Congrats on the Browing Gold 3 1/2. I have had mine for 4 years now and couldn't be happier. As far as chokes are concerned, the Dealer informed me theonly way that I could improve my Browning would be to get a Briley choke. I bought the Modified Invector Plus Ported wich actually shoots full with steel shot. You won'tfind a better
choke.
