I'd recommend going with whatever round is most common in your locale. I'm willing to bet it's .40, but I could be wrong. The .357 Sig is a great round, but can be harder to find. As far as magazines, as far as I know, both calibers use the same magazine.

I have both barrels for my P226. I reload .40 so that gets the most work being with the necked case .357 is much more difficult to reload and brass difficult to find. The .357 has better controlable recoil not as snappy and for the most part penetrates better than the .40.
My best case scenerio is practice, compete if you like, and you can drop in the .357 barrel if you want a more effective carry round.

I love the platform, hate the price and availability of ammo.

Cost of .357 Sig ammo.........way to much and hard to find...

I own a SIG229 that came with .40 and .357sig barrel. I shoot the .40cal ok. So far, I only tried the .357sig barrel once, and it was WAY too much for me. The difference was amazing. I have pretty much given up on .357sig for now. At the time I tried it, I was at a range with fixed targets at 15yards. No problem hitting them with .40cal, even with some speed. For the .357sig, I had a hard time hitting the target at all. Adnt eh 229 Sig is not a light gun (about 2lb). I don't want to know what it feels like in something like a compact Glock.
Lots has been written about the advantages of the .357sig bullet over .40/9mm. Some say it is too fast, and it is hard to have the bullet not fragment. My non expert opinion is that it is more of a bullet that you use if you need a bit more penetration then you get from a .40. For example shooting at targets wearing light armor or inside a car. But for regular self defense stopping power, a .40 or even a 9mm should do the trick about as well as a .357sig.

m&p .40 ftw. i love mine and before purchasing it i looked at ALOT of other .40 pistols and overall, as far as weight, capacity, price, safety, sight options, size and other things it takes the cake. Other guns just dont stack up. Sure sig is nice but the price is kind of insane. As far as .357 SIG i havent looked much into them. Just my .02$

G33. It's my daily carry and wouldn't be caught without it. Easy to conceal, easy to shoot and hits like a truck.
You'll rock, with a 357 Glock
Many reasons to start with a "4". The M&P is a nice compact.
What if the Hokey Pokey IS what it's all about?
[QUOTE=pogo2;1071594]I've read what I could find about the comparative ballistics and gel testing of .40 and .357 Sig, and can't see any advantage in the .357 Sig over the cheaper and more available .40.
I cant believe tha an Extra 500 FPS aint gonna make a huge Difference, I have one of each in the S W M&P Compacts and even out here in the Back yard you can see the difference at the point of Impact so I think the guys doing the test must be on Crack. Get An M&P in 357 Sig u want be sorry, and ammo around me is just as easy to find and aint but about 2 dollars a box more for FMJ its well worth that trust me.

I agree w/ most of the posts. The .40 is definately cheaper and easier to find. Both rounds perform well. Although I would worry a little bit about overpenetration w/ the .357 sig.

It is better to have your gun and not need it, than to need it and not have it!
You cannot choose the conditions for a gunfight, so train in all conditions!
First, you should honestly answer (to yourself) how much you actually practice with your weapon--not how much you want to practice, but how much you actually do. If the answer is "not so much", then I suggest getting the 40 caliber with a .357 barrel to "mix-it-up" more. The fact that the .357 ammo is expensive won't matter very much. If the answer is "a lot", then get the 40, but pass on the .357 barrel both because the .357 SIG ammo is expensive relative to the 40 cal and not easy to reload because of the bottleneck case.
There is a significant difference between shooting the .357 and the 40, but not much difference in effect imho. In either event I think a SIG 229 is the way to go.
An alternative that may be possible for you (if you are not overly concerned about ammo cost) is to get a 40 CorBon barrel for your Colt. This caliber is a 45 necked down to 40. This can let you mix it up without buying another firearm. I don't know if anyone makes a 40 CorBon barrel for a Defender. Of course, doing this would not give you near as much pleasure as buying another firearm.
As mentioned before, most makers allow for the swapping of the .40 S&W and the .357 Sig with just a barrel (and sometimes a magazine) swap. If you're curious, just buy one of these and then get the other caliber's barrel to see if you like it as well.
