Bob, The spring in a Schmeisser designed PO8 mag should be the zig-zag type versis the coil type with spring guide in the folded mags. I don't recommend interchanging them, as the tubes are really designed for one type. The retaining pin on the schmeissers passes thru the center of the finger pull area and are generally peened over on most military mags (different pin on Police type) and the rim on one side should be removed before trying to drift out the pin.
