Found somthing very interesting at the local gun store yesterday---a new, ITB, "6" inch 686 in stainless with an unfluted cylinder---is this a model variation that's possible and is offered from the factory or should I be a little suspicious? First time I've ever seen an "L" frame with an unfluted cylinder---it looks great, crane to frame fit is very good, cylinder/barrel gap is good and the lock up is nice and tight etc ---has the lock, but that can be easily remedied---should I the snap this up ?
