I own several S&W revolvers. I have been looking at S&W performance shop model 627,627 v-comp and the trr8. All of them are 8 shot .357 mag. Im a big .357 guy and an 8 shot revolver! Well you know. They are pricey. But i have the money and i want a really nice pistol. And later would like to customize it further. Does anyone own one of these or have experience with one. I dont know to go with all metal(stainless) or the trr8 which is an alloy(scandium). Dont know if the scandium alloy would hold up? And which of them has the better barrel. S&Ws website has hardly any info other than the specs.
