Just a couple points, in regard to a couple statements made above-

1- All magazines will not fit all pistols and function correctly, some will not even insert completely.

2- There are NO "extruded steel" magazines. The mags often referred to erroneously as "extruded" are from the Haenel design and are folded , welded, and then the outside milled to shape; the feed lips are formed before folding. There is a page or two regarding their construction that completely blows up the "extruded" nonsense with drawings in Goertz and Sturgess.
