Embodiments may take the form of a perforating gun of modular assembly. The perforating gun may include at least one centralizing member at an interface between a loading tube and a carrier. Among modular components, the gun may also include an initiator assembly module that is electrically coupled to a modular feedthrough with a connector. The insert and the centralizing member may enhance axial cohesiveness of the modular gun. A shock absorbing mount may be located within the carrier and may receiving the initiator assembly module to provide added axial cohesiveness to the modular gun.

Cohesively enhanced modular perforating gun

A wellbore perforating device includes at least one perforating charge and an initiator. The initiator can include a ballistic train adapted to fire the at least one perforating charge. The ballistic train can include a detonator and a detonator cord. A ballistic interrupt shutter can be disposed between the detonator and the detonator cord. The ballistic interrupt shutter can prevent firing of the detonator cord.
