Thanks for all the comments. I have requested this thread be added to the Notable Thread Index you'll see at the top of the M&P Pistol forum. Hopefully, handejector will add it there.
I have sent the PDF to a number of people. I hope it helps.

What would be ideal is that the PDF gets posted as a "sticky" so that it could be downloaded directly from the site. I'm thinking that the top of the "M&P" section would be the place. It's only a 260Kb file so it's not all that big. I appreciate your work on doing this and sending me the file but you shouldn't be bombarded with requests to send the file. (unless you want to, in that case, "never mind", to quote Rosanne Rosanna Danna
) That way your time would be freed up for even more interesting projects.

I probably should have put the little copyright thing on it, but that's OK with me and it will save my inbox.

Cool great work. Needs to be a sticky for sure.

Thanks Louchia.
If I had an M&P .22, I would do this for that as well. Alas, I do not have one.

Here's a Brownell's M&P Schematic I bookmarked and refer to as well, which links back to parts (from Brownell's, of course). Helpful when looking for part #'s...

Thanks for that link 78Staff. Here's the diagram:
These exploded diagrams are great. They show all the parts. The reason I posted the pics the way I did was to show the parts as they look on the gun. It's easier for some to find them by looking at the already assembled gun.
I did use the above to update the nomenclature for two parts in the magazine. The OP has been modified to show the correct names.

Bear in mind when using older diagrams, even when used with permission of the manufacturer, you may not be seeing the most current revisions of some parts & assemblies.
For example, in the linked diagram it appears the "standard" ILS locking block and the then-optional no-lock (ILS) sear housing blocks are shown, and the thumb safety version isn't shown. There came a point, when S&W was being deluged for requests for the thumb safety option, that they decided to make the thumb safety sear housing block the "standard" assembly. That way it could be used for both models, with & without thumb safeties. The ILS SHB is still available, last I heard, as special order.
Also, the original MA-compliant sear housing block, with its larger sear plunger and spring, became the "standard" (replacing the original SHB with its much smaller plunger & spring). Since there are a lot of the original M&P's, with the original SHB's, out there in the field, armorers are taught to recognize the differences so they can service and support both types.
Another revision not visible in the diagram is the new striker design, which started being incrementally incorporated into production sometime back in 2010, as I recall. It required a change in the spring keeper, going from the small 2-piece design to a 1-piece design (with an open space facing upward when installed).
The change from the 2 separate keepers to the single keeper was because of the design change to the striker.
More recently, the firing pin safety block (plunger) spring and its separate spring plate have been revised to make them a 1-piece assembly when shipped.
That was a welcome change, as the spring plate acquired the nickname "UFO" early on when it often went sailing through the room while an armorer student was trying to hold it properly positioned over the spring while replacing the rear sight base.
