There are step-wise pictures of the process in a couple different luger books.

One can often see the welded seam if you look inside the magazine, and often there is a slight discoloration in the finish on the outside.

The luger collector community should/would/need to stop promulgating the myth of "extruded" magazines!

Please.

Don, you're describing the construction of the typical FXO mags that don't have a folded rib/seam on each side, right? The blued mag body in the pics seems to have ribs, plus a crimp (follower stop).. The externally machined mag bodies mistakenly called "extruded" are also cut square on the bottom and have no visible holes for retaining pins.
