the "6" doesn't always mean it's a stainless gun though, the 625s were 45ACP and 45LC gun model designations while the two were both in production if I remember correct(one or the other was a 625 for a short time).
There are a few that don't match up but in general a "6" denotes the gun is a stainless version of the model that is designated by the next two following numbers.
28s are 357 "highway patrolman" N-frame revolvers, I think all are matte blued.
27s are 357 N-framed revolvers, typically got the high polished blue.
29s are 44mags N-framed revolvers, various blued finishes.
I haven't followed the lineage of the N-frame revolvers much anymore since S&W made the STOOOOPID! decision to switch over to all stainless revolvers, yuckie! GIVE ME THE DEEP BLUE OF YESTERYEAR!
I just passed up a pretty nice 98+% condition Model 28 with a 6 inch barrel, for 430 dollars it wasn't quite what I wanted for it not being NIB or without box for that matter.
The N-frames I'm most interested in getting are a M29 blued 6 inch barreled 44mag, a 6inch barreled M27 357mag, and a 6 inch barreled M625 45LongColt.
