Both the model 39 and 59 were offered in nickel.
The model 41 and 52 were left out of the first gens.
The model 845, 945 and 952 were left out of the second gens.
I'm sure there are others.

Is this the much longer list you must have seen?
It is on "Smith and Wesson Forum", the S&W website with the blue background.
This overwhelmed me when first found, merely by chance.
As I and others mentioned earlier there are a number of such charts floating around. Most, more complete than the lucky Gunner chart and more accurate.
There is more complete info in the Standard Catalog.
The 41 and 46 are not any “Gen”, they don’t follow the S&W design for center fire semiauto pistols.
The 845, 945 and 952 are absolutely not 2nd Gens. These are hand fitted Performance Center Limited pistols. The 952 most closely aligns with the 1st Gen, but isn’t one. The 845 most closely aligns itself with a 3rd Gen but isn’t one. And the 945, like the 41/46 isn’t any “Gen.” Nor are the 1911 pistols or the Sigma guns or the P99 series or the M&P.
S&W thought their number system made sense and it might have if they hadn’t sabotaged it all by themselves time after time after time again and again.
