Everyone has a favorite caliber. But tests and numbers don’t lie. The .38 Super has an edge on 9mm, the .357 SIG has an edge on .38 Super. What really matters in the defensive world is accuracy.

[@grizz474]

Because 9mm is cheaper to shoot, is a great self defense round, fits more rounds in the same size gun....and you can get a 9mm platform in a smaller more shootable firearm than either a .40 or .357sig. However; My favorite pistol is my duty sized XDM .40....love that gun.

[@sombra6153]

Underwood has certainly put a lot of development into both loadings. I’m curious about a head to head between the 9mm 9BPLE or Winchester 127 against a 125 grain Gold Dot in .357 Sig. Those loadings had been around for quite a while.

[@robpelick7460]

9BPLE is the round that made the 9mm not suck. I conversed with a LEO who used it on the job. His comments convinced me to buy a case of which I still have several boxes. I cherish that stuff and frankly, have no qualms about using it as my carry round today.

[@sombra6153]

@@robpelick7460 It was my first 9mm issued duty load in 1991. Ballisticslly similar to the Federal 110 grain .357 that was the issues round for revolvers where I worked. I don’t carry it anymore but it was a great performer in its time. Personally think the 124 grain a+P Gold Dots or HSTs are just as good as they benefit from technological development. The Gold Dot +P is running close to the same velocities as Hydra Shok 124 grain +P from the early 90s which was also a duty load. But the 9BPLE is certainly not obsolete.

I have had people in the pistol & rifle club I belong to try and tell me the close to the same thing... That "standard" 9 mm is "just as effective" as 357 sig. I saw a video sometime ago a comparison between 124 grain 9 mm and 125 grain 357 sig through a chronograph and ballistic gel. The nine-millimeter didn't even come close in velocity or effectiveness on the ballistic gel compared to the 357 sig... But there's people still say 9 mm is just as good as 357 sig. I don't even argue back with them

[@amazingamerican3958]

The people at your club are probably talking about stopping power. I found a study comparing real world gun fighting situations that calculated the number of shots to stop an attacker. The study found no statistical difference between the major handgun calibers .380, .38 special, 9mm, .40, .45. There was a slight increase in stopping power with .357 magnum, but it wasn't much.

The sig is more powerful all day every day. Probably the most underrated pistol cartridge.

[@GunSam]

Seems like about 1990 was the cutoff timeframe where no one wanted anything new. All throughout the 20th century everyone ate up all the new stuff like .357 Mag, .44 Mag, .454 Casull and everything else. The 10mm and .40 S&W barely got in, now after that no one cares. No one cares about .357 Sig, .327 Federal, .30 Super Carry and the other dozen or so new and good cartridges. Probably the fault of polymer high capacity 9mm pistols. Once they became a thing that was near 100% reliable, caliber debate went away. Now we live with 9mm fanboys comparing all their 9mm pistols that frankly look all the same to me. The good old days were more fun.

[@nokoolaid]

@@GunSam Sam: It's funny. The argument I hear from the 9mm fanboys is that under 600 ft/lbs, the efficacy isn't any different among the cartridges and we might as well get capacity with that in mind. One, if that's the case, the 30 super should be flying off the shelves. Two, I think that it's more than just energy level RE effectiveness. I tend to lean towards the momentum crowd. Yes, all the Mattel® pistols look the same, much like SUVs today and yes the good old days were more fun. There were times I had my Blackhawk in 45LC or 4" python and never felt bad about it. Then again I drive a Challenger RT Scat Pack 1320 daily, so there's that. Thanks for the response, I appreciate your work.

[@GunSam]

I get that a lot too, in the form of "all handgun rounds are the same and ineffective compared to a rifle". The real world still exists, and I have seen a ton of police body cam and older dash cam footage, and 9mm seems to do almost nothing to an attacker other than killing them 5 minutes after they were shot and taking that long to make them stop fighting or running. All the while all the footage I have seen with .40 S&W and .357 Sig, is people falling over. Typically 1 shot of .357 Sig or two shots of .40 S&W. The real world footage of .357 Sig I have seen mirrors the stories I have heard about .357 Magnum. I do not know why a 124 gr bullet at 1,250 FPS seems so ineffective yet that same bullet weight at 1,500 FPS is super effective, makes no sense....but the footage doesn't lie. My only guess is that in my ballistic testing, a lot of .357 Sig ammo of that weight tends to explode and fragment, but at 1,200 FPS that rarely happens.

You have options.

It's all about bullet mass and shape, the 10mm and .40 S&W can use 180-220 gr flat nose hard cast ammo which penetrates deep, more so in .40 S&W than a typical .357 Sig bullet.

[@garyglenn5233]

People that are convinced that the 9mm is the only caliber worth having have never studied ballistics a day in their lives. As a cartridge nerd for over 50 years, I can tell you that the 9mm isn't that good of a round. That's why the very first thing that 9mm fanatics say is capacity. In reality one round of 357 Sig has a far better chance of stopping a threat than three rounds of the hottest 9mm loads available. The Sig is the semi auto version of the 357 mag and nobody that has even bothered to look at the FBI one shot stop stats can honestly say that the 9mm is even close to the 357 mag in terminal performance. They're just going by what they've heard or seen on KZbin channels that are solely committed to making 9mm videos. I've shot most of the calibers made over the past 50 years and can tell you from personal experience that the 9×19 is just not that good. It's basically a +P version of the 9×18 Makarov and I've never heard anyone claim that the Mak is a great round. Before someone blindly believes that any caliber is the best, do the research yourself and you might be surprised by what you find.

[@GunSam]

Yes. And it's one of those things math cannot explain to people. Frankly I have no way of explaining it myself, that how can the best 9mm round at maybe 1,300 FPS not be that effective, yet 200 FPS more like .357 Sig/Mag, becomes a fight stopper? I can never answer people with that other than, that's just the sweet spot for adding more, and the proof is out there that this 200 FPS more takes it from 9mm's 5-10 shots to stop a threat, down to 1-2 shots to stop a threat. Some things you don't have to understand to take advantage of and benefit from.

Sometimes it's only an availability issue. We can always get 9mm in just about all flavors pretty much anywhere in the country.

Historically , there was a grain of truth to the " 9mm +P+ = .357 Sig . ( Clue - Today's .357 Sig has more velocity than 1st gen loads ) . Back when .357 Sig was new , typical real world was 125 gr @ +\- 1250 fps ( multiple piblished chrono tests ) . In the same era , CorBon 115gr @ 1337 fps ( my chrono from G17 , but also multiple published chrono tests similar ) . Both had excellent terminal performance , both of them overlapping full power .357 Mag 125gr from 2.5 inch revolver .

I recall reading that the .357 Sig was supposed to go 1,350 FPS from a 4" semi auto, which equaled a .357 Mag from a 3" barrel, or in a 5" semi auto the .357 Sig matched the 4" .357 Mag loads. My guess is the hotter ammo was the advertised, but the low end is what was used and shot to 'fool' agencies into adopting it as 9mm recoil, .357 Mag power.

To me that says a lot. In the 'real world' I would say, in effect the .357 Sig and .40 S&W have more useable capacity. A 15 shot .357 Sig in the right hands could drop like 10 dudes - accounting for misses, adrenalin etc. The 9mm could probably drop like two due to how ineffective it seems to be. The ballistic one shot stop charts shows 9mm as good as everything else basically, but the footage I have seen would dispute those numbers.

People need to be more concerned about hitting their target than over penetration. I challenge anyone to annotate one civilian shooting where over penetration injured an innocent bystander. I’m glad you touched on how clear gel is not the same as 10% the FBI uses all compared to human tissue. As gel tests become the norm, it’s important for people not to get use to such tests and start correlating the results as results one may expect on the streets.

[@GunSam]

True. I think I heard of it where a cop did it, but not an ordinary person.

[@johnw4999]

@@GunSamand they are much more likely to be in confined areas w non-threat targets. Even taking LE in to consideration, how many over penetration reports are there where someone was inadvertently injured? I was a LEO for over ten years and haven’t heard of any - not that that means anything, lol. I’m sure the results would be so low that over penetration is almost a moot point… except for Air Marshals etc.

There is a similar group of people who claim the 10mm is as powerful as the .41 magnum. I know…right? Wanting to believe, is one thing, but refusing to believe is ridiculous.

[@GunSam]

I mostly hear people saying the 10mm is more powerful than the .44 Mag. When I address this as wrong, they then start talking available ft lbs that add up, 15 rounds of 10mm is 11,000 ft lbs of energy, 6 of .44 Mag is 5,000 ft lbs energy etc. I tell them, that's not how it works - because their example is like saying 15 bb gun bb's is the same as a single shot of .22 LR....They stop responding.

[@grizz474]

For self defense....a bad guy wouldn't know the difference between the two. There's a reason everybody carries a 9....more rounds, less recoil, cheaper to shoot, less report. Having said all that....the .357sig does kick ass!

[@カルロス山本-k8r]

357SIGは弾頭形状が悪かったから貫通しただけで、開きやすいホローポイント弾にすれば間違いなく停まるでしょう。 ただ拡張を遅らせるハイドラショック弾では、357SIGの速さだと貫通しないか不安です。 弾数の僅かな低下だけでマグナムオートが手に入る357SIGは素晴らしい！ しかし、「357SIGの圧力に耐えられる設計の同じ銃で」＋P＋を使えば銃の寿命にゆとりを持たせながら強装弾をバカスカ撃てるから、目的によっては＋P＋を選ぶ事も間違いではないかと思います。

[@libra7624]

another myth misunderstood by the gun communty is pain, books written about pain show that just because the wound is bigger it doesnt mean it hurts more because it depends on the nerves and also you got delayed pain that you dont feel sometimes when your in shock so a little more damage doesnt equate always to more pain like on a 1 - 10 chart because it depends on many factors, this is why guys can soak up anything unless blood pressure gets dropped or head shot, spine and such, damage certainly will stop someone but if that shot is in the right place. if you blow out the heart with a 9 mm or 357 sig i dont think there is much of a difference to mean much when a round with 10 - 20% less energy yields almost the same results, a 60 caliber hole in the heart or 70 caliber is still a big hole gushing out and like i said a non vital area it doesnt mean 10 - 20% more energy hurts more wich is a myth people used to equate more damage with more pain wich isnt always true due to many factors, you actually surviving being shot by a smaller caliber will feel more pain if nerve ending can still send messages to the brain where as a larger caliber may sever nerves giving it a numb feeling or a delayed pain that comes later when you get treated, its the same concept of breaking a leg and not feeling it at first and then stub picky toe on door and jump up and own right away feeling more pain immediately from smaller wound, so people think for example if you get hit in a non lethal area with a 9 mm and a 45 then the 45 you will feel more pain, not necessarily and we know guys perfectly sober and not on drugs can soak up a dozen 45 acp rounds if shot placement isnt correct like the cop in ohio massad ayoob interviewed who finally after all his duty issue 45 acp mags of his Glock 21 45 hit the perp with his last shots in heart and head wich is proof its all about shot placement since pain doesnt kick in even with a wide wound channel or the will of that person can ignore pain better, even a adrenaline dump in the body can offset pain

[@frawdulent]

The 9mm hitting the steel is just embarrassing. It’s barely scratching the paint. I don’t understand why the guntubers push it so much. I’ll stick with my 40sw and 10mm.

[@GunSam]

It's just that these are copper and they do not flatten on the steel, so they don't leave as big of marks.

[@marknorwood7521]

First off, I like Underwood a lot. Couple of questions, 1: Is that Xtreme "Defense" or "Penetrator"? 2: What kind of difference would the added velocity of the 68 gr (1800 fps) make in penetration? Also I realize many guns accept +P, no problem. I'm wondering how many are rated for +P+?

[@veroman007]

It’s just a matter of everyone has already bought a 9 mm and think it’s the best so whatever the results are you’re not going to convince them otherwise. Plus the ammo was cheaper and more abundant

[@GunSam]

Yes, exactly. Said guy buys a Taurus G2C (decent pistol not knocking it) and a box of target ammo, then researches what he bought and finds evidence he made the best choice, then starts getting into grey areas- urban legend type nonsense that it's just as powerful as .357 Magnum and the like. You can find exactly what you want to hear if you look long enough for it. They say Bigfoot chasers always find evidence of it's existence, because they were looking for what they thought correct evidence was.

@@GunSam the Budweiser of guns 😉

[@mesauer]

One observation. Look at the slow mo of the bullet impacts. The 357 sig has considerably more “temporary wound cavity”. This is a critical part of a bullets true stopping power. That temporary stretch is what shocks vital organs. A vital organ that is not directly impacted by the bullet can be “shut down” by the temporary wound cavity. I agree, significant difference between the two calibers!

[@mesauer]

The stretching of the tissue (temporary cavity) is the way you can “see” the pressure. We are saying the same thing.

[@rohawaha]

There is no such thing as over penetration , as you go up in bullet weight 9mm cases cannot hold enough powder to keep up with .357 Sig. I shoot 9mm Major or " Major Power Factor " at matches . I have driven 9mm 124 gr hp's to 1,425 fps to compete in that foot ponds energy class with Bryan Enos load data " and this is common " . I have been reloading over 45 years , back in the day .357 magnum was king . Why you ask ? Because back in the day police ballistics on shootings of all calibers were available and everyone wanted the caliber with the highest percentage of One Shot Stops . For Forty Years the King of One Shot Stops was a .357 magnum round with a 125 gr. bullet velocity 1,500 fps ! It was devastating on the human body. Well .357 Sig duplicates these exact ballistics with twice the capacity of a revolver, and that is why I owe several .357 Sig pistols.

[@kennethvansickle3707]

The 357 Sig was envisioned as a cartridge for pistols that approximates the power of the 125 gr 357 magnum, which it certainly does. Unfortunately the ammo is so expensive that it has not become a commercially viable round. Pushing a 9mm to attempt to attempt to duplicate the performance of the Sig will undoubtedly result in premature wear on the 9mm. Accept the 9mm as the preeminent defensive round which performs well with today's ammo. If you need more, then buy a 357 or the Sig.

[@jared8324]

In MAX available loads , 9mm < 357 sig < 357mag

[@mk45gunnr25]

actual terminal ballistic differences, as in wounding and mythical "stopping power" between handgun rounds is negligible. Carry whatever load that YOU shoot BEST. It's really that simple. Getting into these extra powder handgun (yes I said powder not power) does NOT ensure that you are carrying a magic "death-ray".

[@gloriamaletta8667]

357 SIG is more powerful than 9mm +P and 40SW but less powerful than 10mm 357SIG and 10mm are a joy to shoot out of a fullsize handgun fun powerful and as you go over 50 yards or more the 357 SIG and 10mm really shine in accuracy and power love both but it's a ammo price problem vs 9mm they are pretty expensive to shoot and practice with have a SIG P320 fullsize 4.7 barrel 40SW / 357 SIG combo and a Glock 21 Gen4 45ACP / 10mm 5.2 inch threaded barrel combo with 10mm and 45ACP magazines love both of these guns and do not want to sell them ever it's a expensive treat to shoot a 100 rounds of either 357 SIG or 10mm wish l had the cash to shoot them way more often generally shoot 9mm 22LR because of cost and even 9mm isn't that cheap to shoot if your popping 200+ rounds or more per range vist

[@jmd1743]

"Why would you buy 357 sig when you can buy bubba's pissing hot ammo?" Actually it comes down to practicality, if you're into 10mm then you might only have 357 sig as an option for a specific pistol due to frame size, some of those pistols are just a matter of swapping a 40 S&W barrel.

[@peelreg]

SIG should have named it the 9mm Magnum. Because that is what it really is.

[@GunSam]

Now days, yes if invented now maybe 9mm Magnum. But in 1994, cops were still transitioning from .357 Mag revolvers to semi autos, and none trusted any caliber other than their proven .357 Mag, so Sig named it .357 Sig to get the interest of law enforcement.

The difference is you can get 500 ft lbs from a plus p 9mm in a duty length gun, you can hit 700 with 357 Sig.Both those numbers would be light for caliber bullets in max loads.

[@GunSam]

147 gr is where .357 Sig can shine. With 147 gr 9mm, I typically see 300 ft lbs. With 147 +P+ I can see about 430 ft lbs energy. In .357 Sig 147 gr I see 540 ft lbs energy.

A Los Angeles County Deputy Sheriff shot a bad guy with his Beretta 92 9mm 147 grain hollowpoint killing the store employee after the bullet exited the bad guy shattered the store window and striking the poor innocent person. This was taught in firearms training what your Glock 19 service pistol can do. Bullets will have enough energy to kill after a through and through shot.

people say random statements but i think what most mean by saying hot 9 mm is as powerful as 357 sig is when comparing it to a few watered down 357 sig wich may be out there but certainly if 9 mm can be made hotter so can 357 sig and no doubt a 9 mm case will never be able to do that of a 357 sig
