I was really suprised at how easily, for me at least, a few cylinders of 158 grain 357 Mags was outta my recently aquired 650 CIA? Now shootin' 125 grain mags is another story. I shot some out of my college buddy's S&W 642 and it was like slappin' my hand as hard as I could on concrete! No so with the 158 grainers. IWouldn't shoot a 50 rnd box, but it ain't enough to aquire the 125 gr. flinch. Great gun.
