1. A method of perforating a well, comprising:
connecting a string of perforating guns end to end, including positioning a first end of a connector body within a first perforating gun, with a pin carried on the connector body coupled to a signal conductor of the first perforating gun, positioning an opposing second end of the connector body within an adjacent second perforating gun to engage the pin with an electrical contact structure of the second perforating gun, the electrical contact structure coupled to a signal conductor of the second perforating gun, the electrical contact structure including a free end with a contact tab aligned for engagement by the pin upon positioning the second end of the connector body within the second perforating gun and a spring element unitarily formed with the contact tab for elastically deforming in response to engagement by the pin;
suspending the string of perforating guns on a conveyance into the well along a section to be perforated;
transmitting a signal down the conveyance to the first perforating gun and through the pin to the electrical contact structure of the second perforating gun to select which of the perforating guns to fire; and
firing one or more shaped charges in each of the selected perforating guns in response to the signal.
