Agreed. I've owned 7 or 8 M&P's and went back to Glock. Tired of spending money tying to fix gritty, stacking triggers.
S&W needs to do better. And don't tell me it can't be done or it's fine the way it is. It isn't.
Here is a polymer framed striker fired gun that cost at least $150 less and the trigger is MUCH better than any stock M&P.
Canik TP9SA
I've always liked the P99 series, myself. Once I'd taken my first SW99/P99 armorer class (first of 3 of them for the 99 series when the SW99/990L was in production), I ordered a SW9940 and then later a SW999c. I also carried an issued SW9940 for a few years, too. Nice gun.
My SW999c is a favorite because of its great trigger and willingness to run any of the assorted JHP duty loads I've sued over the years. Its practical accuracy is easily on a par with any of my well-used 3rd gen S&W TDA guns, and is enjoyable to run for accuracy out to 50+yds. I also like how the grip feels like it's a thin single stack, even though it uses double stack 10-rd mags.
I never tried one of the Magnum Research 99 clones (Walther-supplied frames, I believe, like the SW99's). Don't know anything about the Turkish-made Canik TP series, but they seem to be somewhat popular among enthusiasts.
I tried one of the other instructor's M&P 9 Pro 5" model, and it has a surprisingly outstanding trigger. Really light and smooth. Real tack-driver. The fellow carries it as a duty weapon. The trigger on that one was even better, right out of the box, than the M&P 9's he owns which have received aftermarket sear kits (range guns), interestingly enough.
I don't mind the Glocks for "working" guns. I own 3 of them and I'm scheduled for my 5th armorer class for Glocks later this Fall.
Lots of competition to be found in the plastic duty gun genre, and Glock is going to have to keep abreast of the demand for increasingly (reasonably) better plastic guns as the market continues to evolve.
Not bad for us consumers.
