So, that said, it is illegal as hell to put a stock on a luger not originally made for it. If you look it up on the BATF or whatever the hey they are called now, you can see that artillery's, navies, 1900 with certain stocks are allowed. AND, a navy is legal on a navy, an arty on an arty, NOT vice-versa...
