1. A hydraulic perforating gun system comprising:
a conduit, proximal and distal connectors, a coupler, and a bulkhead, wherein in a fully assembled configuration the proximal and distal connectors are included within the conduit, the coupler is at least partially included within the conduit, and the bulkhead is included within the coupler;
wherein (a)(i) the distal connector includes a distal electric contact resiliently coupled to a body of the distal connector via a distal resilient member, and (a)(ii) the proximal connector includes a proximal electric contact resiliently coupled to a body of the proximal connector via a proximal resilient member;
wherein the proximal connector includes at least one aperture to receive: (b)(i) an electrical switch to couple at least one cable that is proximal to the proximal connector to at least one cable that is distal to the proximal connector; and (b)(ii) a detonator;
wherein (c)(i) the coupler is unthreaded, (c)(ii) the bulkhead includes a bulkhead electric contact and the bulkhead electric contact includes no resilient members, welds, or seems, and (c)(iii) the bulkhead electric contact is configured to directly contact both the distal electrical contact in the fully assembled configuration and an additional proximal electrical contact of an additional perforating gun.
