Can anyone offer advice regarding the barrel to my .38 Colt Cobra being frozen, or extremely difficult to open for loading - only under extreme pressure? I don't recall anything happening to it since I last used it, but that was about 20 years ago; since then it's been stored in a well-sealed lock box in good condition and other gun dealers have said it's not rusted and seems in great condition other than the barrel being stuck.
Thanks in advance.
