The Calico series are submachine guns (along with the civilian semi-automatic pistol and carbine versions) produced by Calico Light Weapons Systems. The M100/M110 series are fire .22 Long Rifle rounds, while the M750/M900/M950/M960 series fire 9x19mm. The 9x19mm versions were later renamed the Calico Liberty I, II, and III. All versions use proprietary helical box magazines with a capacity of 50 or 100 rounds mounted on top, and shell casings are ejected out the bottom similar to the FN P90.
