When I said it was blue, I didn't mean the bright anodized blue that I have seen on a titanium Taurus, but something closer to black. They had a S&W 642 there as well and it felt just a little lighter in my hand, but they were both significantly lighter than the two stainless models they had. I think the 850 in question was an aluminum frame with a steel cylinder and barrel, and not titanium.
The 642 had a cylinder that was long enough for 357Mag, but it was listed as a 38+P only. It looks like S&W just uses their 357 cylinders but reams them to 38 length. I wonder how the longer jump to the rifling affects the accuracy and chamber pressure. I actually liked the Taurus over the Smith for a couple of reasons, beside the shorter cylinder. For one thing I liked the trigger on that particular 850 better, it didn't drop off at the end like the Smith, and the ejector stroke was substantially longer on the 850, which should translate into few stuck brass.
A used P3AT was in the case as well. First time I held one; I do not have large hands, but man it did not feel good in my hand.
