Any advantage of the .357SIG over the .40S&W ?

[Alan Fud]

I own several .40's and have been giving serious thought to adding a .357SIG to my collection (it's the only serious caliber auto round that I presently don't own). However, with funds being tight, I really need to ask, is there any advantage to the .357SIG that is not found in the .40S&W?

Well if you have the right Sig or XD you can do a barrel and mag coversion from 40 to .357Sig.

It shoots a bit flatter, and offers some theoretical feed reliability advantages due to the bottleneck shape.

I have a pistol range in my back yard with steel targets. If you could see how fast the targets were destroyed when I switched from 40 to 357 you would know the 357 has a LOT more energy.

Since it's slightly smaller, and a bit faster, it has better penetration. I think it may be a good police round, since they have to sometimes shoot someone through glass, car door, etc.

I think for people who will end up defending themselves from someone that is standing in front of (or rushing towards) them, bigger holes bleed better.

No advantage.
I just bought mine when they first came out to tick-off the .40 people.

No real advantage at all. Some will say slight theoretical advantage in accuracy, but that is more a function of the individual doing the shooting and the individual weapon. Some will say a slight (very slight) theoretical advantage in reliability, but he bottle-neck design has its own particularly reliability issues (e.g., to "nose-dive")--if anything the tapered designed of the 9x19 is probably more reliable than both (theoretically--again, largely and individual weapon issue). Despite the the internet hype, .40 S&W and 357 SIG (as well as the 9x19) all offer similar intermediate barrer penetration based on actal tests (not tales). As for steel targets, there's a lot a difference in mass between 5 pound steel plate and 250 male--the difference is not so nearly pronounced (and a whole host of other factors are involved. Another important factor (actually to the .40 S&W's advantage) is .40 S&W is usually far more readily available and considerably less expensive than 357 SIG So, bottomline, the 357 SIG offers no actual, concrete advantages over the .40 S&W (but the .40 S&W might offer one or two over the 357 SIG in terms of ammunition availability and price).

No major advantage that I know of. I've been fighting the urge for a KKM .357 SIG barrel for my Glock 24 for years and I've decided to put the money tward a 10mm instead.

Concur with the 10mm.

Also, reloading, to my mind, the key to practice, indicates that no bottle necked round for a pistol/revolver is acceptable.

Still, you pay the price and take your chance....
