I had a 20 gauge many years ago. A Browning version. Also had numerous opportunities to look at the Winchester version. I also owned the Browning version of the Model 42.
With all that said I never shot them that much but they were put together very nicely.
Now I will say, that Michael McIntosh wrote in his Best Guns book that even though the Browning Model 12 was not a double he still considered it a "Best" gun. Something to consider coming from someone who knows his way around double guns
