If you've ever overlaid a Colt DS on a j-frame Smith, you'll see that they're just about the same size. I know the DS came first, but the best comparison I can come up with is that it's as if Colt took a Chief Spl & heated it up until they could jam in a 6-shot cylinder. I don't know why S&W can't do the same thing and come up with a "fat j-frame", sort of halfway between a j & a k. Another new one could be a snubby k-frame but with a 5 shot 44 or 45 cylinder. Make them old-school-- no titanium scandium or unobtanium, no slab-sided barrels, no zombie sights.
