The invention relates to the field of oil and gas production. A perforating gun comprises a single-piece housing containing cavities perpendicular to its longitudinal axis, said cavities being formed directly in the material of the housing of the perforating gun. The following individually manufactured, conjoined structural parts of a shaped charge are hermetically installed directly in the cavities: an outer cap of the shaped charge; a hermetic seal in the form of a ring or gasket; a charge cavity; and a primary explosive pellet. Also disposed in the housing are: a detonation transmission amplifier; a sealing ring; a detonating cord; and a plug with a groove. A detonating cord is connected to each charge, said detonating cord being disposed in a channel formed along the outer surface of the housing and being ballistically connected via an opening to the pellet in the cavity.
