Well that got me scrambling for my S&W reference book. If I were King I’d have S&W bring back the i frame (smaller than the j frame) as an Airweight but this time in 9mm or 9mm Federal, that would be the ultimate snubbie.
32 H&R....but I like your thinking!
The longer cylinders are wasted, simply because the 357 nuts in those guns. More oomph should be translated into heavier bullets.
