I have 2 blued new model Blackhawks, both in .357, both with 4 5/8" barrel. One is from 1976, the other is current production, NIB. I noticed that the 1976 model felt a bit lighter. In checking the ejector shrouds, the current newer model is highly magnetic (as much as the barrel), and the 76 model does not react to the magnet whatsoever. I thought regular Blackhawk models in .357 were supposed to have ally, or aluminum ejector shrouds??
