DW are exellent guns. The shortes double action trigger in ill revolvers.
The action is not as clean as in Smith, but close.
They have no removable side plate, so the frame is stronger.
One thing you should know is that their frameas are not forged, they are investment casted (a la ruger).
The lockwork is very dfferent from any other revolver.
They are VERY acurate. They are also expensive, or at least new ones are.
I have an old DW 44mag and I love it.
Too large for carry though.
