ABSTRACT:
A tamper proof multi-functional multipurpose safety lock is provided which will render a firearm inoperable until a person utilizes a collapsible rod key coded tool head is used to remove the safety lock. A contoured insert is placed into an ejection port on a slide when the slide is in its most rearward position. The contoured insert has a socket, so that it will accept a lug on a dummy cartridge that is carried in a magazine. When a keeper is inserted into the barrel with the collapsible rod key coded tool head, the keeper will lock the dummy cartridge to the contoured insert. Accordingly, the firearm will be completely locked up including the magazine and the slide. In firearms that do not have magazines the dummy cartridge is eliminated.
