"Tool kit" comes to mind. There has been discussed a series of fixes for off-face. It should be fairly clear that they range in permanence from a few shots to a new life on the gun. They range in cost from a few cents and a few minutes of low skilled work to several hundred dollars and highly skilled work. Seems to me there is room for all the "tools." One only needs to match the "tool" to the gun, shooting conditions, intentions, and wallet.
Rocketman nicely summed up how many of us see this. Yesterday the cheapest, most fleeting "repair" filled the bill nicely. It may do so again, or, I may move to a temporary soft metal shim before shooting that gun again. Will see how this evolves.
Hopefully, this gun will go hunting at least a few times next season -- it has lots of plusses for me. Previous owner(s) in Sweden used it lots and kept it well repaired (other than off face condition). My last bag of ducks and geese fell to a newer model of much the same gun, as all others have this year. Maybe next year, awaiting shooting light, I will hear hunting stories in a Swedish dialect I understand..................
