Seriously looking at .357Sig vs. .40S&W

For a carry gun, I'd rather have an 8-shot P239 in .357 Sig with superior firepower, ballistics and shootability than a five shot .357 mag snubbie revolver. I'd dress around the gun. But that's no slam on the revolver, my house gun is a 2.5 inch 686 Plus. Different tools for different jobs.

But going back to the original question, I'd get the P229 with .40, .357 Sig and 9mm barrels. The best thing about that platform is it doesn't have to be an either/or proposition.
 
.357 SIG VS .40 S&W

Well, now I recently had to make a similar decision, so I got a Sig Pro 2340 in .40, and will be getting a drop-in .357 barrel ($160)

So now I have either depending on what I want, who's having sales, etc...

Added bonus is the same magazine will hold ten rounds of either cartridge.

Downside, a magazine will only hold ten rounds.

With all of these arguments for both sides, I'd say you're probably splitting hairs between either one as far as effectiveness goes.

The .40 will be cheaper to shoot, and much less of a pain to reload for. The Beretta .357Sig that I shot had the sharpest recoil of anything I've fired including a scandium .357 firing Corbons. I wouldn't enjoy shooting that regularly. In addition, one of the indoor ranges that I use doesn't allow .357 Sig, but .40 is okay.

For sheer cool factor, the .357 Sig wins.
 
I don't like the 239 because it has a mag capacity of only 7 rounds. i don't like the 225 for the same reason, mag capacity is only 8 rounds.

right now i'm debating whether i should do 1 of 3 possible things.

1. just get a p228 (west german version preferable).

2. get a p229 in .40SW or .357SIG, and get an aftermarket 9mm barrel.

3. get a p229 factory 9mm.
 
If you like sigs I would get the 229. I believe its a very fine combat handgun and its my faviorate of the DA autos. It was my first centerfire pistol. I am now a glock fan but sigs are still fine pistols. I got rid of my 239 for a glock 33. But that 239 was a damn fine gun.

I will pretty much side with Pat on this one. I like the 357 Sig. In its lighter loads, 125gr, it has the authority of a 125gr 357 magnum. Does it kick in my Glock 27 with a 357 Sig barrel? You betcha! Recoil, noise, and muzzle flash. This is probably why I like it. In my neck of the woods, Michigan, I can buy 357 Sig ammo much cheaper than 40 S&W. If you get the idea that I like the 357 Sig you are right. Regards, Richard
 
WeShoot 2,
Ditto. That's what I did with my G32 and FA 40 BBL. Nice tight chamber on that 40 bbl. Very accurate.
 
ump45, I don't want to throw even more uncertainty into the equation but before buying any other SIG a person needs to at least test the trigger action of a Pro and compare it to the one they want to buy. It is very enlightening.
 
NO get a .40 auto first, then a 357 SIG barrel for it. That's what I might do with my Glock 27.

OK, joking aside... I no longer feel the need to go with the other barrel. The .40 is "good enough." I prefer the .45.

I mean this topic is literally getting down to the very, very skinny. Smaller diameter, lighter bullet going faster. Heavier, larger diameter bullet going slower. Which do you prefer and why? Either should do it's part if you do yours...

In my personal experience, I have seen only 125gr 357 SIG ammunition available. Have seen everything from 180gr to 135gr for the .40. Not a big deal, but it is nice to have the choice to go with the 180gr FMJ for deep cover penetration or 135gr HPs for a Glaser-esque effect...

You don't need to change bullet weight to get less or more penetration and fragmentation. A 125 grain federal or gold dot penitrates as much or more than a 180 grain 40 jhp. While a 125 grain corbon load acts like a 135 grain 40 load. All with the same bullet weight. The Ranger load is right in the middle. Also you can get 115 and 147 grain weights in the 357 sig. In all reality your better off picking one load and sticking with it rather than changing loads.

Agree 100%. The load I stick with in .40 is 165gr Gold Dot. If I were as adept with a 357 Sig pistol (or bbl) as the .40, I would not think twice about its effectiveness.

Sounds like the 147gr Sig round would penetrate scary deep...
 
357 SIG FIRST

That way one is assured of getting the most modern, engineered version. 357 operates at higher pressure than 40 (if all goes well) so this is the correct direction.

And remember 9mm has different breech 'cause it's SMALLER!
