I have 686s in both the standard and the + versions. Some say the trigger in DA is better in the 7 shot models as compared to the 6 shot revolvers because the cylinder doesn't have to travel as far. My youngest son who shoots in DA all the time claims this is true. Me, I can't tell the difference. As for hunting/plinking, I see no advantage one way or the other either. If you missed your quarry 6 times already, odds are, you ain't gonna get 'em on the 7th. At the range, a box of 50 will leave you two rounds left with a six shooter and only 1 with the seven. In most gun stores I visit there is no price difference either. I always figured S&W would at some point phase out the 6 shot in favor of the 7, but I'd guess the purists won't allow them too.
