I think S&W just saw a crack they could slip into between those misinterpreting DD's and Ruger's positions
(IME I would not buy a new firearm from nearly any mfg in the past 4-5 years. They're all too involved with cranking them out while the 'gittin's good' and the chance of 'gittin' one made like the older ones are slimmer each year.)
It's ALL about the $$$
