Little help if possible I am helping or trying to help my friend fix his wife 's STAR S.A .380 pistol it has broken firing pin I have to remove the rear site to remove firing pin but I can not get the site to move used site tool and hammer and brass punch and different lubricant 's if I heated it would it damage the blue I know these guns are real old and they don't make them anymore so I really don't want to damage it I had a hard time just finding the firing pin for it
