Just looked at mine, Mike... the barrel shoulders that have the pin holes in them come off too.

They can be replaced.

Thought I remembered that.. mine has a bazillion rounds through it and is still tight.

I believe all 682's are like that and can be tightened either way or a combination of both.

Also, the hinge trunions can be punched out and replaced. That may be more necessary than the locking pins and holes.
