I must have gotten the M&P40 1.0 FS with the worst trigger that ever left the factory.
Before I bought it I had fired several different Glocks and was convinced it was not possible for any pistol to have worse triggers. In the case of my M&P, I was wrong - and by no small margin. But as Mr. Moore says, they didn't intend it for shooters interested in precision, and that likely explains why so many trigger components are available on the secondary market. Just make the darned trigger usable to start with! Finishing of metal parts is fully understood and with modern techniques not terribly expensive.
