I'm a believer and have Apex triggers, sears and springs in my Shield 9 and my 9C. The Duty/Carry kit is a smooth and crisp 6 pounds and the FSS kit is 4.5 pounds.
The trigger is the first upgrade for accuracy, then sights, then barrel...
A F/S M&P 9 with Apex FSS kit and a good red dot sight is probably within a froghair of perfect without a fitted barrel.
