Therories are theories, that's why they are called theories. When I was doing the Google advanced search in German to put together the string GMSG/DDR ect I located a gentleman in Germany who was asking for the same information about a GMSG Luger. This was in November 2004. The site/forum where he posted the question was no longer in operation. No contact was possible. No answer was posted. G.van Vlimmeren, you read/write/speak German much better than I ever will, its not an easy hobby especially for a redneck like me sitting in the backwoods on a mountain with a couple of ugly dogs in North Alabama. Can you come up with a better possible combination for the meaning of GMSG stamped on a WWII era gun located in the eastblock where all manufacturing was controlled by the Russians?
I'm not saying I'm right, just can't come up with a better explanation.
