Let me start by saying i own revolvers, carry revolvers and love shooting them. In fact i just bought a Korth Mongoose 4" which constituted a significant investment in a revolver. So when i say this its not because i don't like them
Their time has come and gone from Smith and Wesson's perspective. The Smith goal is to stamp out as much plastic as they can for the least amount of money while charging the consumer what the most the market will allow. Its that simple. The new age shooter (sadly) doesn't even consider a revolver when buying a gun. I have spoken to many many handgun enthusiasts, who have never owned or fired one and they have no intention to do so. For better or worse thats the market for which Smith is producing handguns.
I cannot see any reason Smith would alter their entire production philosophy to sell (maybe) a couple thousand revolvers.
I wish/hope i am wrong because the pre canted barrel era Smith revolvers i have owned were awesome guns. I just cannot see us getting back to that era ever again.
Even producing a standard factory model 629 2" at this juncture would seem to me to be a major departure from their present day business plan.
Just my opinion FWIW.
