Just an FYI, the 686 is a L frame. So most things you look at for the 686 will not work with your 66 (K frame).
2.5" K Frames have something of a cult following. They are much less common than the 4" & even 6" versions in my experience. Very nice piece.
The barrel is pinned and the cylinder is recessed. That is a very desirable S&W pistol as they definitely do not make them like that anymore.
You can get a letter from the S&W Historical Foundation (for $75 the last I heard) for provenance if you’re interested. (I got one for my service revolver several years ago.)
My retired Australian Police S&W Model 10-5 (3” bbl) seems to be the perfect midsized CCW revolver.
