Yep. I detail-stripped my 5906 once for a good cleaning, and I was amazed at how many intricately machined little parts it had compared to a Glock or something, and how long it took to put it together. I would expect that a 3rd-gen Smith requires two or three times the man-hours to manufacture and assemble than a Glock does. They are very well designed and built, though.So would lots of people, but making them now would be prohibitive, I think.
I believe some of the last 3rd-gens made for general sale were Performance Center and TSW models. I wanted one of those badly for a while, but they were priced well out of my range. I believe that even my little 3913LS cost close to $600 back in the mid-1990s, which was a lot of money at the time.
