All of mine were repaired with laser welding some more material to the worn surface. Modern tech solving century old problems. 10-15 minutes in the laser welder and a little bit of fitting then bobs your uncle.

I've seen actions tightened very well with steel shim stock attached with adhesive. Very clean repair and permanent unless you apply a torch to remove it.

Glue a shim in place. End of story.

My SC SBT has a shim; works very well. It's not even glued on; I just need to be mindful when I take the barrel off.

I think worst case scenario you’re more than likely $1500 high on your cost .

My maternal grandfathers 10 gauge W&C Scott crystal indicator gun has a shim around the hinge pin he put in it back in 1946 and it works just fine .

I have used two different gunsmiths that will use a laser welder to build up the hook then re fit it. One charges $450 the other $475. As long as the rest of the gun is good and you are happy with it, it seems worth it to me.
