Xtreme, my EDC is a S&W M&P 40c.
Advantages of the shorter barrel, for me...well, I can conceal my 40fs just as easily, but the compact's a more comfortable carry for me due to the barrel, and grip as well. That said, I'm so used to shooting either one I can't tell much difference in accuracy anymore... Is that a bad thing?
And yeah, they are nice looking. Very comfortable grip, which is what drew me to M&P's in the first place. The fact that they are both accurate and reliable just makes me appreciate them that much more.
Shoot as many as you can get your hands on before you decide...
