Dude,
The last time i cleaned my MP9 i noticed that the takedown lever seemed to be catching on the recoil spring or something and trying to spring back into the up position. It's never done this before, so i screwed with it a little bit to see what was going on. If i held it down and pushed down on the end of the guide rod, it would stay down, but otherwise wanted to spring back up. DIdn't seem to adversely affect anything so i left it alone. I'm interested to hear what other people have to say about it, you're the first person i've heard mention it. I guess we'll have to wait for some other input, hopefully Dan or David might chime in and let us know if we should worry.
