Haenel- Schmeisser magazines are discussed at length (and I mean at length, 12 pages!) in "Pistole Parabellum" by Görtz/Sturgess. To begin with, they are not extruded. They are stamped, folded, and almost invisibly welded along their spines. With the introduction of the stronger zig-zag spring the base retaining pin had to be "relocated to an almost central position in the finger grips which eliminated the possibility that the base might work loose through non-symetrical leverage exerted by the spring. This relocation of the base pin to the center line of the magazine body necessitated the lower end of the magazine body being reprofiled to a right angle". I hope this helps. Regards, Norm
