Hey there,
Yes, the M3 can do it all.
I owned a M3 years ago but sold it after a short while. Nothing was wrong with it, I just thought it was too much of a compromise gun. It did many things ok, but for me, none very well.
As you said, it is heavier and my idea of a house gun is a light, short-barreled pump. And now my idea of a duck gun is a SBEII.
