When looking at power numbers for the .357sig, I've only found one factory load [so far] that significantly improves on the .40S&W or the 9mm+P loads: Sellier & Belliot .357sig 140gr at a claimed 1352fps and 563 ft/lbs of muzzle energy.
This is clearly an equal to most of the factory .357 Mag loads I've been looking at in the 148gr or 158gr weights. S&B does make a 158gr .357Mag with 683 ft/lbs of muzzle energy claimed, but most others seem in the 500s.
I forget who, but the boutique shops make some in the 700s or low 800s for .357mag.
I agree: .357sig vs .357Mag is a comparison that has to have it's role defined before you can argue which is better.
For backpacking and potential 4-legged critters attacking, I'd prefer a HOT .357mag out of my Ruger GP100. I mean, HOT!
For home defense I'd be afraid that would overpenetrate walls/assailants and harm my family. For home defense/carry and 2-legged threats, I'd like the extra capacity of the .357sig to the .357mag.
