Less recoil and far better accuracy (in my book) with the .357 SIG over the snorty .40s.
It seems that Most LE that have went to the .357 have tried the Forty in the past- and have
stuck with the .357 SIG- and are not changing anytime soon.
While the Forty is a good stopper, the .357 SIG seems to be a notch above.
A concealed citizen might have different needs than a state trooper, but the bottom result is that
you get dynamic stopping power with most loads on the market.
One famous writer and LEO trainer can carry any gun on the planet, and you see him mention that
the M&P357 is on his side (for the most part) these days.
That speaks well of the cartridge if he is devoting time to it, and he's not alone.
Which ever you can shoot more proficiently while you are moving to you long guns..... Pistols are not know for their stopping power, they are known to be light weight, easy to carry and conceal.
Seriously there is not a huge difference between any of the service pistol calibers using modern day ammunition.

The South Bend, Indiana police issue the 135-grain Cor-Bon .40 at 1,300 fps. Ballistics are roughly comparable to the typical .357 Sig police load, a 125-grain bullet at 1,350 fps. At the other end of the scale, you can stoke your .40 to a .38 Special hot-load level. The 165-grain subsonic at 1,000 is little different from the Cor-Bon .38 P load spitting a 158-grain lead hollowpoint at the same velocity
I think proficiency and shot placement are both a given. If you can't control your firearm or accurately place shots, find an alternative weapon. Speaking of alternative weapons, that's what a handgun is. It's a sidearm in case your primary weapon fails, runs out of ammo or is unavailable. A shotgun is pretty hard to beat for home defense since the pellets don't typically over penetrate and it's 90%+ one shot stop history with most departments/agencies. Plus unlike the majority of internet/media hype the racking of a shell normally has a psychological effect.
Between the .40 and .357, I'll take the .357. While the ballistics seem pretty close there's just not enough real life data to back up the 40. since it's so new. On the other hand the .357 has a pretty solid field history. My sidearms of choice when going into harms way has always been the .45 acp. I know from experience the type of devastating affects the .45 acp can deliver even if placement is not spot on. Simply put I prefer a larger caliber, heavy projectile. Chances are you and/or your target will be moving in a firefight so threading a needle with rounds while someone is firing at you is highly unlikely.
Just my $.02

Both are ok but IMO 357 hands down if your looking for a proven round that has higher chance of a first round stop.
I not bashing the .40 just not for me.
I have both and can't say a bad thing about either. I just happen to prefer the Sig's recoil.
Cost isn't an issue for me and it's definitely not because I'm loaded. It's because there isn't much of a difference. Especially with target loads.
I've also never had a problem with availability. I can't recall a time where I've walked into somewhere and they didn't have .357sig ammo and a good bit of it.

I don't have either, but I'd go with the .40 due to price, availability, etc. = more training = better skill with the weapon = greater potential for stopping.
Don't get caught up in which caliber has "the edge." There are better things to do with your gray matter.
Good luck (but practice often!).
