Ok, if there is something you don't understand, just ask.
TDL = take down lever
Ok, well I feel pretty comfident about my assessment of the TDL snapping back. I like not having to be a contortionist to take my M&P down. I just picked up my new M&P40c a few weeks ago, the trigger sucks in Mass.. we in Mass know what that's like... I ordered my Apec trigger kit a month ago so it's on the bench ready to install tonite. I want to just update my findings from previous M&P's I own that do not need to have me hold the TDL while removing the upper slide assembly, as I stated, I had one that the TDL wouldn't stay down and fixed it, well my new 40c won't stay down so I checked it out, found a little high spot easily seen before removing the TDL, filed it down and my TDL stays down just fine now!! There was a little bump in the middle of the lever that was black, that means it was there from it's birth and colored over. After removing the slide, remove the TDL by turning it forward past the roll pin, then remove out the left side. You may be able to turn the lever over the roll pin or you may have to drive the pin in about an 1\8th of an inch and the TDL will turn easily forward then just pull the lever out. In the middle of the flat on the forward edge there is a little nub there, file it off so the surface is flat, install and your TDL should stay down much better. The spot we need to pay attention to is where the recoil guide rod makes contact with the TDL.
hope this makes sense and helps, let me know.
