Smith & Wesson are (or at least were) finely made, well tuned firearms built to last a lifetime.
"Were" is the operative word. Twenty or twenty-five years ago, Smiths were a better revolver, but if you purchased and used some of their current offerings it's a completely different story.
They now use MIM parts in the trigger action. I could not find a gunsmith that was willing to do anything with the actions but change springs. Meaning tuning the trigger like you used to be able to have done on a Smith is a thing of the past.
The Jerry Miculek 625 I purchased had to have the barrel crown redone AND the cylinder retimed from the factory. The trigger pull, after some work is 5.5 pounds SA and 7.5 pounds DA. The gun is allegedly one of their "elite" pistols that represents the best they make ....yeah...bad barrel crown and cylinder timing from the factory.
The S&W .460 trigger was so bad on DA it maxed out my trigger pull gage at 14+ pounds. After some work, it's a miserable 9.5 lbs DA and 7.5 lbs SA.
The Ruger Super Redhawk Alaskan that I purchased at the same time has a far better DA and SA action than the Smiths.
But, none of the triggers are nearly as good as the used S&W circa 1980 model 629 - that, from the factory, has a trigger that is 6.5 lbs DA and 5 lbs SA.
Don't conflate what Smiths "used to be" with the pedestrian pistols they turning out today.
From my latest experiences with both S&W and Ruger - the Ruger is functionally a better pistol.
