Well my issc was having the light strikes about once a clip. I put the washer in there and tightened that bolt that always gets loose and that worked for the first clip. From there i started getting failure to eject and light strikes after that. Hopefully and wishfully putting the longer screw and lock tight on the two will completely fix this cursed gun... first i need to find this bolt which i have had no luck locating... a lot of headaches from a gun that cost quite a bit out of the gate.
