Where to begin? The 586 was S&W's response to the issues that arose with the K frame .357 magnums in the sixties and seventies. The K-frame magnums weren't meant to be used with a steady diet of magnum loads - even though there are many who state that they have used their Model 19's/65/13/66 without any trouble for years.
Our 357 mag. ammo adds more power than ever before to the 357 mag. This ammo is safe to shoot in ANY all steel 357 revolver—this includes J frames. This ammo is no harder on your gun than any other normal 357 ammo. Please don’t phone us and ask if this ammo is safe in your gun. It is, providing your gun is in safe condition for use with any normal 357 ammo.
We don’t recommend this ammo to be fired in super light alloy revolvers as bullets may jump crimp under recoil, but the ammo itself wont hurt these super light weight revolvers. These revolvers are simply so light that the recoil is severe enough to cause crimp jump.
The below velocities are offered so that you can see what guns/barrel lengths give what velocities with this new 357 mag. ammo. You’ll notice that new S&W revolvers with short barrels are often shooting faster than older S&W revolvers with longer barrels. The new S&W revolvers are very good and are made with equipment that makes them more consistent and faster than the S&W revolvers of yesteryear.
The Python was originally developed to be a .357 magnum. It evolved from the Colt "357" magnum which was Colt's first medium frame .357 magnum. The Officers Models were the .38 spl target revolvers (and had been for decades) and they were built on the same size frame as the Python. The Python never had any trouble with any of the .357 magnum loadings. Where a Python does have trouble is with fast double action shooting. The heavy cylinder pounds the small parts and cause it to lose it's timing. The old style Colt action was expensive to build due to the needed hand labor. The Trooper MkIII was Colt's answer to build an easier to produce action. The King Cobra was just the last in the line of evolution of the Trooper.What I can learn from research is that the Python was originally intended to be a 38 special target revolver. The changeover to the magnum was a last minute type of thing. Some say that the King Cobra was Colt's tacit admission that the Python wasn't designed for a steady diet of magnum loads becasue that model will handle the round. Incidentally the Python was introduced in the mid-fifties.

But if you think that you know how ammunition effects weapons more then a company who makes and tests high performance ammunition to be sure it's safe in firearms and won't destroy them or the user then believe what you want to believe.
Jeff,I've got an article by John Taffin from a few years ago in which he stated that the Python was originally developed as a 38 special target handgun, but when Colt realized what they had they changed and went to .357 magnum.
I am looking for a four inch carry revolver and am looking at either a S&W 586 .357 or a Colt Python .357. Pythons are bringing much higher prices and any views as to preference would be most appreciated.
