Not for everyone or every situation but it is great fun (at least for me) to shoot.

Thoughts?

I like it better than either 9mm or .40 S&W. I also like that it is relatively cheap to reload as the components are so far easy to find.

Early on the range used to have many 357Sig cases lying around, I scooped up quite a supply back then and decide to get a conversion barrel chambered for the G-29.  Therefore I got into loading and shooting it!  I also got into the 9x25Dillon just because I like playing with with the different cartridges from the same guns.

If ever my friend gets back to the CNC machines, I have a 357Sig barrel being made one for the 1076 4.25" and one for 1006 5".

I see no need (for myself) for a 357SIG. It took me 13 years to get a 40S&W, and the only reason why I got one was so I have something to shoot when only 40S&W ammo is on the shelf. I actually just bought a 40S&W slide and barrel for my Beretta 92. If I ever decide to go the bottleneck route, I will get a 9x25 barrel for my G20. I figure if I am going to go to a 357 SIG I might as well go 357 SIG plus a little extra.

The sig often offers less penetrantion than a .40sw & .45acp.  It's permenant wound channel is equal to, and or less than 9mm plus P.   hot commercial loads generate 1400fps / 550ft_lbs of energy. 

The glorious 10mm matches / exceeds it in trajectory, wound channel diameter, energy & power factor. 
The 10mm can be had with a controllable 400ft_lbs to nuclear 760ft_lbs.  from rabbits - to bears.

The .357sig is an an acurrate round, but it's uses aren't as vesatiled as our ten. 

As fore mentioned, if I'm going to shoot a fast .357/9mm caliber, it'll be my 9x25. 2000fps & less muzzle climb than sig or 10.  Add a compensated barrel and I'm grinning.

The .357sig is a good round but I love 10mm platforms.    !!!!10mmfirearms dot on!!!!

I wasn't trying to compare to the ten.  As far as penetration, you need to read up JUST a bit:

https://www.youtube.com/watch?v=lK6KbA-HuZ8.  tnoutdoors9, the tester in this video, said it was one of the best test results he had seen (other than Hornady's 10mm XTP.  This puts ALL 9mm to shame.



Here's a list of all the State Police in the US Duty weapon & caliber (from GlockTalk)

The thread has some good info, notice only 2 use 9mm

Right on buckeye 50.   357 sig blows the 9 away and is one of the best performers on tests. Those test TN OUTDOORS does are impressive.   Makes me want to get a Glock 32 for sure.

This may help explain the 357Sig as well...9x25Dillon also...

.357 Sig is a good round but the 9mm can perform almost as well depending on what round you use.  These are very impressive tests done by tnoutdoors9 also.  Speer does make a factory LE +p+ 124 gr 9mm load also.  If you watch until the end or have seen enough gel tests then you know that higher velocity with the same bullet cause more expansion and a faster energy dump.  The question is whether you want more penetration or a more violent, and likely more damaging bullet track due to higher expansion, round.  I see and agree with the choices made by the LEO community, but keep in mind they are more likely to need to shoot thru materials like a car door or a windshield than we do using a firearm for self defense where the situational stress affecting shot placement and hit percentage makes the available number of rounds in the magazine very important.

Here are some interesting videos of him testing 9mm loads, with him comparing the UW +p+ 124 gr 9mm to the .357sig.

Quote"A bullet cartridge rely's on the venturi effect to increase the speed of a bullet as it is fired."

That makes no sense. Bullet velocity is dependent on the amount of force applied to the bullet. Pressure is equal to force over area: P=F/A. Using 6th grade algebra would make Force equal to pressure time area: (P)(A)=F. Since the pressure starts out high and drops off, the force also starts out high and drops off as the bullet travels down the barrel.

The venturi or Bernoulli effect has nothing to do with it.



.

my_old_glock, I'd be inclined to side with you on that, I found that link on facebook this morning.  I placed it here for question...

The venturi effect has to do with fluids in motion, air & gases can also be considered a fluid.  The cartridge and barrel can be looked at as a closed container behind the bullet even as it is moving down the barrel, the propellant charge is that of an expanding gas, it builds to a peak spike in pressure and tapers off as the bullet travels and then exits the barrel.

As a fireman, I used the venturi effect to siphon fluids like foam from a 5 gallon can to be introduced to the stream of a hoseline.  The venturi develops a lower pressure area, thus the atmosphere being of higher pressure, pushed the foam up into the venturi opening to be introduced in the flowing stream of water.

While the picture and article show and compare the rifle round to the venturi or Bernoulli effect, the system is closed and has no opening as shown to allow a lower pressure to be induced by any movement of the gases therefore it has nothing to do with rifle or pistol cartridges as such.

What is happening is actually allowing the pressure to build to higher pressures, over a longer period of time due to the reduced opening, thus acting on the bullet longer before it bleeds off...

Good call my_old_glock!

Apples to Apples.....the 357sig out performs the 9mm in every case.

Now, if you want to compare max loads to semi-max loads, feel free; but when apples to apples....the sig exceeds 9mm every time.

Very true

Red Baron,

I wanted to add this to start with: you are correct and I absolutely agree on the apples to apples, but both cartridges use the same .355 bullet.  The 357sig has more case volume for powder, thus has a higher velocity potential.  All I was pointing out was that there are 9mm rounds available to purchase that meet the ballistics of the standard .357sig rounds (obviously you need to know the capabilities of your firearm to be safe shooting +p+ rounds).  I am not looking for a which is better argument, but rather simply stating and showing that the same bullet shot from either cartridge with the same velocity and bullet weight have a very high probability of inflicting the same damage, whether in gel or flesh. 

Isn't this what makes the 10mm round so versatile?  You can get a light, super fast round or a big, slower round that suits your desires or needs.  It is comforting for me to have 14+ rounds of 41 magnum like power.  I don't have to have nuclear rounds loaded, but I can and this is also why most people on this board were happy to see Federal come out with the 180 Vital Shok with a good velocity that made it a true 10mm round.  Again, I am not saying they are apples to apples, but e=mc2.

Remember, I am not looking to argue and that is what makes this forum the place I go to.

No problemo.......I'm not arguing which is best either, but many try to make the case that one doesn't need a 357sig; you can get the same from some 9mm loads. This is partially true; however, most will not shoot a box of that stuff through their gun during their lifetime. My target loads are a 1300 fps, which is fairly close to high end 9mm. My carry loads are at 1475+.

I love the 357sig and 10mm round for their high-end out-put in a semi-automatic hand gun; plus their ammo versatility too. Is one better than the other...that depends on the one's preference. I have a G26 that is carried sometimes; I float between loads, 125gr or 147gr, depending on the year. I will let each person make the determination that is best for them by letting the data speak for itself. There are some who don't want those high end loads, that is fine.

I have to admit, I interpreted your comments as the 9mm is equal or better to the 357sig; hence my response. I don't advocate one is 'better' than the other; but when I here/see the comparisons, I just like to point out apples to apples.

My apologies if I came across a bit rude.....it wasn't my intention...it was just to match apples to apples.

I appreciate the civility.
