Hi. I own a 38 yr old model 1100 in perfect shape. Except.the wood stock near rhe recoil pad is bowing out. like 1/8" high, by 1/4" square. I removed the recoil pad and the wood is not split. I am scared if i try to sand this down and refinish i may never get the stain color correct, or even mess up the carvings. If you have any advise, please respond. Thanks!
