Yessir, I have 4 J-frame snubs, though they are all older.
The Taurus seems to be the same size in all but one respect. It has a shrouded extractor rod - kind of an underlugged barrel. But then so do some of the newer J-frames.
Otherwise it seems to be pretty much the same size in all respects. It fits the majority of my leather J-framed holsters. If I were at home (where the J-frames are) I could post a comparison photo.
Since I'm not the best I can do is show you this online comparison between a M60 and a Taurus 605 - which is the same frame and barrel size as the 627.

FWIW, I think the Charter Arms may be slightly smaller than the J-frames. At least they always looked like it to me. I always thought the Charter seemed more like an I-frame in size. Maybe just my perception. The only one I have to compare is my old 44spl Bulldog and I think it is built on a slightly larger frame than the 32 Undercover.
