They are not crimped on the sides, but where is the seam?

The seam is on the back. Like the P08 mags you illustrated, they are formed around a mandrel, welded on the back seam, and the weld ground flat. If you remove or push down the follower, you can see the unground inner seam. The outer seam is ground lengthwise and left unpolished.
