Browning did drop the Satin Hunter but brought it back in 2006.
IMH0 3 1/2" shells in a 12 ga. borders on insanity anyway no matter in what configuration. If you feel the need for a 3 1/2 " 12 one would be better served with a 10ga.
They come with 28" barrels ad tip the scale at around 8 1/2 lbs. Now it you wanted to shoot 2 3/4 or 3 and use it for waterfowl and turkey it would be a good choice. The longer chamber would only add to softening the recoil with these loads a bit along with the back bored barrels. So many people think they have a 50 yd. gun but for 99% of the hunters this is only a fantasy.
