A shaped charge carrier assembly includes a thin wall carrier having a charge opening disposed therethrough for freely receiving a shaped charge therein. A deformable retaining device is integrally formed with the thin wall carrier adjacent a periphery of the charge opening. The deformable retaining device allows the shaped charge to initially be freely received in the charge opening, but subsequently retains the shaped charge in the charge opening upon deformation of the deformable retaining device.

A method of assembling a shaped charge carrier apparatus for use in a perforating gun, said method comprising the steps of: (a) providing at least one shaped charge having a generally cylindrical outer surface and having first and second oppositely facing shoulders defined thereon; (b) providing a thin wall carrier having a substantially circular charge opening disposed therethrough large enough to receive said generally cylindrical outer surface of said shaped charge, said carrier further including deformable retaining means integrally formed therewith adjacent a periphery of said charge opening, and a tool receiving aperture, proximate said charge opening, disposed therethrough; (c) inserting said shaped charge into said charge opening until said first shoulder abuts said carrier; (d) inserting a thin bladed tool into said tool receiving aperture; and (e) deforming said deformable retaining means inwardly into said charge opening to thereby retain said shaped charge in said charge opening of said carrier.
