I just bought this used luger 22 and downloaded the operation manual. I noticed in the instructions that the toggle is supposed to stay open when you pull it back without bullets in the clip. But mine doesn't seem to work. The only way I can make it stay open is to pull it back and put the safty on. But even when I do this it doesn't stay firmly in position. Does anyone have any idea what may be wrong with the gun. It has plastic grips and 5.5 inch and the serial is 6339.
