A shaped charge for use with a perforating gun having an adapter that can couple the shaped charge with perforating gun systems of more than one size. An interference fit can couple the adapter to the open end of a shaped charge. The adapter includes a base section having an outer diameter exceeding the shaped charge outer diameter. The adapter larger diameter can be coupled to perforating gun systems formed to receive shaped charges whose outer diameters exceed the outer diameter of the shaped charge coupled to the adapter. Thus the adapter can couple a shaped charge to a perforating gun that might otherwise have fittings too large to accommodate the shaped charge.
