You guys missed this revelation( maybe on the other luger board).
I'll find the thread and add a link to it.

See the picture in post # 6
I did not believe it either; but just spot check your matching DWM military lugers. They are there on the inside, bottom ledge.
Keoki pointed this out, and by jimminy - he was/is correct as usual.
I might agree with the statement about "all", as I have not looked at all side plates; but the ones of mine I checked do have them. Not talking about commercial pistols, just military.
