I've owned 6 Shields and one M&P 2.0 Compact. Owned the Compact for several years now. I never understood why anyone complained about the stock trigger as it was just fine. There's really no need to spend $100+ to replace the trigger.
I have the full APEX Competition trigger kit on my 2.0 Compact, I have the full APEX Duty/Carry kit on my Shield 45 PC, the new bladed trigger on the Shield Plus, and the traditional stock trigger on everything else. None make a bit of difference for me when putting rounds on paper. Maybe, IDK, if I shot long distances (100 yards) or something it would make a difference, but it's a self-defense pistol. At self-defense distance and common distance most fire their 4" or less small carry guns, I don't notice a difference despite the hype. Plus it's a PITA installing an APEX trigger, and I don't understand why S&W designed it so that you have to remove, reinstall, and rezero the rear sight to remove the striker block which is a requirement to install the APEX trigger kit.
@belladonna Congrats on the new M&P, go out and put a few thousand rounds through it and let the trigger break in before buying onto the hype that you need a $120 replacement.
