I looked at a S&W J frame at Gander Mountain yesterday. I was a bit confused. The Gander tag showed it as a 642. Many of their tags are marked incorrectly so I took a closer look. The first thing that caught my eye was that it was black like a 442. It also had a full shroud and a heavier, ported barrel. On the yoke it was indeed marked 642. It was about $250 higher than the standard 442 but the heavy barrel and porting answered that question. But I'm baffeled by the black finish on a 642. It was a .38 spl and not a .357. I just checked the S&W site and don't see it. Can anyone enlighten me?
