I personally would go with a 7.62x25 pistol or round before going with a .357 sig.
Show me a gun of quality construction and proven reliability that is chambered for it... When it comes to defensive use it is shot placement that trumps all. Calibre, bullet weight, bullet style etc etc are moot points.

It isn't terribly hard to find ammo for it. I don't think ammosupply.ca has ever
left me hanging. The price however, yes, it is high.
Defensive shooting is not target shooting, you shoot what you can see in hopes that even a peripheral hit will stop the action of your antagonist, therefore it is desirable to put as much power on the target as possible. A large ragged hole puts more blood on the floor than a small clean one, so to say that a bullet's frontal diameter, weight, impact velocity, and so on are moot points is not entirely accurate. That said, I do agree that in a life saving implement, reliability and robustness trump all other considerations.

I understand the concepts of defensive shooting. Control, and capacity are far more important than calibre, bullet design, make and model. The statistical average number of shots required to end a a threat is three, regardless of calibre. I will stick to more rounds in a more controllable platform over fewer rounds of a "more potent" calibre.

If standard service ammunition is observed, there is little difference in the amount of recoil from gun to gun, but there can be a significant difference in magazine capacity. If control trumped all other considerations, the most popular defensive pistol would be a .22, but that doesn't seem to be the case, certainly not among enthusiasts. Choosing a more destructive, deeper penetrating bullet has no effect on either the recoil or magazine capacity of the pistol you already use. The difference in performance though is real. Increased bullet performance could end the fight sooner, reducing the threat to yourself and others, and it will give you greater confidence, a point of some importance in a fight.
If the average statistical number of rounds to end a fight is three, an old statistic which may no longer be relevant, then why are we concerned with magazine capacity? Because, as is so often the case, statistics don't reflect real life, where wolves travel in packs; and large capacity magazines are therefore desirable. Any reduction to the weight, expanded frontal area, or impact velocity of the bullet, will proportionately diminish the effectiveness of the individual round, as well as the confidence of the shooter relying on it to save his life.
Since the Op is asking because he is considering an exchange kit for his P226, I seriously doubt that SigArms makes an exchange kit for the P226 chambered in 7.62x25.
