Calico also has a speed loader, so that the 50 round magazine can be loaded in 15 seconds and the 100 in 30 seconds. Due to the design of the magazine, there is not spring tension problems or wear if you keep it constantly loaded as the spring relies on torsion, not compression. By redesigning the gun the spent chambers eject down, thus reducing muzzle climb. The redesign also allows for a 5 second tool-less weapon strip. The sights are on the magazine and adjustable so that you can adjust for distance and the offset between barrel and sight. So that means you can have magazines of high capacity, always loaded, ready to go and an easy gun to maintain, to boot. And the cost is very, very reasonable, to boot. Available currently in .22LR and 9mm, soon in the 40 cal. Tagline: "Running out of ammunition is a malfunction"
