I've owned a handful of Pythons. Always believed they were the best of the best. And, I was always dissapointed. They look stunning. The craftsmanship is flawless and the accuracy is as good as it gets. I just never warmed up to the DA trigger and never could shoot one to its full potential. I still have one, just because I think every revolver guy should have at least one Python, but, when it came down to a carry gun or just plain old shooting, I never found an equal to the Smith M-27. So much so that I own 5 of them, two of them being RM's (for the sake of argument, I consider them M-27's) and one M-28.
Truth be told, I would rather own a Model 28 Highway Patrolman than a Python. I'm not talking about resale value, collector value or anything other than just a great shooting revolver.
Gotta remember too, the M-27 is the direct line decendant of the original Smith and Wesson .357 Magnum, the first real Magnum ever made...
If you like the looks of the Python...if the trigger works for you, I doubt you will be dissapointed. Its a fine gun in its own right.
If you are in the DFW area, holler at me. You supply the ammo, I'll supply the guns and you can figure it out for yourself.
