If you could own only one revolver, but you didn't need it to be a j-frame for concealment, what would you buy?
I would like it to be practical enough for self-defense, and it should be carryable appendix in a pinch, but I wouldn't need to pocket carry it, per se.
Under those guidelines, it would be a short barrled 66. Toss the appendix part out and I'd go with a 4" 686.
