Hi fellows, I have to say this is an awesome resource for luger owners. I just bought my first pistol, of course, a 1940 Luger, mismatched shooter that was professionally reblued. If you place an empty magazine in the Luger, and pull the knee toggle and bolt all the way back, it is held there. However the takedown lever somtimes rotates downward by gravity and the trigger sideplate falls off. What, if anything, is wrong? With the knee held all tyhe way back, the barrel is not placing any force on the takedown lever, allowing it to be loose enough to rotate on its own, leaving you with a pistol beginning o fall apart in your hands. Any idea what I should do about this?
