According to SCSW, dcopper is correct on the Mod 637 "dash" variations. The corresponding dates were: 1989 (637), 1996 (-1), and 2002 (-2). The 3rd Edition SCSW, published in 2006, doesn't list a 637-3, and I don't know if one has been introduced since that time.
I carried a 637 for a while but eventually sold it and bought a 642 with the CT grips, which was (and is) a better design for my intended use of the gun.
