I have a series 80 Officers' Model in stainless steel. It is carried in a Bianchi 16HL shoulder rig, and is a pretty tight, but secure fit. Near the muzzle end there are scuff marks on the slide, which I am sure are from insertion and removal into the holster. These are not scratches, but look more like polish lines that appear when a piece of metal is polished in one direction, and then a final pass is made in a perpendicular direction. I am sure they can be polished out, but don't know what would be the proper way to do this. It seems to me that a cotton buffing wheel charged with the proper grit polishing compound would do the trick. However, since the slide had the matte finish and not the high polish bright finish, I want to bring the matte finish back, and not polish the area to the bright finish. I believe it is a matter of using the proper grit size. Does anyone have any suggestions on the proper way and proper grit size to use?
