Nothing is perfect but I nave not ever seen a gun that was so positively reviewed by most everyone that handles and shoots this pistol. I am still looking for an article that seriously slams this gun on any front other than more availability of guns and magazines. The reported number of small issues with this gun must make a tiny fraction of delivered pistols because they very seldom appear in forums other than obvious defects that S&W has, or will, correct at their cost.
This is my first M&P pistol and I think S&W really thought this gun out. I bought it because I am an instructor and I thought it would make a great pistol for student shooters of all sizes. I have only about 400 rounds of assorted factory and handloads butI have not had a malfunction of any kind. If you are looking for a reasonably priced "all purpose gun ", I think the Shield should really get your attention.
