There have been reports that model stamped (post-1957) S & W revolvers were stronger than pre-model guns, which is why the factory used to state any steel model stamped K frame .38 Special was OK for the dreaded + P ammunition. Whether this was due to different heat treating, steel or other manufacturing processes is unclear. However, pre-war K frame .38s were advertised as safe with .38/44 loads (158 gr at 1100 fps). Not much clarity on this subject to me.

Historically, model 1917 Armys had then state-of-the-art heat treatment.
