OB, I agree with you that the procedure (spray welding) is "commonly used" but some, no most, treat it as black magic. What is the truth and who uses it? In my opinion, sawing off the loop (correct term is "hook", my error) and dovetailing a new loop (again, correct term is "hook") surface is overkill but many talented gunsmiths insist on this method. What do they do when this fix wears out, do it again? I think the shim is the easiest and the most unobtrusive to the originality of the gun. The spray weld may be just as unobtrusive and about as easy. What do we think?
