I suspect the modern steel J frames like the M60, M640, and M649 are stronger than the old K frames.
No flat spot for one thing.

I'm not so sure today's steel is stronger, although it may be more consistent.
I suspect the engineers at S&W considered the recoil and how many rounds of full power .357 Magnum ammunition the average shooter would put through it, and relied on the level of discomfort to limit the round count to ensure a suitable life span.
