One warning about later made Browning O/U(s). If they've had a lot of rounds through them they will soon need rebolting. I've seen way too many shooting with a rubber band around the wrist and top lever to help prevent it from partially opening on the first shot. And, I've known of many more than that that have been sent back to Browning for rebolting.

Flame away. Just reporting what I've seen over the last 20 years.
