Need help selecting my next revolver.

[Chukar60]

J frame 60-10 3". Easy to carry, shoots 357, and very accurate. At least the one I had was.
If you are hooked on the K/L platform, I have to go with what several others have suggested. 686 in your preferred barrel length.

As others have said, 686 is a great revolver. I own a 4" plus and love it.
Now...don't be afraid to pick up a N frame. You didn't say you were going to carry it, right? Yes, they're bigger and heavier but sure don't feel that way to me in the hand. I just bought a 627 pro and what a wonderful shooter. 8 rounds of stout 357 mag puts a hell of a grin on your face!
Also, you like revolvers, you hand load and pretty much got .357 covered. Why not a big bore? 44 mag isn't all that much more to handload and the grin factor is up another level.
