I've owned a bunch of 686 snubs, mostly 3", because I like their looks and how well they handle recoil. But they're a little fat for hours of comfortable carry.
The Miculek grips were too thin for me, and the upper ridge on them always whacked my hand. I'd much prefer Ahrends round butts, if I didn't have a couple of pairs of customized laminates I bought off a guy who made them from some conventional grips (maybe Badgers).
