I have eight of them and shoot them quite a bit and I have never had one come off. I use my 32" for trap so I shoot it quite a bit at a time. The barrels get pretty hot but the ribs stay put. So, I wouldn't think it happens any more than on any other gun. Imagine all the rounds that have been put through over 2,000,000 Model 12s shooting trap over the years. Ever hear of problems with the ribs on them? Not me. Good luck.
