The Calico M950 is a semi-automatic pistol (and can also be classified as a carbine-type weapon), manufactured by Calico Light Weapons Systems in the USA. Its main feature, along with all the other guns of the Calico system, is to feed from a proprietary helical magazine mounted on top, available in 50-rounds or 100-rounds capacity. The Calico has enough barrel to enable enough room to allow a two handed foregrip which is more suited to a submachine gun or a rifle. The long barrel on the M950 allows it to accurate to about 60 metres (197 feet). It can be also chambered to take .22LR
