The Browning Golds may very well have one of, or are the worst receiver/forearm junction in semi auto's. What I have done on some Golds is take the forearm off. There is a low spot on the bottom of the receiver. I lay a big bead of black silicone that's higher than the inside of the forearm. Let it dry and shave it down with a razor blade if needed. You want it just ever so slightly higher than the inside of the forearm. It takes the play right out and you can't even see it with the forearm on.
