That's pretty much how I see it too.
Now, I may be wrong, but I have heard numerous times that the Python was originally conceived as a large frame .38spl target gun. As such it is very accurate but supposedly somewhat deilcate for heavy .357mag use. It's single action trigger is sweet no doubt, however, it's double action trigger tends to "stack" due to the spring type, making it quite heavy toward the end. It is said that a steady diet of full power .357mag loads will eventually give you timing issues(I haven't experienced that with mine...yet). Then good luck finding someone ot put it right. Pythons are very expensive. The company that made them has nothing to do with double action revolvers anymore. Python spare parts are hard to get and costly. Aftermarket accesories are virtually non existent. Gunsmiths experienced in Colt repair are even more rare. If the legendary finish on your Python is damaged, your resale value tanks. So using and carrying it everyday will probably ruin any plans for profit resale.
So what you get is a very expensive, very accurate, delicate, vintage revolver that has a quirky double action trigger, that has to be handled like a princess lest it's resale value be gone.
All in all I feel that the price, lack of service, and general characteristics of the Python make it a very nice specialty bullseye gun, or a collectors piece. For work or everyday shooting I would hang with S&W. It's not nearly as expensive as a comparable condition Python. It's far easier to get spare parts, aftermarket items and service for the Smith. The 27 is just a beefier gun that will handle trigger time better with less headache and worries.
