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.{{cite book|last=Peterson|first=Phillip|title=Gun Digest Buyer's Guide to Tactical Rifles|url=https://books.google.com/books?id=_TOaNipXcIkC&pg=PA32|date=15 November 2010|publisher=Gun Digest Books|location=Iola, Wisconsin|isbn=978-1-4402-1781-4|pages=32–34}} The factory sights enable accuracy to about 60 meters (197 feet), but 100 m is still a reasonable range.{{sfn|Wexler|2023|p=44}}

The M950 can be configured also as a carbine (there is space to attach a foregrip{{sfn|Wexler|2023|p=44}}) 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.{{sfn|Dougherty|2017|p=255}} Due to the futuristic look of Calico weapons, they have appeared in many movies.{{sfn|Wexler|2023|p=44}}
