I just gotta get this off my chest...
None of the performance center barrels do anything for me. I don't know how they supposedly enhance the performance. To me they look gimmicky, like someone thought slab siding the barrels would entice auto owners to buy a revolver. And the barrels with the extractor rod shows through the shroud on both sides reminds me of an old cheap High Standard revolver. And since I'm on my soapbox, I might as well mention I do not like unfluted cylinders either.
I guess if I want a traditional all weather Model 27, my best bet is to find one with an imperfect finish, then send it out to be hard chromed. I just want a stainless version of an original style 27.
And that goes for other calibers as well. Have passed up several because of non-traditional features.
Perhaps S&W could do some custom orders, being able to provide a fluted cylinder or traditional barrel upon special order, for their performance center models.
