I just purchased a 357 blackhawk with a brass grip frame. Smith & Wesson Model 27-2 Revolver serial #S330961, 357 Magnum, 8 3/8' pinned barrel with an excellent bore.
Not only did Ruger re- manufacture the original 357 flat top Magnum Innd 44 flat top Magnum commemerating their 50th anniversary but they added some nice touches like the gold inscriptions. For my 357 20' Rossi lever action carbine the 358-477 bullets won't even group at this point.
