I would be all over the M&P if it wasn't for the 2 piece trigger. There have been PD training reports reports, and even pictures on the net, of the trigger itself breaking. IIRC, San Antonio PD had some issues with trigger breakage when recruits pulled too hard . IMHO, the trigger is way to flimsy and due to this and thus don't consider the M&P a credilbe candidate for self defense.
