Why is automatic pistol cartridge case so long?

It regulates the pressure. The extra space inside the cartridge helps the gasses that form during ignition to expand to a certain level before forcing the round out and into the barrel. It also acts as a fail safe that prevents that gas pressure inside the cartridge will become too high with unwanted effects on the pistol and shooter. At least, that's my point of view and it may be horribly wrong
