All that is needed to make the trigger really awesome on the newer guns is to polish the internal metal parts that are metal on metal. I did that on my sons 9mm M&P and my friends 40. It's honestly as good as the Apex trigger now.
There is a YouTube video that shows a guy polishing the parts. Search M&P DIY trigger job.
No need to file the sear on the newer guns though.
