I just started putting on the Apex Duty/Carry Action Enhancement Kit on my M&P9. I got the hard sear, new sear return spring and new trigger spring done tonight. I would have also put in the new striker block if I could have gotten the rear sight off ... I think they welded mine on.
Anyways, without upgrading the striker block yet, the trigger feels much better already (dry fire tests only so far). I am really impressed. I always liked the M&P but the trigger is now really crisp and the reset is short and obvious. It is a noticeable improvement. The new striker block should smooth it out even more I expect.
I should get out to the range tomorrow to give it a run through (and to see if the guys there can help loosen/remove the rear sight so I can finish off the upgrade).
