.357 Sig vs. 9mm

I would assume 9mm is more plentiful than .357 Sig but do they cost just about the same?

SIG ammo is a LOT more expensive.

cheap, FMJ 9mm=$11.99 per 50.
Cheap FMJ .357=$18.99 if your lucky enough to find Ultramax, $24-26.99 for the rest.

NO real reason, other than the fact they produce less in total, and demand is high for what is produced. Oh yeah, plus they can get it.

The good things about a .357 Sig are these.


1. While more expensive that 9mm, it is more powerful. Some like that for SD. The .357 Sig is used by quite a few PDs, local, state, and federal.

2. For Glocks and Sigs you can get a .40 barrel and just drop it in. Works either way. Even the mags work. Maybe even other .357 Sigs do that.

3. Practice with 9mm factory or .357 Sig is expensive. So

a) reload,
b) get an AACK unit (if it's a Glock) and practice alot wth .22
c) again if a Glock, get a Lone Wolf 9mm replacement barrel and vola! You have the best of both worlds.

In fact, with the chancy ammo market, you can get a Glock with a .40 barrel, .357 Sig barrel, 9mm barrel (and some 9mm mags), and a AACK .22 unit (with some .22 mags) and you have a four cartridge gun! That way, if the ammo situation goes south, you have a much better chance of finding some ammo for your gun!

My local Wal-Mart sells 50 rounds of Blazer Brass 9mm FMJ 115gr. for $7.40. After local sales taxes, its $8.05 (8.75% sales tax). They sell 357SIG also, but I don't own a gun chambered for 357SIG, so I've never noticed what it sells for...

Retail prices for Winchester @ Wal-mart in FL

9mm will run you a $0.225 a round per 100 WWB after tax
357 Sig will run you $0.534 a round per 100 WWB after tax
Compared to
.40 S&W will run you $0.32 a round per 100 WWB after tax

The only up side to 357 Sig is at least in FL you can pretty much find it in every wal-mart around...but I don't see the advantage in spending the money if you have something like a 226 Sig Sauer .40 S&W on a new 357 sig barrel, about $180 and then get to have $0.21 a round more in ammo costs

When reloading 357Sig does the necked down cartridge mean only carbide neck resizing and if you want to full resize you have to lube for non carbide dies?

There is a way aroud it.
On a four station Lee do this:

Station #1-40 S&W carbide sizing die, sizes the case from the sholder down (any make carbide die will work, I use a RCBS carbide die.)

Station #2-.357 Sig sizing die, size the neck and shoulder.

Prime the case on the down stroke.

Station #3-Lee .357 Sig thru the die powder charge.

Station #4-.357 Sig bullet seating die (any brand will do.)

And that will do the trick.

If you have only a 3 station Lee turrent press, as I do, use a single stage press to do the .40 S&W carbide sizing die. Just run everyone of them through this. I put a empty bucket on one side, and a bucket of Sig brass on the other and just crank away till they are all done.

Think outside the box guys!

THe .357 Sig is a much hotter round. You have as mush as 200 FPS faster per round/bullet weight. I prefer the roung to the 9mm. My Sig P229 loves the round! I recommend it to anyone that has a .40 and purchase the .357 sig barrel. You won't go wrong!

I bought a 226 .40 and got the .357Sig barrel for 150.00 at the same time.

I've chrono'd 125 gr. Speer and CorBon at 1400 fps from my P229---considered a short bbl. by most.

Chrono'd some 115 CorBon at 1500 fps from the same gun.

Yes, it's hot, but I've had no trouble with .40 caliber and I've settled on .40 caliber for carry and practice, with my .357 Sig bbl. seldom used. I have a friend who, whenever we shoot, changes his .357 bbl. to .40 for practice, then changes it back to .357 Sig for carry.

I suppose they could be reloaded by using Hornady's OneShot spray lube. It drys on, is non greasy, and, pay attention now, DOESN'T HAVE TO BE WIPED OFF. I use it on all my pistol calibers after reading Brian Enos' recommendation on his site. Sure makes things easier, even with carbide dies.

I have a friend who shoots .357 Sig from his Glock. Quite expensive ammo, although it is available (mostly because the demand is quite low). He will not reload, because he only shoots one or two times per year

I have had about 300 .357 Sig cases for a couple months--can't give them away. Have another friend who reloads and just bought a .357 Sig. I will literally give these cases to him, because nobody else wants them.

It's an oddball round--many call it a one-trick pony. I'm inclined to agree. Much like the .45 GAP, it is really an answer to a question only one or two people asked.

Flame suit on, for all two of you.

I h.ave a Glock 31 and don't really regret it

Of course I paid $300 for it with night sites and 7 mags. I like the 357 round, and used to shoot a lot of Fiocchi fmj when it was only $11 a box. Sig ammo is so expensive now I bought a 40 barrel and use it instead.

357Sig vs. 40SW

My Sig pistols shoot 357Sig slightly better than 40SW ... for ME. Also, Virginia State Police use 357Sig. I'm one of those who practice with 40, but carry 357Sig.

Just make sure your barrel and load are matched up before you load, holster, or fire your weapon.

As others have said, the biggest downside of the .357 Sig round is the cost, over 9mm, and the biggest upside is a lot more power. I reload - but I have two of the basically same gun (Steyr S9 and M357) - I practice with the 9mm the most, carry the .357 the most.

For a good spectrum of ammo comparisons between the two calibers, check my sig.

The question was: 9mm and 357 sig. I never said the 357SIG was better than the 40 Smith, my statement was the .357 sig is hotter than the 9mm. The 40 Smith is far better than the 9mm and the .357Sig. let me put this out there, neither 9MM or the .357 SIG match the 40 Smith, both in penetrations and energy delivered. Lets follow the question and not quote out of text!!!!

By the way, I am a die hard .45 man for carry and protection.

I'm of the mind that if you're going to shoot a 9mm bullet, go with the 9mm. Otherwise you just get a 9mm with the capacity of a 40.

You like perfornance? Check the Nosler reloading manual, the 40 S&W loaded with a 135 gr HP, in front of Longshot powder, either matches or beats the sig round at its best. Since the 40 S&W is 10 grains heavier and a larger diameter, the 40 S&W is now my choice over the sig round,which stays in the safe. Another plus, the 40 has less muzzel blast, IMHO

When you want to take your dress off, drop the .40 Short & Wimpy and get a 10mm.

I kid I kid. Sort of.
