Sorry about being late for the discussion!
Personally, when I went with a 3" 357, I went with a 686+.
I had a few factors influence my selection. First, I have a 36-6 snub that I enjoy because of both the looks and the balance ... I wanted that in a 357. Second, I live in a state where a loaded magazine (all by it's lonesome) can get you 8 years in prison. For day trips in states where my non-resident permits are honored, I don't want to have to stop and empty all of my magazines, or risk forgetting to empty one, while a loaded speedloader won't raise an eye. Third, since some people equate the performance of a 357 Magnum to a 45, seven rounds of 357 gives me a comparable revolver to my 1911.
For grips, while I like the looks of the stock grips, I chose to install a pair of Hogue rubber Monogrips. When the heatwave breaks (maybe in February?), I plan on casting some Lyman 358156GCs and loading up a batch of Skeeter 357s for it.
