It's not the same S&W that caved to Clinton.
The M&P pistol line is excellent. I've been a Glock fan since 1995, but 5 years ago I wanted a more natural grip angle. The M&P matches my S&W revolvers. It's a natural choice.
And Glock still has not come out with a small, concealable slimline SA series, like the M&P Shield series.
That's why.
For what it is worth, Chuck Hawks does think too highly of S&W: http://www.chuckhawks.com/smith-wesson_dark.htm
