My opinion is simply that spending thousands on a Python is so someone can feel as if he has a special gun, one that is "better" then the S&W or the Ruger, and feel good about "seeing" how beautiful the emperors new cloths are.
As for me, I know the emperor is actually naked.
The educated term for the phenomenon is call Cognitive Dissonance, the the wisdom of how it's explained in the child story of the Emperors New Cloths should not be dismissed or bypassed.
Pythons are a top level guns and the quality is as good as any, and better then some, but to think it is 3X better then a S&W is not realistic and as a gunsmith, I know what the fitting and tolerances are from both brands.
Bottom line?
If the Ruger GP100 is the standard for strength and is as accurate as any other DA 357,(and yes,,,,it is) and the S&W M27 is the standard of a historical 357 (the first 357s ever made were basically M27s even though they were not named that way in 1935) we have 2 guns that are in competition to establish what we believe a gun should be. Beauty is in the eye of the beholder, so that is not something that can be judged on a basis of hard evidence.
So we have the categories of
#1 Quality of fitting inside and out,
#2 accuracy.
#3 reliability of function in a set number of round fired. Let's say 50,000.
And #4 value of the above 3 categories viewed against the cost of the gun.
When judged this way, the Python does not stack up to be 3 times the gun of a S&W or Ruger.
Now, money is worth that the owner of the money values it at, just like all things, so if someone wants to spend $3000 (or $200,000 or any amount they want) on a gun that does nothing better then a $800 or $1200 gun, that 100% OK. It's his money!
But the problem comes when he wants to sell it for $3000 --- and at that point someone else must agree that gun is worth 3X or 4X what another gun costs that is every bit as good.
That's when the conversation starts to bend toward how beautiful the emperors cloths are.
