Abstract: An improved perforating gun. The perforating gun includes an internal charge holder formed from a conductive material and comprising a grounding tab. The grounding tab protrudes through a first end cap and is in direct electrical contact with a tandem for grounding the internal charge holder. An optional second grounding tab protrudes through a second end cap and is in direct electrical contact with a second tandem. Each end cap includes a contact pin that engages a signal transfer pin contained within a tandem. The contact pins are biased outwardly by respective compression springs, and each compression spring comprises a portion of an electrical path for a firing signal.
