    Abstract: A method and apparatus for a perforating gun having a movable detonator holder in a first perforating gun that is positioned inside the carrier such that the detonator is not directly positioned end to end nor side by side with the detonating cord in the loading tube. When a second perforating gun is screwed onto the first perforating gun, the entire charge tube assembly moves, closing the detonator holder further into the carrier such that the detonating holder closes in on the detonating cord until the detonator is adjacent to the detonating cord to connect the detonator to detonating cord ballistic train.
