The Walther magazines produced after the war have seven uniform circular welding spots. The floorplates have a rectangular notch, comparable to the wartime produced magazines. All of the magazines have ribbed followers that are an unfinished metal color.
The Bundeswehr (german postwar army) magazines of the 4th type were stamped on the left side of the housing with the Walther banner, the pistol designation P1 and the caliber. This type does not have a military acceptance stamp on the spine. The Bundeswehr was part of the NATO organization and therefore was required to stamp all military equipment with a so-called NATO stock number (NSN). The NSN for a P.38 magazine was 1005-12-120-0892 and was stamped on the spine. The manufacturing date is found on the bottom of the spine (month/year). The difference compared to the previous variation is that the inspection stamp was omitted.
