I think the ruger security six is tops in the 357mag. Tied with the colt.
The s&w m27/m28 will hold up with normal factory 357 loads. But the Redhawk in 357 has to be the strongest.

As a kid in my 20's I was loading the 357 mag in stout loads. My SBH was over loaded in 44mag. I'm surprised I lived through those years. I'm older and wiser now. 45 years later.
