By "grip" I assume you mean the wrist.
Check out the wrist on a H&H. It's truly remarkable. It has an eccentric cross-section that fits the hand very well - I think it is one of the reasons these guns handle so well.
I have a Beretta Silverhawk English stock DT SxS that I love dearly but mostly because my wife gave it to me. There is nothing wrong with the gun but the wrist feels very chunky now that I've graduated a bit.
I cannot comment on the RBL but I do understand the issue with the feel of the grip, or the wrist.
