16. A method for deploying a perforating gun in a well, comprising:
assembling the perforating gun comprising:
selecting a plurality of modular perforating gun sections to establish a desired length of the perforating gun, each of the plurality of modular perforating gun sections having a central axis, a connector positioned on a planar first end wall and protruding outwardly therefrom along the central axis, an opening positioned on a planar second end wall, and at least one charge holder and charge retainer to receive and retain a corresponding shaped charge,
positioning the first end wall of a first modular perforating gun section of the plurality of modular perforating gun sections proximate to the second end wall of a second modular perforating gun section of the plurality of modular perforating gun sections,
aligning the connector of the first modular perforating gun section with the opening positioned on the second end wall of the second modular perforating gun section,
moving the first modular perforating gun section toward the second modular perforating gun section along the central axis until the connector of the first modular perforating gun section is received within the opening of the second modular perforating gun section, wherein the connector includes a hook that engages a protrusion positioned on an interior surface of the second end wall, thereby coupling the first modular perforating gun section and the second modular perforating gun section together; and
deploying the perforating gun downhole in the well using a conveyance.
