Let me first say that I don't feel "calling the shot" is exactly rocket science. And if the 6" gun's longer sight radius is truely that much more precision, calling the shot would actually be less of a factor with the 6" gun than it would be with a 5" gun. I have seen many people that can shoot a 4" gun as accurately as a 5" gun at the drop of a hat. Point being that you need to call your shot to be accurate at any length barrel. I doubt that the sight radius is the most valuable reasoning behind the advantage of a 6" gun. And if that is the bread and butter difference, then there is little advantage in my opinion. I would like to have the opportunity to really check them out side by side. But let me say that as for now, I think it is snake oil, fad, gimic or passing fancy. But have not had the opportunity to prove otherwise. I did shoot the one Darryl had last year (which is your's now?) and found it to be a bit "snappier" than my Edge. The sights didn't settle back to point of aim as nicely as the Edge, and felt recoil was not significantly lighter either. But that was only in the course of one 20 round magazine. I am sure with at gun custom setup it would be more to my liking- but would it TRUELY be BETTER than a 5"? I am skeptical...
