I think I may need to post some photos to get an assessment. All I know is that both of my Garbi's are showing minor signs. You couldn't fit a piece of paper between the locks and wood but the locks come out easily enough so I don't get the sense that they're binding. They're all copies of an H & H seven pin so I don't know if they're more prone surface area wise than anything else.
All I do know is that they shoot great and are expensive and I have no intentions of selling them. I'll take whatever steps I can to avoid having a real problem later.
