A bi-directional explosive transfer apparatus for use in connecting and orienting perforating guns in a well. The apparatus includes a connector having first and second housing portions which are pivotally attached to one another. First and second explosive devices in the connector provide a bi-directional explosive path between perforating guns joined by the connector. At least one orienting fin is attached to the perforating guns to position the guns off-center so that they will orient themselves by gravity in a deviated well section. The swivel connection provided by the connector allows the guns to rotate individually as necessary and relative to the other guns. A method of perforating a well using the apparatus is also disclosed.
