In Washington, I do not think this would be legal as all sales on ammo are final. Good deal there!
I picked up my 9mm Shield for $450, last year, right after they were released.

I have the Warren tactical site on the rear of my M&P 9c along with a Trijicon night site on the front, and like it a lot. I have been thinking about this set up on my Shield.

This is my old M&P 40c with the same set up.
I replaced the sear only on my M&P 9c with the Apex sear. I did a little polishing of other parts myself and I am very happy with the trigger on my M&P now!!

The question has been asked already I think. What is the intended purpose of this gun? The answer to that question will probably answer your question.
