Got my first M&P 9c and like it a lot. It has the optional thumb safety which I chose.
But I wished the trigger position was back against the frame when the striker is not cocked, i.e. the Glock26 , which I like very, very very much. I often have my Glocks with magazines in, but no round chambered as an added safety feature, which is instantly visual, even from a distance.
No, I do not intend to start a pro/con argument over whether a loaded chamber is the way to go.
