1) They should start producing firearms the allow for 2 or 3 magazines to be inserted at once, then automatically switch over to the next magazine when the previous one is empty

2) They should make bullets be able to fire 3 or 4 bullets before they are spent,.. almost like little mini revolver cylinders .. but as bullets

3)Make belt fed handguns that the user can easily make the belt as long as they want..

any other ideas???
