I have an M&P40 with an Apex sear and it is awesome. I am very impressed with it's accuracy and so far it's reliability through plenty of rounds. The gun just operates very smoothly - much more so than the G22 I have handled and shot lately. My brother was so impressed he just picked up an M&P40 PRO 4.25 with trijicon Night Sights and WOW is it a lot of gun for the money IMO. It comes with a S&W performance center trigger job (his registered 4.5 lb brand new) and the factory night sights. The trigger on his gun is awesome and I am very impressed with the build quality. Going to the range tomorrow - I'll give an update. In my experience these are very accurate shooters.
