Just picked up an early 989M2 (no serial number, 'FJ' code). From everything I can see it doesn't look like this one has ever been taken down. I want to give it a good cleaning and lube, replace the buffer, etc. before shooting it. I'm having a problem getting the barrel band off. I've never had this issue before but on this gun it looks like the wood just forward of the band on the lower stock has expanded slightly. It's like there is a very small area that is angled outward. I know it wasn't made this way, but this isn't like the stock warped from dampness/water either. The angle is completely uniform the whole way around the lower stock. Had anyone experienced this, and if so how did you deal with it. The first thing that came to mind was to carefully mask off the band and very carefully try to sand the area flat, but that's not going to look too swift and this gun has a really nice original stock that I didn't want to refinish if I can avoid it. Any suggestions?
