Thanks for the advice. I might cancel my deposit and go that route for the .40 pro if they can't get it by October.
I did get the FS .45 at a local store and love it. From most of the reviews on the M&P triggers I was expecting to order an Apex in the near future, but the stock one feels smooth as it is. Either I got lucky or I'm just ignorant of what could be better. Sometimes ignorance is bliss!
