I've shot GS out a 2.75 66 and yes it's noticably less ferocious than American Eagle 158.Full house 125 or 158 grain .357? Agreed.
But have you spent much time behind modern defense .357 loads? Remington Golden Saber 125gr, Speer Gold Dot 135gr Short Barrel, and either mid-grain loaded from Critical Defense/Duty just to name a few. Powder's optimized for low flash and in my experience it's pretty effective compared to the old cannon blast days.
OTOH, once 357 is tamed to a "carry" load and especially in a 2", now it's in the category of a 9+P. A whole 'nuther universe of guns opens....
