The Model 80 was introduced in 1980, and remained in production until 2001, though it remains in production for South American-only sales today. The Model 80 has fixed sights, small hardwood grips, and a heavy tapering barrel 3 or 4 inches long. The ejector rod is unshrouded. The Model 80 was originally produced only with a blued finish, but later a nickel-plated model was added, as was a stainless steel version (sometimes called the Model 80SS) in 1993.
If it is nickel don't use Hoppes #9 or any ammonia-based solvents on nickel finishes - these have a copper layer underneath, and if the ammonia reaches the copper it will strip off the nickel. It breaks down the layers of copper plating under the nickel and causes the nickel to flake off.
Also if it is an 80 and not an 82 you should not shoot +P ammo through it. The Model 82 is similar to the Model 80 but unlike the Model 80, it has a full-length bull barrel with a prominent top rib and is heavier than the Model 80 because it was strengthened to handle +P ammunition.
