I owned a 47E, hunted with it for about 3 years and sold it for an amount in excess of the purchase price. They are very stout guns. My example was new and the action was very tight. It seemed to me that the action would loosen up with more use, but I sold it before I was able to verify this theory. In the field, I always felt it was a smidge heavy. Perhaps it was merely my example. I have since migrated to English guns, but Krieghoff and Merkel were my first doublegun "loves".
Mine had 28" barrels and I found the weight to be nicely forward of the hinge pin due to the substantial tubes. I cannot speak to the 30's but I was satisfied with the 28's in the balance department as a game gun.
