.40 s&w VS 357 sig in Ballistics Gel 

I've said it before and I'll say it again, .357SIG is the most impressive SD round on the market. Great work, Az.

Very hard for any conventional round to compete with a bottleneck high pressure round...the 357sig ONCE again dumping more kinetic energy into a target more than the 40sw...great tests AZ!!!! 👍

I have both. I actually bought a Glock 33 in 2012 and Glock 31 in 2016. Couple years ago, I bought .40 S&W barrels for both. Ammo is easier to find and easier on the wallet.

The .357 Sig is ballistically identical to the old .38 Super. The big attraction is having interchangeable barrels with .40 pistols.

Great video to prove the "bigger is always better" crowd wrong. Bigger rounds may provide larger direct tissue-crushing holes, but as you can clearly see in this video .... the 357 Sig round had a notably smaller expansion diameter for direct tissue-crushing... yet the cavitation was notably greater.🔥

would be nice if the 40 was actually loaded to get the advertised velocity. the extra 115fps makes a difference. but the sig is always impressive

I already knew that the .40 S&W was a hard hitter with a gruesome wound cavity, but that .357 Sig is scary impressive. Faster, greater wound cavity and deeper penetration. If it weren't for the cost/availability issues with the .357 Sig {in some cases, twice the price} I would carry it as my edc, but you have to be able to afford to practice with the handgun you carry. For now, I will stick with my Glock 23.

Recently switched from 40 to 357 sig a lot people don’t know what it is I’m happy

.357 sig is my EDC go to, but that .40 looked very good. That 155 really had beautiful expansion, as HST usually do. .357 sig is just amazing. Double Tap has a solid copper hollow point in .357 sig that's 115gr. rated at 1500 fps. Would love to see that one put through your testing protocol. As always thanks for the test, and have a wonderful day.

Love the 357 SIG

2 very impressive rounds indeed. I own a Glock 22 and I do really like the .40 S&W. Of course I would love to get a handgun chambered in .357 Sig but the price and availability of the ammo is what is stopping me right now. I hope that .357 Sig would start gaining popularity because it seems to be a very capable round. Maybe it will end up like 10mm and gain a following and make a big comeback.

357 Sig is harder to find, it's more expensive, and a 9mm projectile in a 40 case will give you those results, especially out of subcompact guns. But the USSS armorers describe it as a gun eater. P229 with more than 10k rounds weren't warrantied by Sig.

Excellent performance from both rounds, quality stuff. 👍

Wish you would've the same gun for both ammos an just dropped a 357 sig barrel in the Glock 27

Thank you for another great video.👍🏽

Another great, practical comparison video between two top carry rounds! Great to see the different barrels, especially the short barrel tests! 😀 We get to see the results and yet it doesn't cost a penny for such valuable resources of information! It takes alot of time , work , and effort to do what your doing, and I very much appreciate it!

Another excellent test with great results. 40 for the expansion win but energy, damage & penetration

Es una suerte que uds en USA consiguen cañones de calidad para usar con una misma pistola. Tengo 23/27 desde hace muchos años. Si Magtech hubiera fabricado .357 SIG tendría una pistola en .357. Pero aca en argentina entra poca munición, poca variedad y cara la .357. MAGTECH hizo 10 m.m. y fué un éxito las ventas de las Glock 20. Así ayuda a una Región cuando una empresa del prestigio y la excelente calidad de Magtech hace tal, o cual calibre. Disparo a veces con la Glock 31 prestada y me parece un sablazo cosaco ese formidable calibre...✌️

Thanks for the short barrels!

Very complete, very interesting and nice pictures. 2 sizes comparaisons relevants. Hi from France!

Modern loading of a .38 super is similar to the sig . 10 auto and 400 corbon are very similar .

Instant sub. Thanks for doing good tests and using REAL ballistics gel instead of the clear synth crap.

All things .357SIG #hardesthitting

I don’t wanna be shot with either! That sig is bad but that 40 looks mean too!

Love em both ....Gen 5 Glock 23 is a sweet shooter

.357 Sig is my EDC.

Nice test lukewarm SiG. How about doing a 357S 125gr JHP vs 9mm +P+ 90gr XD in G33 length barrels. I bet it’s dead even. I’m saying the XD boosts the terminal performance of the 9 equal to the original SIG design parameters. Having said that a full size frame (over 4”) loaded with 357S/XD produces next level 10mm/JHP tissue disruption.

That FDE frame looks awesome. Where you get one like that?

This test is very relevant since the .40 is the new .45.

Oh Yeah!

Simple to say all the 9 mm ballistic testing technology has trickled to most all the rounds. the 40 penetrates perfectly slightly better than the sig., larger diameter too. Advantage 40.

👍

Federal HST's never disappoint. Too bad the 357 Sig never caught on. All of your testing demonstrates the effectiveness of the cartridge. But due to its expense and limited loads, I'll stay with 40 S&W. It has lower kinetic energy but more momentum. When steel plates are shot, momentum becomes apparent.

Anyone know where the cheapest 357 sig is online?

Bro I'll PayPal you to send me rest of those Forty I mentioned them in My Cops Should go back to .40 vid coming out this Saturday...I'm serious woukd you? Also yiu should prob post HST and grains in the title

The .357Sig uses 9mm bullets which are designed to expand at lower velocities out of a 9x19NATO so when you run it out at a couple hundred FPS fasted you are going to get somewhat larger expansion from the .357. Likewise the .40 is losing its popularity and the R&D is not going into it so you won't get the newest cutting edge bullet designs in .40 while the newest 9mm bullets can be put into the .357Sig so it will improve as time goes on but the .40 will trail behind to some extent

Good ass aim tho

best testing channel on YT at this point

When. A round fours through a block of gel. Does that mean its still lethal for the people Behind the bad guy. I don’t wanna stop a robbery and end up killing a grandma who was wrong place wrong time.

Both might hurt just little. Buff right out. lol

I just don't understand why the 357.sig is not more popular all you can find them in now is glock and I heard glock is going to stop making them not sure if thats true or not.

.357 is nothing but a .40 S&W shell casing with a 9mm bullet have the best of everything .. Power - Speed - Accuracy

I picked up a mid 90s sig p229 in 40 because in a firm believer in the 40. Ive been reading a fair bit that you can switch to the 357sig round with a barrel swap. Going to send the pistol in to sig to give it a good look over and replace anything needs replaced and possibly refinish the pistol to make it look new. Really tempted on being able to switch so easily
