Abstract: A perforating gun system includes a cylindrical outer housing, a charge carrier assembly receivable in the outer housing, wherein the charge carrier assembly includes a charge carrier configured to receive one or more shaped charges, a first endplate coupled to a first end of the charge carrier, and a second endplate coupled to a second end of the charge carrier, and a detonator holder incorporated into the first endplate of the charge carrier assembly and including a pair of opposed longitudinal ends, a first passage extending along a first axis and configured to receive a detonating cord, and a second passage extending parallel to, but laterally offset from, the first passage, wherein the second passage is configured to receive a detonator configured to detonate the one or more shaped charged in response to receiving a signal.
