I've got both a 586 L-Comp and a 3" 686+. Having both, to me, was the right choice to make (again, for me).
The black finish does have some wear, but not much now that my gun is ~8.5 years old. It seems the wear is from me using speedloaders. Note, I've got 8700+ rounds through this gun at this time.
Although I've had the 586 L-Comp checked by a gunsmith, I've found my gun, or I, shoot this gun a bit to the left. I've adjusted the rear sight to the right to compensate. I've not bothered to send the gun back to S&W for them to look at it in all these years.
The front night sight on this 586 was all but useless as its lamp was somewhat dim when new and recessed into the front sight blade. I've since replaced the front sight with one with a brass bead; personal preference.
My 686+ seems to shoot to point of aim with the rear sight visually centered. I've only got ~450 rounds through this gun in the year I've owned it.
I normally carry .38 Special. Having the option of shooting .357 is nice, but not required in my imagined threat scenarios where I can anticipate shooting a living body more than planning to shoot at a barricaded threat, such as in a vehicle or some type of medium "cover" whether 1 to 50 yards.
I suppose a K-frame would meet my needs just as well. I do also have a K-frame along with several J-frames for additional choices/variety.
Nobody else can make the decision for Post1's author. Good luck OP
