a gun body;

a bulkhead assembly for coupling the first perforating gun to a second perforating gun, wherein the bulkhead assembly is at least partially disposed in the gun body, and wherein the bulkhead assembly comprises a bulkhead and an electrical feedthrough formed in the bulkhead; wherein the electrical feedthrough is configured to house one or more electrical connections in the perforating gun assembly;

an end alignment attached to the bulkhead assembly, wherein the end alignment engages the gun body;

an electrical contact that passes through one or more internal regions of the end alignment, wherein the electrical contact comprises a contact plate, a support plate, and three or more bends disposed between the contact plate and the support plate to counteract a force applied to the contact plate when engaged by a contact pin, wherein each one of the three or more bends does not extend past a diameter of the support plate to keep the contact plate axially located during deformation from contact with the contact pin;

a charge tube interlocked with the end alignment, wherein the charge tube holds

a plurality of perforating charges disposed in corresponding charge cases; and

a detonator housing interlocked with the charge tube; and

the second perforating gun comprising:

a charge tube interlocked with the end alignment, wherein the charge tube holds a plurality of perforating charges disposed in corresponding charge cases; and

a detonator housing interlocked with the charge tube, wherein the detonator housing of the second perforating gun is secured in the bulkhead assembly of the first perforating gun.
