I started Collecting S&W revolvers about 8 years ago and I was in Love with the Model 27-2 and I owned every barrel length except 6.5 which are hard to fine in the 27-2 and easier in the pre 27-2 because more were made. I bought a 28-2 with 6 inch barrel as my range 357 and it was at least $250 cheaper then the 27-2 with 6 inch barrel. I owned both the nickel and blued version of the 27-2 in the 5 inch, 6 inch and 8 3/8 inch.
The past two years the 28-2 has grown in status and the prices have increased especially on the 4 inch with an S serial number but even with the N serial numbered 4 inch. The prices have gone up and now they have closed the cap in some cases to $100 -$150 of the cost of the 27-2.
The actual flagship of S&W revolvers is the Registered Magnum and that is probably the closest you can compare to the Colt Python.
