This discussion kinda reminds me of the soccer games everyone seems so fired up about...a lot of folks running in different directions, a whole lot of hollering, but not really much happening. I agree, the off-center ball detent is a little disconcerting and in a peculiar place (but obviously why when dimensions are closely examined) but, it works. Time and dollars spent will tell if this was a worthwhile venture on the part of S&W. I'll go out on a limb and say we will see other calibers in this configuration, possibly the .41 magnum or even the venerable .45 Colt.
