Why would he use +P ammo in .45 when he didn't mention using +P in any of the others??? You sound like exactly the type of guy you are accusing him of being, except you have .45 tattooed on your ass, and seem butt hurt because whatever caliber YOU invested in (financially and apparently emotionally) did not appear to perform well in this unscientific and rather pointless comparison. Frankly unless he is testing specifically for aluminum barrier penetration, this review doesn't prove much of anything. Even if he was testing specifically for aluminum barrier penetration, he would need to do an even comparison of several shots from each weight of each caliber to gather any meaningful data to draw conclusions from. I wasn't going to comment at all except you seemed like a dipshit who is oblivious that you are projecting your own weird childish hangups on another poster.

[@johnmatthes8608]

Secret service uses this caliber for a reason! The best performing semi-auto caliber period. They want a bullet that STOPS THE THREAT NOW! Not minutes later from blood loss (black Talon) but NOW. Unfortunately too many in the industry include deaths by blood loss in how "effective" a defensive round is but that bad guy who died an hour later in the hospital can still kill dozens until they drop. Effective bullets stop threats IMMEDIATELY as possible. For some reason the high velocity 357 mag (revolver) and 357 sig (semi auto) do this more often than the other competitors. I want those that write articles about "one stop shot" percentages to NOT include subjects as a successful stop unless they went down immediately. That's real world!

Also to remember the 9 is to produce casualties, 45 to stop inside the cavity, the 40 to hit harder than the 9, stop in body cavity and the 357 sig designed to penetrate barriers, produced casualties and achieve characteristics similar to the motherland round .357 magnum

40 was disadvantaged. 165 is the nominal weight, 180 is heavy. I would expect the 165 to perform similarly to the 357sig.

[@camaro25]

This. Every single test I see like this when people test out 40 S&W, they always use 180gr rounds for some reason. The most common rounds carried in 40, especially for defensive loads are either 155 or 165 loadings. Those can get up to and sometimes over 1200fps. I want to see one of these tests where they don't use slow 180gr range ammo. I don't think it'll do as well as the 357 Sig, but it'll do better than the slow 180gr rounds.

[@christopherarnett2851]

As to the .40 cal - 10 mm argument the best description I can remember is to think of the 10 mm as a .40 magnum since the difference is 10 mm is longer so it holds more powder.

Francis Allen this is true but it doesn't take into account that not everyone involved in a shootout will stand out in the open. They will hide behind things like cars.

[@watcher01a17]

Francis Allen That is totally untrue. The .40 smith and wesson was ''designed'' to reduce the amount of recoil of the 10mm. Because too many agents were having trouble qualifying, due to the recoil of the 10mm. So the .40 was just a compromise. It offers adequate tissue disruption, penetration, and barrier resistance, while having manageable recoil. But it was not ''designed'' for anything other than less recoil than a 10mm.

10mm can push heavier bullets faster than .40 due to the longer case. In range ammo, 10mm power is about the same as .40, but self defense and hunting ammo are much hotter. That being said, 9mm is perfectly acceptable for self defense with modern expanding bonded jacket bullets. It's cheaper to practice with and follow-up shots are going to be faster. And you get more shots in your magazine if you live in a free state that doesn't nerf the standard-sized magazines. Since I live in Communist-ruled California, I like .40, .45, and 10mm since I am limited to 10 round magazines.

[@SuspiciousGanymede]

John Shalamskas doubletap and winchester make the strongest 40 ammo (ranger t's) theyre loaded like a 357 fmj. the doubletap are jacketed cast lead HPs. shot a hog in the head with the 200gr version it was sticking out the backside of the skull. cant say the same from my 135gr fmj 357 that bounced off the same area different hog

[@WI7262]

Great penetration test! thank you. I just wonder how this relates to the stopping power? For example, will the slower and less penetrating .45 be more destructive than the more penetrating 9mm and .357sig? Conventional wisdom says yes of course. In gel tests the internal destruction of .45 is scary.

My uncle is a retired police officer and carries a 45 for the stopping power it has. For me is to heavy. But I liked to have more stopping power than the 9 and no over penatration like the 357 is why I have 40. I tested the 40 and 9 on a 2x4 wood board and the 40 did better. You can say what ever you like but I will Stay with my 40

[@ThePenetrationChannel]

I didn't say anything. I simply performed a test, and shared the results. Thanks for watching.

[@acoupleofthree3556]

@william terry a myth? So you're saying a high velocity round is equal to a heavier round? One goes clean through as he keeps coming or falls forward. The other breaks bone and pushes him back.

[@fnkdtnk]

Just Be You are you saying a 9mm that hits bones won’t break them, and a .45 will not only stop someone’s forward momentum, but will actually push them back? There is no semi auto handgun cartridge that will stop someone’s forward momentum. 300 win mag won’t even stop your forward momentum, much less push you back. Stopping power, as in it hits with enough force to change your momentum is a myth. Stopping power as in, it has enough energy to reliably kill your target instantly with a center mass hit is not a myth, but no semi auto pistol cartridge will do that with energy alone, you have to hit the spine, which means you need enough penetration to get the bullet into/thru the spine. A real world example to consider. East Texas deer are pathetic, 100 lbs is a good east Texas whitetail. 100 lbs east Texas whitetail don’t take a step or two back even when you hit them with 165 grain 30-06 ballistic tips. That round is carrying 4-6 time more energy than .45 acp, and most men are pushing 200 lbs. If a 30-06 can’t push a 100 lb deer around, a .45 acp certainly isn’t going to push a 200 lb man around

[@grady7443]

This test verifies 357sig is superior, penetrating aluminum. I'm pretty sure it is also superior penetrating humans. No matter how heavy their clothes are. Have been considering a g19 for a while now and about a month ago started considering a g 32. I would feel well armed with both but maybe better armed with the 357sig.

[@ThePenetrationChannel]

grady jr you would be good to go with either of these calibers. The 357 is my favorite of these four. thanks for watching.

[@cainammons896]

The Penetration Channel nobody worried about over penetrating? I carry a G32 right now and and considering switching.

[@ThePenetrationChannel]

Cain Ammons this test is a demonstration of the penetration capabilities of these calibers. I used fmj ammo to show this. you really don't have to worry much about over penetration when using self defense ammo (hollowpoints).

[@zowerr9139]

You’d get to practice more with the glock 19 since 9mm ammo is much cheaper than 357 sig. the more practice the better your aim and that’s often the deciding factor in a life or death situation, who has the better aim not the bigger cartridge. Also 9mm pistols have a larger capacity than the 357 sig.

[@longshot7590]

Shooting more is always a valid argument. However, that has a lot more to it then just ammo cost. Argument of "holds more ammo" is negated by your argument for better marksmanship thru more practice! The difference between 17 rounds and 15 rounds if nil. The difference between a 357 and 9 mm round is MUCH more of the "winning factor" then 2 extra rounds! Ditched my EDC G19 for the G32 because if every shot counts the best caliber is obvious. Try one and move up to the front seat of the bus - better view from up here :- )

[@floridahuntsman7915]

I had no idea the 357 Sig was such penetrating round. Great set up.

[@michaelnesmith7069]

Excellent video! Keep up the good work!

[@AkiraNakamoto]

Metal is ductile and sticky. The stickiness is proportional to the mass of metal that is broken/separated. The reason why .40 and .45 penetrate less metal is that they need to piece through more metal circumference and mass! 9mm and .357 only piece through 90% line length (80% mass) of .40 goes through, and .40 only pieces through 90% line length (80% mass) of .45 pieces through. In other words, .357 only needs to tear down 90% of metal molecular binding force from each metal plate (you may translate the circle to a straight line, .357 needs to divide a metal plate that is 90% in length compared to .40). In addition, .357 only needs to push 80% mass ahead compared to .40. These factors contribute to its penetration depth but not the energy measured in ft-lbs. Finally, .357sig has larger energy measured in ft-lbs. Here is a quote, in all cases .357 sig has larger ft-lbs than .40sw: At 125 grains, the .40 S&W maxes at about 469 ft/lbs compared with 564 ft/lbs for the .357 sig At 180 grains, the .40 S&W maxes at about 520 ft/lbs compared with 524 ft/lbs for the .357 sig At 140 grains, the .40 S&W maxes at about 415 ft/lbs compared with 568 ft/lbs for the .357 sig

[@henricvs]

Excellent content. Well done, bravo! I would love to see a similar test with the blowback calibers. I am a .32 ACP fanboy and would love to see how it compares to the .25, .380 and even 9mm in a similar test.

[@anthonyalise8254]

Biggest take away here for me is that the .40 and .45 transfer a higher percentage of their energy into their intended target. The smaller two 9mm's will over penetrate a soft target but hit a target behind a car door or some intermediate barrier icluding layers of clothing. Interesting data.

Shoulve used 185 in the .45, also. He used the lightest round on 9mm, but heaviest on the higher calibers. Still a great test, though. I know a lot of people hate on the .40, but i really like it, same terminal ballistics as a .45, with twice the kick, haha.

[@jeramyw]

@@the.living.man. I like a .45. But many factors go into the "perfect" bullet. I like .40 because of it's superior capacity over the .45 and it's more powerful than a 9mm. I also like the .40's penetration capability. But I ain't no expert.

[@the.living.man.]

@@jeramyw yeah, same, although with the .40, follow up shots are not as fast aswith the 9mm, my USP .40 kicks harder than my USP.45, and can only carry one more round, so with that particular setup, i favor the .45. But my P30 .40 carries the same astheUSP and conceals pretty decent, so i like a .40 there, whereas stopping power is still important, in my opinion. Nothing wrong with a 9mm, just too many videos of people fighting through it for me to be comfortable with. A great defensive caliber should not penetrate 2 .25" pieces of aluminum separated by an 1.5" spacing. You want to get into the thorastic cavity, and deal and create a shockwave, not pierce through with ultimate penetration, unless its a rifle round designed to yaw and tumble, like a 5.56. Yet, all the keyboard warriors undoubtedly look at this and think a .357 sig is superior. .40 concealed, .45 open/service, 5.56 truck gun. Sorry for the book, i agree with you completely.

[@jeramyw]

@@the.living.man. 9mm is ultimately tamer on recoil, yes. However with proper training you can speed it up. .40 S&W 165 grain HST does like going through things like walls, cars, windshields, and so on. 357 Sig is interesting. Although, .40 caliber projectiles can be used in .40 S&W, 10mm Auto, 10mm Magnum, and 38-40 WCF. That last one was a cowboy round made in the 1870s. It was the second most common lever action and revolver combo round back then behind 44-40 WCF. .45 Colt had a wimpy rim so lever action extractors couldn't grab initially. A Ruger GP100 Lipseys model would be a superb host for all those 40 calibers. Yugo M67 7.62x39 yaws as well. I wish to find a modern non corrosive substitute that's not so expensive.

i wounder how the fn 5.7 would stack up its got the speed. thank you for that test! most informative

[@thatsmytwocents4372]

Tim Beatty Would depend on the grain, which I believe is usually a 55 grain. The velocity will be high, but the light grain will work against it's penetration. Recall the grains used: 115 for 9, 125 for 357, 180 for 40 and 230 for 45. This being said, it may have the highest velocity being so light but the for pounds of stopping per will be light. Put it in comparison, it is less than half the weight of the 9. My experience leads me to believe it would be stopped by the 2nd panel. Hope that helps.

[@Ragnar_Helsson]

@@thatsmytwocents4372 think about what a .223 round would do to these panels. the FN 5.7 may only be 55 grains but its moving WAY faster. I would bet that it would go through at least 4-5 panels.
