After doing some work on a forend I think I've solved or will solve a very bad forend to frame fit. It lines up fairly well now. However when the forend is mounted to the barrel you can grab a hold of the forend and with moderate pressure slightly twist the forend. The movement is not a lot. Interestingly enough there is no movement when the breech is open, only when closed. I guess you could say it's free floated ever so slightly at the frame. There is no gap at the frame/spacer at all, just fits loose enough to allow some slight movement. See any problems with this? I suppose it could help accuracy as there is no hard contact at the frame.
