Another note on S&W M&P autos:I am now looking at trading it for a glock because the XD is much more bulky. It is heavier and wider, thus more difficult to conceal.
I like the trigger pull on these better than the Glock. However, the actions on some new guns seem to be much smoother than others. Some folks with more experience with them than I have advise that they smooth out nicely after breakin. If you like them, you might want to try several examples and pick the one with the best pull out of the box.
