No, I've found that as long as they're not Cor-Bon or Buffbore 38+P, shooting +P in a 17oz snub isn't bad.
S&W's classic steel 36 with a 2" barrel was only a 19oz gun.
The problems seems to start below 15oz (some Taurus TI snubs), at least for most adult males - pain, lack of control and bullet yanking. By the time you hit 12oz or esp. 10.5oz (both S&W) you've gone WAY past the point of sanity.
In my opinion.
Note that I'm talking exclusively about 38+P here. In 357, I think the "sanity cut-off point" is about 20/21oz and that's only because newer medium-powered 357 loads are available that work well in snubs:
* Speer's 135gr 357Mag "short barrel".
* Remington Golden Saber 125gr.
* Cor-Bon's 125gr DPX (loaded milder than any other Cor-Bon defense ammo that I know of, for the caliber).
Ruger's SP101 is 27oz and if I recall right, most of the K-Frame 357s were in the 24 - 27oz range depending on options.
