S&W barrels would have to be set back the distance of one full turn ............about .028" minus just enough for fitting an appropriate crush. Removing .005" from the shoulder would mean the entire barrel would not be aligned properly.

Whoops, typo. >.028 is correct. On the newer guns, .026-.027 is better to allow for a crush fit when reinstalling, since they have no pin. The last one I did needed the barrel/cylinder gap reduced .005 to be back to .006 after the end shake had been removed and I guess that stuck in my head. (B/C was ~.011, should optimally be .003-.006, but .009 is still acceptable, so they say.)

The Taurus isn’t an “elderly” S&W design. It is similar but distinctly different, especially the coil mainspring. IMO, the leaf mainspring of the S&W is the key to its smooth, even DA trigger (at least the potential for.)
Check the sticky at the top of the forum by Outpost75 titled “revolver inspection 101”. It’s got everything you need to know (and more) about inspecting used DA revolvers.
