Thanks for the education on the FXO mag history and construction GT!

I also have a theory about the production of the feed lips. I think these tubes were cut to the appropriate shape, then the lips were hammer forged while the steel was soft, and then heat treated to the appropriate hardness just before bluing, and assembly. I can't see any other logical process to producing them... in my limited metal manufacturing process experience (2 years).

The Germans may have lost the war due to dedication to producing only quality products, but they sure made the best darn pistol mags ever made in the FXO...
