1. A perforating gun, comprising:
a ballistic interrupter adapted to accommodate one of a detonating cord or a detonator; and
a detonation housing adapted to accommodate the ballistic interrupter and the other one of the detonating cord or the detonator so that the ballistic interrupter is actuable from:
a disarmed state or configuration, in which the ballistic interrupter is rotationally oriented so as to provide a mechanical barrier impeding ballistic communication between:
the one of the detonating cord or the detonator accommodated within the ballistic interrupter, which ballistic interrupter is accommodated within the detonation housing; and
the other one of the detonating cord or the detonator accommodated within the detonation housing;
to
an armed state or configuration, in which the ballistic interrupter is rotationally oriented so as to permit ballistic communication between:
the one of the detonating cord or the detonator accommodated within the ballistic interrupter, which ballistic interrupter is accommodated within the detonation housing; and
the other one of the detonating cord or the detonator accommodated within the detonation housing;
wherein the ballistic interrupter comprises an exterior surface and a first bore adapted to accommodate the one of the detonating cord or the detonator.
