Despite what some think, S&W did MA residents a huge favor by putting the miserable trigger on the MA M&Ps. Some have suggested that S&W shafted the MA residents by putting a band-aid trigger that has very inconsistent and excessively heavy pulls on the MA guns. I say nonsense.
S&W put another series of quality guns on the MA market. That's the important thing. With all the money that gun manufacturers get raped out of by MA with all the testing BS, S&W found a quick cheap way to get the M&P MA approved. They did it by putting a cheap crap quick fix trigger on it. S&W, I'm sure knew that anyone in MA that really wanted an M&P would spend $60 more and get a trigger job. Even if S&W put a consistent 10lb trigger on them, 99% of the buyers would still go right out and shave it down to 5-5.5 at least.
Any way you slice it, the 10+lb MA trigger is gonna need work so who cares if it's 10lbs or 30? Either way or anywhere in between, Gregg Derr will fix it right for you.
