Just bought a M&P pro in 9mm and was dissapointed in the trigger, was better than my stock 40 but not as good as I had hoped for. +1 on the APEX kit, I went with the competion kit as this is my IDPA gun. I was hoping for less travel in the trigger but it now breaks alot cleaner when it gets there. There where 3 distinct stopping points before the trigger breaks, now it is like it should be. The reset is much better also. I can't say VS a Smiths job as I haven't shot one a smith has worked on. But for the money this was a good route for me. I have also installed a set of Dawson Precision adj rear sights and fiber optic front. I can't say enough about how impressed I am with the product. My reloads 124 gr. lead flat nose where grouping very well but about 4 inches low at 20 yards.
