free state version of the M&P 2.0 has a very nice trigger. i'm please with mine. like other M&P's the striker develops a burr after ~1500 rds that results in the trigger becoming gritty. a quick polish job removes the burr. it seems to be caused by the striker moving over the sear when the slide goes rearward.
i overall really dig my 2.0, much more than i thought i would. that being said both the 2.0's sear design and the slide stop mechanism appear more complex than the original design. no matter how well designed, increased complexity is a bad thing. but if i stop thinking so hard and just shoot the thing, I find it's phenomenal at the range. if you really want a 2.0 just get a free state model. don't dick around with a mass trigger one unless you're willing to dump $$ into an apex.
i recently went back to a G17 and am reminded how fantastic of a pistol these are. everybody is G19-crazy but i find the G17 a notch smoother and easier to shoot accurately. compared to the M&P 2.0 the G17 is substantially lighter and a bit harder to shoot accurately, although I suspect much of this is the weight difference. the M&P 2.0 has like near zero recoil. it's freakish. overall I prefer the G17 but not by much. the 2.0 has some big advantages (easier to shoot, great sights, nice machining, stipped grip, perfect ejection patterns). aside from the increased complexity, the M&P 2.0 is a step forward from the original design. it's improved without question. on the contrary I see the glock gen 5 as a step backwards....so if I had a choice between an M&P 2.0 or a glock gen 5 (i never thought i would say this) I would take the 2.0 without question.
the canik TP9SF is also a gem. it's pretty hard to justify buying an M&P 2.0 to then drop another $120 on a apex kit when one can get a phenomenal trigger on the canik for under $350. the M&P 10 rd mags still blow. they're way too tight and basically fit 9 rds at best. to accomodate 10 rds they require a coil to be removed and the internal side of the follower to be dremeled down. it's horseshit that S&W hasn't fixed their mags. on the other hand the canik 10rd mags fit 10 rds no problem and easily seat on a closed slide the way mags are supposed to work. i've never had a malfunction w my canik. it is a keeper. i feel like most threads about polymer pistols end up with a post from mikelawtown and I about how much we dig our Canik TP9's.
