I am anxiously waiting for my birthday present next tuesday, an M&P 9C. I have seen various youtube videos regarding field stripping, and having to push down the little lever in the magwell. Some folks use a screwdriver, some folks use the little tool attached to the outside of the magwell. Which is better to use, and is there any way to release that lever without a tool? I am an M&P newbie so I appreciate the feedback! Want to make sure I can clean her up as soon as I open the case up!
