A long time ago, (sometime in the mid 70's) a Ruger factory rep told me that all Ruger's were proof tested with loads that run 30% above normal factory ammo. This was during a demonstration of "how tuff" the Blackhawk .357 and Super Blackhawk .44 magnums were made.
That makes sense if we're talking about their SA centerfire line in that period.
Starting in '73 Ruger took the unusual step of simplifying their product line such that ALL single action centerfires were built on a "44magnum class" frame - same as the SuperBlackHawk. And they built "lesser caliber guns" to the same strength grade, same heat-treat, etc.
So in 45LC you had an enormously strong gun that could take "44Magnum-class power". That led to the "Ruger ONLY!!!" 45LC+P loads.
In 357 you had "the gun that could not be killed", or close to it
. Only abnormally stupid handloading could blow one up.
And you could take that 357, ream the cylinder, swap barrels and convert it to 44Mag or beyond any time you wanted to.
Ruger now ships a couple of SAs built on a "mid-frame" or "357-class frame": the New Vaquero and 50th Anniversary 357 Blackhawk. These are REALLY nice guns and can take any factory 357 ammo, but the New Vaq in 45LC should be fed the same loads a Colt SAA 2nd/3rd gen can take, avoiding the "45+P" fodder.
What else...the GP100 DA is hell-for-stout. The SP101 holds the title of "world's strongest 5-shot snubby"...also the heaviest
but that's the tradeoff, ain't it?
Warning labels are migrating to the BOTTOMS of the barrels instead of the sides. Thank God.
There are no "bad" Ruger revolvers. The Alaskan in 454 and 480 are kinda silly
and the "Ruger480" caliber doesn't seem to have worked out - all new specimens are discontinued.
The lifetime repair policy ain't bad - and they don't even ask if you're the original owner. If it's an older gun and you obviously bunged it up, they'll fix it for cheap. If there's even a hint it was their fault, no matter how long ago, change that to "free".

Only caveat: while QC of late has been quite good, these are still mass-produced guns. I will not buy one "sight unseen" and I will always run "the checkout" (see stickied thread).
I'm a very satisfied owner of a New Vaquero in 357, now somewhat modified to my taste: SuperBlackHawk hammer dropped straight in and reduced hammer reach, spring kit, improved sights and a bit of psych warfare on the ejector rod head
. BUT the gun shot perfectly out of the box after being one of THREE at the dealer that all passed checkout perfectly. This one got picked for it's unusual all-smoky-gray "fake case color job".
