Every time this discussion arises about a 2" 12 ga. vs a 20 ga., I find it puzzling that no one mentions the actual physical dimensions of each in comparison. The 20 ga. is a much more trim and narrow-framed gun than any 12 ga. gun, regardless of chamber length or weight. Sure, there are a few odd heavyweight 20's out there, but typically, a light 20 will be a much more sleek and small-in-the-hands gun than a 2" 12 ga. Just saying.
