I have a Sp101 3" in 327. It sports some Secret Service Grips from Eagle. I rather like them, but I've heard several problems with Eagle in the past. Mine don't fit the tightest, but it was easy enough to correct on my own.
As for holsters, what are you looking for? IWB, Tuckable, OWB?
I use a Simply Rugged pancake for OWB, and with some inside out straps for IWB. I also have a Desantis (I don't recall the model) which works nicely for OWB if I want a retention strap. I have a High-Noon tuckable holster from an old Taurus 357 that fits just fine that I've used now and again, but by and large I don't care for it.
