I am not posting this because I don't know how to take down my MP 9 but what I don't know is how to do it the wrong way. I mean, reading these posts I have seen lots of people who field strip their gun by turning the take down lever and pulling the trigger?? I have no idea how this works because I have tried it and it doesn't seem to work. What am I doing wrong?? I have a mp9 with a mag safety. Please help.
