A protective case system includes an extendable device grip and a protective case. The extendable device grip includes an attachment mechanism and has a stowed configuration and extended configuration. The protective case includes a shell and a receiver. The shell is configured for receiving and removably retaining an electronic device. The shell has at least a back wall and side walls. The outer surface of the back wall of the shell includes a recessed or concave area. The extendable device grip is removably attachable to the receiver for removably attaching the extendable device grip to the protective case. The receiver is positioned in the recessed or concave area of the back wall of the shell such that at least a portion of the extendable device grip is within the recessed area when the extendable device grip is attached to the protective case and is in the stowed configuration.
