There are actually 7 pieces in the M&P trigger group, 2 parts of the trigger, the pin that holds the 2 parts together, the pin that they ride on, the return spring, the pin that attaches the spring to the trigger, and the bar. If you had a Pro, you may have experienced "sear float" but the fix for that was available within a couple of weeks of the first reported case - I've run splits under .2 and haven't seen any sign of it even though I've run the trigger as low as 2.5 lbs. As far as loose feeling goes, wait until you've had a 92 break a locking block, that's loose. As far as Glock goes, they haven't had a totally problem free existence, my first one broke it's return spring, I've held one that Kaboomed and seen 2 others go, and the Gen3.5 40 cal guns had issues with a flashlight mounted. The current Gen4 guns have had issues with recoil spring assemblies and extractors. This isn't to knock any one gun, it's to knock ALL of them - every single gun made has had issues, way back when, "good, German made" Sigs split the frame rails at the back of the receiver. There's no perfect device that was made by human hands. Smith and Wesson has a lifetime warranty on their guns and 2 warranty centres in Canada. Either gun can be repaired and maintained at home, with little or no tools.
this is it. I've owned four Glocks (17, 34, 23, 19) over the past 21 years and have owned an M&P40 for the past two. No question--Glocks are very good, reliable pistols but the M&P series improves on many of the Glock shortcomings to make what I think is a better pistol. I posted this comparison a couple of years ago when I first got my M&P40...and I feel even more strongly than the M&P is a better pistol.
