I looked up the Burwell trigger job...to bad I don't have the confidence nor the tools or the experience to do all that!
I'll see how the natural break in goes. I really think this M&P is going to be a keeper so as we go down the road I'll re-evaluate getting trigger work done. Probably by someone who knows how though.
You really don't need to do the Burwell trigger job to have a nice trigger feel. I did it on a couple of mine because I'm a gun geek. Reshaping a sear is not for the faint of heart when a lifetime warranty is at stake. (That's why I have extra sears. )
