The Calico M950 is a semi-automatic pistol manufactured by Calico Light Weapons Systems in the United States. Its main feature, along with all the other guns of the Calico system, is that it feeds from a proprietary helical magazine mounted on top, available in a 50 or 100-round capacity. The factory sights enable accuracy to about 60 meters (197 feet), but 100 m is still a reasonable range. The M950 can be configured also as a carbine (there is space to attach a foregrip) and is chambered for 9x19mm. The company produces a Calico M-1 chambered for .22LR that is superficially similar, but does not share parts with the M950. Due to the futuristic look of Calico weapons, they have appeared in many movies.
