I'm pretty sure the 3 1/2" twenty was only developed to overcome a ballistic challenge in a slug that size, and birdshot has never been loaded in the hulls of that length. It is a wonderful deer gun, according to some things I have read.
Not everyone likes fat women, but, some do. God gave us both, and, we get to choose between 12 and 16, also. My 16s make sense, to me. The receiver on my 1957 Ithaca 16 is about the same as the one on my 1933 model 17 20 gauge.
Browning hasn't built anything I would spend my after tax dollars on in about fifty years.
Best,
