I would like to point out there are different versions of the Pro Series. There is the regular Pro Series and the CORE Pro Series. I have a CORE Pro Series that has the new improved sear. On mine, the trigger was pretty bad. It was really gritty. I purchased the Apex Tactical AEK trigger kit and the trigger is awesome now. I also have the new "Performance Center" M&P Ported CORE. The trigger on it out of the box is way better than my stock Pro Series CORE was. My Performance Center CORE trigger is as good or better than my Pro Series CORE with Apex parts. I think a lot of people get the regular Pro Series, the Pro Series CORE, the Performance Center Ported CORE (newest and best), and the regular Performance Center M&P models mixed up.
