This has been an interesting thread. Good discussion.

"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.
