Taurus Model 80

* * * * *
Notes: The Model 80 was introduced in 1980, and as far as is known, remained in production until 2001, though it may remain 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.

The Model 82 is a similar revolver made at the same time. Like the Model 80, it was a popular export to the US and Europe. Unlike the Model 80, it has a full-length bull barrel with a prominent top rib and is heavier than the Model 80. The same finishes were used on the Model 82, though the stainless steel version was offered only with a 4-inch barrel. Another variant, the Model 82B, is virtually identical, but is strengthened to handle +P ammunition. It was offered only with a 4-inch barrel and is again heavier than the standard Model 82.

As for you primary question I don't know if it is rated to handle +p ammo.
