Update:
I received my .40 compact M&P back from Dan on Saturday and couldn't be happier with the results. I purchased the Standard Trigger Job and asked him to not lower the trigger pull weight all the way down to 3.5 pounds (this is my concealed carry gun). My biggest original complaint with the trigger was the reset. It used to take several mushy clicks and a great distance of return trigger travel to reach the reset. Now, the reset is positive and much much shorter. Additionally, the pre-travel is now smooth and consistent, and the over-travel has been eliminated. I also shipped a new set of Heinie Ledge Straight Eight night sights with the gun and asked him to install them.
I have only positive thoughts about Dan's work. The trigger exceeds my expectations and all of the work seems done with great care. The gun is exceedingly more accurate than I am.
I would highly recommend Dan's services. I'm certain that I'll be sending him additional guns in the future.
