I've apexed ALL my M&Ps except my shield 45. Didn't need the sear, breaks just as good as all my apexed M&Ps. Polished the sear, USB, and trigger bar, just as smooth as my apexed M&Ps. I did add an apex trigger because of preference and the regular shield apex trigger worked fine. My guess is apex tweaked the profile a smidgen to better match the frame.

I am exactly the same. All my MP's got apexed except for my Shield .45 and PC Shield 9mm
