If I have a modern +P rated (made in the past 40 years or so) .38 special revolver like a S&W model 15, I cannot see why it shouldn't be safe to use 38 special cartridges loaded to 357 mag pressures - just like a S&W model 19.
What's up with that?

Think about your last two paragraphs?
Are 38 special brass the same size as a 357?
So if you load a smaller size case or any container with the pressures of a larger brass or container what happens?
You can load a 38 special cartridge to around 10%
LESS than a max 357 Mag to make up for the difference in case size. Not saying you should.
