I've only shot one and I didn't really like it. Odd, because I get along fine with the VE series Sigmas and a other guns most people abhor for their triggers. i think the thing that put me off about that particular gun was that the trigger had take-up, which I like; but then it turned to mush with a little gravel thrown in. It may have just been a substandard specimen... I've shot other M&P's and while I don't exactly like their triggers, none were as lousy as that 45.
The 45 also seemed to kick harder than it should. We were shooting a 1911 with the same loads so I'm sure that wasn't my imagination.
“Nine-tenths of tactics are certain, and taught in books: but the irrational tenth is like the kingfisher flashing across the pool, and that is the test of generals. It can only be ensured by instinct, sharpened by thought practicing the stroke so often that at the crisis it is as natural as a reflex.” ~ T. E. Lawrence
