Is the 357 SIG gone?

IIRC, Buffalo Bore has it.

Sometimes, ordering online is your best bet.

Sometimes, reloading is your best bet.
 
SGA has .357 SIG Speer Lawman 125 gr. for $299 for 1000 rounds right now. That ammo is very consistent ~ 1.5" 5 shot group at 25 yds in the S&W OEM .357 SIG drop in barrel in my M&P .40 Pro CORE 4.25" barrel full size.
 
357 sig is about like 41 magnum when it comes to who has ammo . Usually when you find it they won't have a very big selection , different weight bullets and different manufacturers . I and my sister are real 41 magnum nuts . I recently converted my Sig P320 from 9mm subcompact to 357 sig compact using one of the "x-change kits " from Sig , comes right to your front door , no FFL required . I couldn't be happier . I've become a real convert to the 357 sig . It's a fairly easy cartridge to reload , contrary to what some will say .

Amen! I did the same conversion with my SIG P320 9mm. I do most of my shooting with my M&P 40c (my EDC), so the transition to the .357 SIG round was an easy one. I have never become so accurate so quickly with a new caliber, and have now become a hard-core .357 enthusiast. My P320 was mostly gathering dust as a 9mm, but now I'm firing 300-400 rounds a month with it as a .357. I'm thinking that the 1300+ feet per second muzzle velocity may have something to with the .357's accuracy. Since accuracy is paramount when shooting, I'm not sure why this round isn't more popular, but as long as ammo makers keep producing it, I won't care what others do or think.
 
Underwood has some really strong .357 Sig cartridges with name-brand bullets. Sellior and Bellot does a 140 grain FMJ that makes a great field or practice round. Target Sports USA frequently has great prices on .357 Sig practice ammo (typically Speer Lawman).

I became a senior firearms instructor back in 1990 and I own two pistols in .357 Sig. It is much stronger than other service calibers producing around 500-600 ft lbs of KE depending on barrel length, yet is the same size as a 9mm pistol. I have never experienced a failure of any kind with either of my .357s (Glock 32 and 33) in twelve years of use.

Departments have to have pistols that work for all their officers, so they use pistols with a cartridge that satisfies the lowest common denominator. IOW, something with light recoil. However, when the risk of failure creates an unacceptable potential outcome, the .357 cartridge shines like a new penny. That's why the Secret Service continues to use it. Think of it as a demi-magnum...
 
I think the biggest problem for .357 Sig use in LE is the cost. It's more expensive and I really don't know why. One of our local PD's uses Glocks in .357 Sig. However, for whatever reason, the Mississippi Highway Patrol recently went from .357 Sig to 9 MM. I have several pistols in .357 Sig and have no problem with them.

It's a catch 22. It's not more popular because it's more expensive and it's more expensive because it's not more popular. The Great Obama Ammo shortage hit it really hard in the civilian market. With the all the research money being put into 9mm ammo .357 sig isn't any more effective and nothing is cheaper than 9mm.
 
I think it is easier and cheaper to find online than in most stores...I think part of the movement away is akin to the movement away from .40 S&W...there are a lot of excuses, some real and some imagined as to why there is a move to the 9mm...

as to performance, I think that the 357 SIG did exactly what it was designed to do, sold to exactly who SIG was trying to reach along with a lot more...it just seems to have fallen somewhat from favor as has the .40 S&W and to some extent the .45 ACP...

I like 357 SIG it's just that the gulf between calibers seems to have narrowed since it's introduction...

Good luck with your choice.

I skipped to the end of this thread so forgive if I repeat. To all those folks out there asking if their particular 9mm will shoot +P+ or how far you can push the data on reloads and all other inquiries as relates to getting more bang out of a 9mm...my reply was always if you want more bang than your 9mm is providing then you need a bigger caliber, not more juice in your 9!

Well, that's exactly what a 357 Sig round is... a 9mm on steroids! It shoots a 125g 9mm sized round 500fps faster. So for all the opines that the 357 Sig has no market I'm absolutely stunned that the 9mm Rambos haven't picked up on it!

For the record I have the M&P 357c and love it.
 
Only place I can find any is on line. Local store doesn't stock it any more. None at the local Dunham's either. Is the caliber dying out?

The what? Oh! The .355 Sig. I know every manufacturer wants their own proprietary gun/caliber, but I would have been a little more interested if they had called it what it is.

Well then a 9mm would be called a .355. So I think there is a reason for the different name.

So why not call it the 9mm Sig?

9x17= 9mm Kurtz= .380acp= .380 auto= .355in dia
9x18= 9mm Makarov= .364in dia
9x19= 9mm Luger, 9mm Parabellum, 9mm NATO= .355in dia
9x21= 9mm Largo= .355in dia
.38 super= .355in or .356in dia
9x23= .355in dia (basically a .38 super magnum)
9x29= 9mm WinMag= .355in dia (designed for semi auto pistol from AMT, and LAR)
.357 Sig= .355 (.40S&W case necked down to accept a 9mm/.355in bullet)

Oh that's why. Nevermind :p
 
Of course getting the attention of those at the time holding on to the .357 Magnum is what necessitated the name...it got many to move who wouldn't normally at the time consider 9mm anything.

M&P Conversion .40 to Sig .357

Use a KKM barrel, same magazine can switch out in about 3 minutes. Load both calibers so always have enough ammo.
Like having two guns , only one registered.
Converted my Sig 226 .9mm to .22 with the sig conversion.

Did or does anyone make a .357 SIG conversion barrel for 3rd gen Smiths?
The beefy 5906 or 4006 would make a good candidate for such a conversion. I'd love to convert my 5906 to .357 SIG.
 
I am a true fan of the .357sig, NEVER an issue with it. I like to mailorder my ammo so i have a constant supply.
 
It's not dying. It just didn't succeed as far as SIG hoped. But a long way from dead.
Too many LE agencies adopted it, and regular folks who own them, swear by them.

Availability of guns and ammo on local shelves seems to vary regional, appearently I'm in a hotspot, because I see .357Sig at least as often as I see .357mag. Not much "variety" , but face it, the cal is built around 125jhp.

The .45GAP currently has one foot on a banana peel. But if the*right * gun gets introduced AND put into full production, it will give the same boost that Delta Elete did for 10mm.
