Everyone who thinks the Python is the pinnacle of revolvers needs to shoot a N frame 357. Seems to be a lot of people who agree on Smith 357s. I know mine have all been great.
I've got both, and I'd tend to rate them about the same. I probably "like" the Python a little better, but only because I wanted one longer. I've owned three 27's, including a five screw "pre-27" but sold two of them in my great gun drawdown. If there is a practical difference, I can't tell it.
For God so loved the world, that He gave His only begotten Son, that whoever believes in Him should not perish, but have everlasting life.
John 3:16 (NKJV)
