I have a 3", which has a full length extractor. Other than that, and an extra 1/2" barrel, it's the same revolver.
I do like it. It's compact, easily concealable and accurate enough at 10 yards. The weight is enough to cushion even the hottest .357 loads. Mine is wearing a pair of Ahrends boot grips, which disappear under light cover.
You won't be disappointed, except it's not well suited for plinking and target shooting due to the short sight radius. A 4" is much better balanced, and a lot easier to carry in the woods than the 6" barrel. Some states require a barrel longer than 4" for hunting.
The 686 is the right size for most of us - a K frame grip with a somewhat larger frame and cylinder. The 7 round cylinder is actually stronger than the 6, because the notch falls between the chambers.
