If anything, the technology developed by Ruger is MORE refined than the age-old manufacture using forgings.
Castings might not have the ultimate edge in test to destruction, but the guns, any of them, are over-built, no matter the manufacturer.
The amount of difference in casting vs. forging isn't nearly as much as alluded to, either.
Besides, too many of those purportedly "more refined" guns now come chock full of MIM parts, polymer parts, and two-piece barrels, with a "gasp" cast outer cover.
Ruger has developed the SR series, which is much lighter in mass. Funny thing, though, they are still using cast slides. One would think that they would have the failures promised by the forged bunch, wouldn't you?
