New M&P trigger from hell

The most likely cause is you're using your gauge improperly.
You said you measured anywhere from 8lbs to 10lbs. A 2lb swing is extremely unlikely. The M&P isn't the most consistent on the market, but that's almost impossible.
You are not the first to have this problem. It has to do with the way a trigger pull gauge is used and the weird hinged trigger on the M&P. If you try to pull the trigger gauge straight back, parallel with the slide, it doesn't move the lower part of the trigger enough. Thus the trigger safety tang gets partially caught on the frame.
Try measuring it again. This time, take out all the slack first before you start pulling on the gauge. I'll bet you get a most consistent measurement.

Here is a pic of what I'm talking about:
Good observation and advice on using any trigger gauge on a trigger with a safety in it.
My M&P experience was the same as the OP's. It's easy to feel the difference between a 6 lb. trigger and an 8-9 lb. one. The gauge is used to confirm there is a problem. My factory trigger was around 9.5 lbs. on most pulls, but varied lighter at times on my Lyman digital gauge, although not as much as the OP's variance. Noticeably too heavy, inconsistent and gritty. Just all-around bad.

I know your "pain". I bought an M&P 40 a few years back. It was my first striker fired gun and I hated it for all the reasons you gave except I had no trigger gauge to verify the pull weight. I especially didn't like the mushy/gritty trigger. I researched many forum posts looking for a definitive answer and of course didn't find anything - the Apex triggers were just newly out and there weren't many reviews.
I decided to give it some time. I took it apart and did a polish job with Flitz and a cloth wrapped around my finger and then a very soft wheel on a Dremel. I paid particular attention to the edges of the striker block and it's corresponding part on the trigger bar. Then I lubed it well, did a lot of dry fire while I watched TV and went out and shot it a lot.
I now have over 3000 rounds thru it and I am well satisfied with it. By the time I had 500 rounds thru it I could really tell the difference. I can still feel the trigger bar pass over the striker block during the take up (but now it's smooth) - I consider this to be like a 2 stage trigger because I know right after passing over the striker block the next pressure is going to result in a crisp fire.
There are many you-tube vids on how to do a fluff&buff/0.25 trigger job if you're interested. I know a fluff&buff and 400 rounds are not going to take 4 lbs out of the trigger, but as suggested above I would sure shoot it some before spending a lot of $ on it or giving up on this fine weapon.
Just my $0.02. - thud
