[ARCHIVED THREAD] - School me on .357 SIG

Posted: 10/2/2014 10:41:21 AM EDT

I have a Glock 23 with a 9mm conversion barrel, and I've been thinking about picking up a .357 SIG barrel for it. I don't know much about the caliber, except that it's more expensive. Seems like all the caliber discussions here center around 9/.40/.45, and I don't see much love for the .357 SIG. Is it worth it? Are there any advantages?

The answer to a question no one asked.

it is the actual plasma rifle in a 40 watt range that this guy wanted

It is very loud. It is very snappy.
Take the annoying snappy of the 40, and +p it.

Also, in my experience with it, if you load a round a couple times, like taking your carry ammo out to practise, the round can start to recess in the case.

It is a cool round for sure. But really, if you want more power than 40/45 and "different", go 10mm. It is on a 45 frame, built to take the punishment. Also .357 gives you more velocity, but less weight than 40. Where 10mm gives you .40 weight at higher velocity.

It's still just a .355 and it always will be!

ok seriously it is a 40 cal case necked down to hold a 9mm bullet.

it is screaming fast and very accurate, however advances in 9mm bullet tech have caught up so most of what it offers is possible with current quality 9mm JHP ammo

Bullet diameter of the 9mm, recoil and muzzle blast of the 40 S&W.

Worst of both worlds.

ETA: I am a converted 357 SIG Fanboi.

It's a 9mm in a .40 cal case. It's expensive to shoot. A GP100 looks more fun to me.

If I picked up a bottleneck pistol cal, I'd want a 9x25 Dillon. It's a 9mm in a 10mm case.

It's a snappy little guy. I think it is a very cool cartridge, but it is harder to control.

ETA: In before the commandos tell us all about how it's not a 40S&W case.

How much of an advantage does it get over +P 9mm?

I haven't looked in a while, so it may have changed. But the last time I checked, 357 sig was 200-250 FPS faster than 9mm iirc. The .357 Sig is a .357 mag performance in a semi auto pistol.

I don't see the advantage over a 9mm(+P+) round with a similar bullet weight, assuming your 9mm pistol will safely function with them.

How does +P+ compare velocity wise?

I converted my .40 Glock. It's loud and snappy (not a problem for me) and fast, flat and accurate. 1450 FPS is pretty nice.

I've got a Glock 32 and 33. It's less recoil than .40 IMO. There is a lot of noise and flash. Many highway patrol departments chose it since it deflects less through windshields and offers great penetration. The US Air Marshalls and the Secret Service carry it. I have a 9mm barrel for cheap range blasting but if I want to shoot at longer range pistol targets or carry them I use the .357 SIG barrel. There are a lot of haters though.

Posted: 10/2/2014 11:06:12 AM EDT

[#16]

I own a G31 and I find .357sig very easy to shoot. It has a bit more "umph" but not uncontrollable. I find it very easy to put multiple hits on target. Depending on bullet choice, it is a great for penetration and to defeat barrier protection. Still, in the end, it is only a handgun round.

You have the .40 so it doesn't hurt to just pick up the barrel for it, especially since you won't need new magazines either.

The advantage being you will have one gun with the ability to shoot 3 calibers if an ammo shortage happens again. I was ALWAYS able to find .357SIG for the Glock 32 when everyone else couldn't find crap for their 9/40/45's. It's another option that only costs $100 for the barrel. I did this for my 32 and never looked back.

Think of it as a 9mm+P++

Underwood Ammo:
.357 SIG 115 gr: 1550 fps/614 ft-lbs
125 gr: 1475 fps/604 ft-lbs
147 gr: 1250 fps/510 ft-lbs

Old timey cops missed their .357 wheel guns. .357 Sig gave the old timers the power of their old .357 with at least double the capacity, which made them squeal with delight. It really is cost prohibitive compared to 9mm with only marginal performance gains in ballistics and loses big in handling due to recoil. A Sig 229 is heavy enough to where it feels like you're shooting warm 9mm, but in a Glock especially a compact you're really going to fight the recoil to run it quickly. You would be better served getting a 9mm conversion and buying twice as much ammo for the same amount of money you would spend on .357.

It works just fine with the same followers. No issues at all.

This pretty much.

Our local SD carries 31s and 33s. Head firearm trainer says it adds advantage that if there is an OIS that their rounds are pretty easily identifiable because its not something every Joe is carrying.

Ballistically it is a freight train, but not sure with ammo advancements and the added snap it is worth it any more.

I'd love an MP5 chambered in it!

I have seen local deputies shoot quals and no I don't mean standard paper punching quals, actual run and gun shoot and move stuff prove you wrong. The detectives carry 33s and routinely outshoot the guys with 31s.

I think it's a very cool round, but the numbers don't lie:

Its LOUD but very accurate and very little recoil in a P226 . Plus if you hand load it can make a hell of a varmint round 90gr@1785fps out of a 4.4" barrel

I must have this 90gr load

I wanted one for God knows what reason. I actually have more .357 Sig ammo than I do anything else. Out of a 226, its very manageable, but like it was said, loud and flashy. It's among my favorites

I've used a couple of these and they are spot on

So basically what I get out of this so far, is it's pretty much a 9mm on steroids. I think I might still pick up a .357 barrel, just to have options in the event of the next inevitable panic. For $100, why not?

I had a 32 for a while and it kicked ass. It was the most accurate Glock I've ever shot. Snappier than a 9mm, yes, but not as snappy as a .40 in my opinion. I don't get the naysayers talking about too much recoil. I didn't find that at all. And I consider myself somewhat recoil sensitive.

I loved shooting it, problem is ammo expense and I wanted to consolidate down to just 9 and 45. So I traded it for another 19. In retrospect, I should have just got a 9mm barrel and kept it. I really liked that gun.

I have a .357 Sig P229. I really like the round, it is super accurate and doesn't vanish during panic buying like the more popular calibers do.

Posted: 10/2/2014 11:58:27 PM EDT

[#37]

I have a G32 and G24 with conversion barrel, a little over 800 factory rounds. It's a stout little round. Pretty fast back on target when shooting with my G32 but uncomfortable when shooting with my G24. Haven't shot either in quite a while and never back-to-back but I may do that soon to compare.
