This guy does a series of three videos showing the full disassembly/reassembly of the M&P 22 Compact

He does a pretty good job with the videos. The slide is pretty generic, and easy to detail strip. In fact, it's worth stripping it to polish up the striker block. Makes a huge difference on trigger pull.
Be advised, though, the frame is a bit more complicated than, say, a FS M&P or a Glock. It can be done, but I advise watching the videos a few times to get the overall concept, and then using it as a "play-along" guide as you go.
Good luck.
