 and 1/2x28 to make fitting a suppressor simple. Note: Current production Scorpion pistols lack the .75" sling slot on the left side of the action that is present on earlier variants. This model features a 5" KAK Flash Can which extends the barrel to just a hair past the forend. It includes a 20-round magazine.
