Got mine yesterday as well, I went for the 5" FDE.  Haven't had a chance to fire it yet, did a lot of dry firing and while the trigger is much improved, my Apex'd out 1.0 was better.

Here are the changes I made as soon as I got home last night:
-Pulled the manual safety out, S&W is sending me some FDE frame plugs for free.  I forgot how much I hate the M&P external safety because of how far I choke up on the gun...
-Swapped out the sear block for one that I had radiused and polished, and I polished the trigger bar ramp where it contacts the sear block. This eliminated all of the grit on the take-up.
-Swapped out a spare Apex FSS trigger that I had.  The trigger stop limited the travel too much, so I thinned up the rear of the Apex trigger on the mill until the sear would break with very little overtravel.  (you need SOME overtravel for reliability)  I kept the factory trigger bar spring, sear and sear spring.

Trigger is now the best I've ever had in a polymer gun.

I also knocked down the texture on the backstraps a tiny bit right in the thumb web and index finger base knuckle area. I like the texture, but it was a little too abrupt in the transition to the frame.
A quick pass with a torch knocked off the fuzz so it all matches.

I'll get some pictures and range results later

I like it
Texture is great, trigger is great, M/L backstrap is great.

Here is 15yd with my wrists on the bench.  My old fullsize would print groups 3-4x as big with random fliers beyond that.
Bottom left was first shots with the gun.  Bottom right is Winchester T&D training 147gr, obviously not this gun's favorite.
When I get more time I'll run some more variety through it.  I'm most curious about my HST 147gr.

Ifi bought one it would be the FDE 5"

That being said the trigger was still meh and reminded me of why I sold my 1st gen.

Put my name on the waiting list for a 2.0 5" in FDE. Gonna give the external safety a whirl and see if it needs to go. This is my first M&P, always went for Glock before. But that tan 5" really grabbed me for some reason. Can't wait for the calll.

My 2.0 5inch fde came in. All i can say is wow. Love it. Trigger is a little gritty but not near as mushy as the 1.0. Reset could be a little shorter. The grip is awesome. I will be adding a 4.25 and a 5 in black pending how this one pans out after a few K.

Looks like a nice upgrade.

Can anyone tell me what the two cutouts are for directly above the rail?

Will ther be a 5" without a safety? If so, anyone know when?
