I like my old six shot L-frame,. but my performance center 5" N-frame is not any heavier and holds eight shots. Any S&W that fits my hand and has enough weight for the load used has been a joy to me.
The 686 Plus does it for me.
The 5 and 7 shot S&W cylinders have the stop notch between the chambers, not at the chambers. A little stronger I think. Might be over thinking it though.
But the full lugged barrel balances better for me in 3 and 4" class.
But I do like my N frames.
