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 shaped charge carrier assembly apparatus for use in a perforating gun, comprising: at least one shaped charge including an outer case, said case having a generally cylindrical outer surface joined by a first inwardly tapered surface which is joined by a second inwardly tapered surface extending to an end of said shaped charge; inner charge holder means for receiving said second inwardly tapered surface of said shaped charge outer case and providing support to said shaped charge; a tubular thin wall carrier with a substantially circular cross-section and having a substantially circular charge opening disposed therethrough large enough to receive said shaped charge outer case, deformable retaining means, permanently attached to said carrier adjacent a periphery of said charge opening, for engaging said shaped charge at an end opposite said second tapered surface upon deformation of said deformable retaining means to thereby retain said shaped charge in said charge opening; and at least one tool insertion aperture, disposed through said carrier, adjacent said deformable retaining means so that said deformable retaining means is at least partially defined between one of said tool insertion aperture and said charge opening.
