I have a serious "thing" for Smith & Wesson double action revolvers. Sadly, I find modern S&W revolvers to be cheap copies of S&W revolvers.
Therefore, I do not buy ANY S&W revolver without a pinned barrel. The one exemption to that is the very early L frame revolvers, either no dash or -2 only.
They are more expensive. At the risk of offending the current S&W corporation, quality always costs more.
The revolver you propose Wronghanded, is going to be found as either a K, L, or N frame revolver in .357 Magnum chambering in reasonably good condition. Truthfully, the N frame revolvers are monsters, but are monstrous for daily or constant carry. The L frames are just a bit large for my taste - although the grip frame is identical to the K frame. The K frames are the most 'useful' in my mind. The one weakness they have is after long exposure to high pressure loadings, the top strap can stretch and the cylinder develop excessive end play. The K-frames are also subject to cracking the forcing cones (rear part of barrel) when fired often with 125 grain, full power loads. S&W no longer makes barrels to fit the old (quality) revolvers and the old stock replacements are very hard to find.
One does still find old S&W M19-3s at gun shows and such. Usually at higher prices; they are in demand. I haven't seen a Model 19 or -1 for a very long time.
