While "never say never" is a good philosophy to keep in mind with S&W corporate thinking ...
I'd never expect them to get back into the TDA metal pistol market again. The 1911 market is still profitable, but the other metal pistols can't compete with the proliferation of excellent plastic service-type pistols (and it would rob machine and tech time from 1911 production).
Now, if they would ever get back into it, and my state repealed that Roster (micro-stamping is the big restriction problem looming over any new design handguns
) ...
I'd wish for them to make a model they never got around to making, which is a 3916. That model number was never used, but if it were, it would mean a 3913 slide/barrel (made to TSW specs) on top of a stainless steel frame.
Heavier than an aluminum-framed 3913? Yep. But the short single stack wouldn't be very heavy, overall, and both the recoil management and the long term durability of an all-steel compact would be worth it.
Never expect it happen.
Pleasant daydream, though.
