Even though the magazines are from a later era than your Luger... don't discard or sell them if you intend to shoot your Luger. They are about the best magazines ever made for any pistol... extruded steel instead of stamped sheetmetal... and will last a lifetime. Make sure that you keep them clean inside and out for reliablility... (Disassembly is not required or suggested) and they will serve both you and the next owner of this gun without missing a beat.
