Max, why would you ask Ted if there are going to be other problems down the road when I clearly implied (maybe more than implied) that the movement of the loose forend lug can result in kinked lower ribs? Regardless of Ted's negative general comments about Model 21 rib and lug reliability, he gave good advice about going to a pro. Yes, is the answer, more damage may be down the road, not the least of which is water intrusion past a rib separation. That results in rust that you can't see or get rid of. Blackdog mentions David Yale as someone who may be fixing these problems for less money than some others charge. Some guys charge up to two grand to resolder ribs and lugs on Model 21s. I, personally, would rather pay a bit less. Maybe Blackdog will tell us how much ex Maryland gunsmith, Mr. Yale, charges for this service.
