26 Things People Didn’t Know About Bulletproof Vests

tags510 Disposable Cartridge

Bulletproof vest... This is something that police officers take for granted. The problem is that this helps save their lives. However, if more law enforcement agencies know about body armor, then they will not use body armor when performing their tasks.

The reality of bulletproof vests is that they are not bulletproof, in fact they are bulletproof. The reality is that bulletproof vests cannot protect the wearer from various threats. Nothing is bulletproof, not even a manhole cover. In rare cases, bullets can pass through vests designed to stop them. The bullet may have jagged edges or something similar. Bulletproof vests will not make the wearer a superman.

Body armor consists of very strong non-woven fabric and/or woven fabric

. The material will stop bullets, similar to how a net will stop tennis or volleyball. It causes the bullet to rotate, slow down and transfer energy through the entire panel. Bullet mushrooms, this helps in the process. Remember, the slower the bullet, the better the physical condition of the wearer. A hard tip or bullet fired at a high speed will pass through the fiber and directly through the bulletproof vest.

Many gun lovers ignore the lethal potential of certain pistol calibers. However, any bullet (regardless of size) traveling at high speed will pass through the body armor. Larger pistol bullets, such as .44 Magnum and .45 ACP, will travel at a slower speed, which allows the body armor to stop them. However, the .357 SIG and 9mm guns travel faster and cannot easily stop them.

The bullet of proof bullet gun is very dangerous for the wearer of bulletproof vest, because the vest is not suitable for such bullets. the reason? The speed of the cartridge case is inconsistent.

Most body armor in the United States has the standard five-year service level of the National Institute of Justice. When wearing a vest every day, it loses its protective ability faster than a vest sitting on a shelf. No matter how long the body armor is worn, the vest should be carefully inspected for signs of damage, including creases, tears, odors, and burns. If properly cared for, the vest should be used for five years. Make sure to follow the care instructions. Learn more about


Make sure the agent fills out the warranty card to register the vest. If they don't, make sure you do. The reason is, for example

Recall that many companies will find it difficult to get in touch with customers because they fail to send the warranty card back.

It is important that you have at least two carriers-one to wash and the other to wear. Keep it clean and dry to ensure that the bulletproof board can be used for a full five years.

When you need to clean the bulletproof board of the vest, please use a wet sponge and neutral soap. If needed, you can also use Febreeze on them. Do not throw them into the washing machine and/or dryer. Do not iron them either, because ironing will cause the fibers to burn or melt.

Don't forget that the bulletproof board is composed of several layers of bulletproof fibers. If they are bent or deformed, they cannot be straightened or ironed. Therefore, if you make a mess of the undershirt and vest, it will dry out.

Your worst idea is to put on your body armor and go swimming. The reason is that some bulletproof vests lose their ballistic performance due to water acting as a lubricant. When this happens, it can easily be penetrated by bullets. But remember... some

The vest treated with waterproof material can then be used in the water.

Most vest garments of US law enforcement agencies are similar to garments in manufacturing methods. They have pins, quilts and various other tricks. An experienced garment worker will check the bulletproof vest like the underwear you wear today. They are looking for any sewing defects that would cause the vest to be inefficient.

In many cases, officers

Wearing their body armor. Most of them equate the feeling of being hit by a bullet with the feeling of being hit by a hammer. The result of being hit by a bullet wearing a body armor is an unpleasant-looking bruise, which is caused by the deformation of the back.

So far, no one has been killed as a result, and it is unlikely that the wearer will be incapacitated. Many law enforcement officers hit by the armor responded, trying to eliminate the threat. Moreover, this was adopted even before the latest vest materials were used, and the latest vest materials were designed to reduce the impact of blunt objects.

When the bulletproof board sags, the bulletproof vest is uncomfortable to wear. Worst of all, it does not provide the protection the wearer wants or needs. The solution to the problem is to rotate the carriage. Most bulletproof vests are sold with several carriers, although it is best to have three. When the bracket is rotated, it can prevent the Velcro straps from being worn and stop the wear of the fabric.

It is important that the body armor wearer's body weight cannot exceed 10%. If a person gains 5% to 10% weight after installing the vest, they need a new weight. If a person loses weight, they may also need to install a new vest.

No law enforcement personnel should wear vehicles to avoid being injured by bullets. After all, it does not provide any ballistic protection; it is like wearing a T-shirt.

Bulletproof panels have been created to fit the carrier in some way. If the wearer mistakenly believes that they will lead to tragic consequences. The striking surface of the panel slows down and disperses the energy of the bullet. The back of the panel can reduce trauma. If the panel is flipped, the vest cannot stop bullets.

Wearers of bulletproof vests need to understand that bulletproof vests are not knife-resistant vests. The stab-resistant vest is made of another fiber and braid made of bullet-resistant vests. There are multiple threat vests on the market. However, these are usually heavier and more costly.

Every year, during the International Association of Chiefs of Police, DuPont will hold a ceremony to commemorate the officers rescued by the police.

Body protection. After the accident, many police officers recognized at the award ceremony not only got out of the bullet, but were also saved from the impact of the steering column of the patrol car.

Body armor is not a high-tech body armor/running suit. When a person wears a vest, they need to breathe deeply. This is the desired gap between the body and the armor plate. If you encounter a bullet, the gap will help reduce trauma. This also makes it easier for officers to run and fight. In short, the function of the bulletproof vest is better when moving. Need to tighten the belt and feel the tension. Many newcomers try to fasten their vests like corsets or corsets. However, doing so will make them feel compelled to walk after someone sitting on their chests.

Many officials will use tape to fasten the vest to their body. However, this is not a good idea for many reasons. One of the reasons is that duct tape will tape the vest, so it cannot move with the body correctly. And, this means that coverage issues may occur during ballistic events. The second reason is that duct tape does not provide additional ballistic protection.

It is important to understand that once a law enforcement officer is shot while wearing a bulletproof vest, he/she needs to get a new one. After all, the fiber has been damaged by the bullet and cannot be repaired.

It doesn't matter when of the year, law enforcement officers must use both the front and rear panels to protect themselves. Many times, many police officers will only use their front panels in summer. The thugs don't care if it's summer or summer. If they can shoot an official, they will do everything possible...including on the official's back.

Many police officers like the back pocket in their carrying bag with trauma pads. Police often put spare holsters or mobile phones in them. Don't do that! According to the design purpose, it is used for trauma pads. If the wearer's vest is hit, the trauma pad will reduce the occurrence of bruising.

In many cases, law enforcement officers who work on the public line do not have their duties.

in. Instead, they refused to wear it and left the vest in their locker or suitcase. It is essential that all law enforcement agencies must always use bulletproof vests!

Women must provide additional trauma protection for their chests. For this reason, their vests should be equipped with real bra-style cups, similar to the cups on a one-piece swimsuit.

In the United States, most bulletproof vests issued to law enforcement agencies have a 5-year warranty, namely

. This is the time your body armor can maintain its level. The true rating of your vest and the degree of protection it actually provides is affected by the frequency of use. If you wear it every day at work, its "wear and tear" will be much more than when you use it only occasionally, which will weaken it.

After several years of possession, the bulletproof plate of the vest should be checked. Look for any damage, such as tears, creases, burns, or even a suspicious smell. Follow the instructions on how to maintain ballistic armor, it should last longer.

According to stubborn rumors throughout the police world,

Before certifying the vest, strengthen the NIJ shooting position. However, the test protocol does not allow

 The manufacturer can do this.

As you can see, you don’t know much

You can also see why every law enforcement officer in the country and the world must use bulletproof vests, which is crucial. Put on your clothes today and you can go home tonight!

If you have any comments or questions, please do not hesitate to leave a message in the "Comments" section at the bottom of this page.

If you are shot while wearing a vest or your partner is shot, please go to the emergency room to check whether the blunt instrument has been injured by external force. Bring the vest to the hospital (with or without evidence) to ensure that the doctor can determine the type of potential damage to bones, organs, and tissues.

My good friend G Lang is a very qualified ballistics analyst. He said that whenever you are hit by a bulletproof vest, your ribs will crack. Every. single. time.

It depends on where you are.

At least you are not dead! =)

It's not correct at all. I have been shot twice, and I have not dealt with a broken rib twice.

Is it impossible to use trauma pads to reduce back deformation and potential trauma?

Yes, it is possible. good idea!

Mom, why are you angry?

You made a basic mistake in section 2 where it states: "Remember, the heavier and slower the bullet, the better the wearer's body will be."-This is incorrect, the two bullets are at the same speed Spread, but with different weights, heavier bullets will have more energy and therefore greater armor-piercing capabilities. Of course, other factors also play a role, including the cross-sectional area of ​​the bullet.

Thank you for your comment!

To avoid any misunderstandings, we have deleted the "heavier" part.

What we want to explain is that small and very fast ammunition (such as FN 5.7×28mm) may be more dangerous than slow and fat ammunition (.44 Magnum) because they are more likely to penetrate the vest.

I have no shooting experience with or without a vest, but my best guess is that if someone is hit by a .44 Mag FMJ, then they are likely to stop because of penetrating power or blunt force Trama. Suffer serious injury or death. heart. I do not agree with the statement that the vest is more likely to block the .44 Mag position than the .357 Sig.

If the 0.44 magnum penetrates the vest, it may be fatal, but if the armor blocks the bullet, there is almost no chance of causing life-threatening damage. If it is blocked by enough body armor (such as level III or higher body armor), even a rifle bullet (energy is twice or three times the energy of a .44 magnum) will not cause fatal injuries. Of course, there may be huge bruises, broken ribs, etc., but with proper medical care, there is almost no life-threatening risk. Now, if you are talking about .50 BMG, then you might encounter a situation like this ?

Certain speeds can indeed penetrate certain rated armor, but heavier shells will cause more blunt external force damage. The greater the mass of a round, the more blunt the force. Especially if it moves as fast as .44 mag. The .44 magnet moves at a speed similar to 9mm + P, pushing the bullet into a position that is 2 to 4 times heavier. 240 gn .44 mag will run at 1300-1500 fps. The 9mm + P 114 gn bullet can only propel 1300-1400 ish fps, while the non-+P is subsonic and moves at 1050 to 1200 fps.

Therefore, no, any 9mm armor will not threaten any level of body armor, even the old IIa armor. A .44 mag can penetrate almost all soft armor 10 years or earlier. Until recently, soft armor was rated as capable of blocking 0.44 pounds of ammunition. However, most modern soft armor levels cannot stop .454 cas, .500 magnum or similar ammunition.

The 5.7×28mm is more like a rifle than a rifle, although it is mainly fired from a pistol. It will run at approximately 2,000 fps, so it has a reputation for wearing body armor. This is a rather weak round, and the penetration power after passing through the soft armor is questionable. TBH If I have to be hit by something, I think I would rather be hit by a 5.7×28 and suffer a small minor injury, rather than dealing with a blunt force of .44 mag. Neither will be very interesting, and even armor can kill you, but I think .44 mag is more likely to kill you than 5.7.

Rifle shells can penetrate soft armor without any problems. From the pistol configuration, you can easily trigger a .300 blackout, 7.62×39 or .223. The speed of these shells is sufficient to prevent the soft armor from providing too much protection. It's better than nothing, but not so much.

Generally speaking, no author is correct. You want to add the third part of energy, and blindly assume that heavier bullets travel slower and will have more energy simply because they are heavier. Even when loaded to the same chamber pressure. This is not always true, and even true in most cases. As we all know, in a given bullet structure, the impact velocity is the most decisive factor for armor penetration. In addition, many bullets of the same caliber are lighter than the heavier brothers. In addition, the load is developed for the sub-elastic energy rather than the maximum velocity of the stator bomb. They may also change the bullet structure or a combination of the two. Focusing on pistol ammunition rarely means more energy.

Let us look at one extreme, and then another extreme. We can use the luckygunner test results because they are all done using the same gun and test protocol.

The first is the heavier weight, which is considered to be one of the best loads of 9mm. All data comes from a 3.5-inch barrel:

Federal 147gr HST + p load @ 1008 fps.

Liberty 50gr civil defense + p load @ 2034fps.

Therefore, we have two loads in the same general pressure range of +p, one load is almost 3 times heavier, and the other load is only 3 grs shorter. Use the formula energy = bullet weight x speed ^ 2 / 450,437 to calculate the ftlb of energy (bullet energy (in pounds) is equal to bullet weight (in grains) multiplied by the square of bullet speed (in per foot) minutes) Divide by 450,437).

Federal 147 gr HST + p @ 1008fps = 332ft/lb

Free 50gr civil defense + p load @ 2034fps = 459ft/lb

Therefore, we can see that it is not close yet. The reason for this is that the bullet becomes heavier and heavier with a given stator bullet caliber of a given structure, and it must become longer. Longer bullets have a larger surface area along the body, so the friction of the barrel is greater, and there are other factors that also affect the weight gain. This is not a strange comparison, even if we can see other products in the same product manufacturer and ammunition production line.

Compared with the lighter 124 gr + p brother, bear the same heavy load

Federal 147 gr HST + p @ 1008fps = 332ft/lb

Federal 124 gr HST + p @ 1168fps = 375ft/lb

It can be seen that even if the same bullet design is used, it can withstand the general pressure from the same pistol, and the faster bullet has more energy.

Now you can use the cross-sectional density as a key indicator of bullet penetration depth and energy. In fact, for today's FMJ of the same caliber constructed with high-tech bullets, the bullet you have has higher energy penetration, while other bullets have less penetration. Approximately 115 mm is deeper than 147 grams.

The fact is that for a given bullet diameter and frontal cross-sectional area (the surface area of ​​the bullet nose), the speed of a bullet is the difference between whether a bullet penetrates a given ballistic protection level.

By the way, the civil defense load of 50 grams has penetrated, that is, it has defeated the IIa, II, soft and even IIIA ratings targeted by its test. It is actually a very fragile bullet structure that breaks almost immediately after penetration, and usually does not exceed a pen depth of 12 inches in a calibrated ammunition gel

Of course, now, if you use the same bullet of the same design and run the heavier bullet very close to the exact same serration, yes, it will penetrate at the serration with the lower serration. However, it accounts for almost no percentage of weight difference. Now, it has well shown that heavier bullets of the same caliber and bullets do not mean higher muzzle energy. A common confusion is when you try to transfer the long-range impact energy of a high-power rifle bullet to a pistol. In the rifle, the retained energy is also a factor of the ballistic coefficient, or more accurately, the drag co curve. Hornady's paper is excellent. This is why generally speaking, for a given bullet design, the farther you want to hit the target, heavier bullets usually have a higher BC or better resistance curve and therefore will not maintain longer energy. So as to have more retained energy. However, when both are loaded to the same psi, pay attention to the bullet energy at the muzzle.

This is a very close example, because I want to try to find a comparison that is more favorable for heavier bullets, because both of them are close to the same bearing surface area due to structural differences, and lighter bullets are used when approaching vel When it exceeds 3000 fps, with the increase of the vel bracket, the vel efficiency obtained by the same powder pressure increase becomes higher and higher. But even here, the lighter bullet wins, or for practical purposes, it is the same in this case. But of course only 100 yards away, the higher BC 165gr will take off from the lightweight BC bullet. We don’t have these problems to deal with SD pistol range and bullets. These distances and distances are measured in feet instead of yards, even at distances in two-digit feet. Nowadays, rifles use three-digit numbers or more. The distance is measured.

308 Win Barnes loading data

110 TTSX max vel 3539 fps 3054 ft/lb

165 TTSX maximum speed 2877 fps 3033 ft/lb

If you look at the new 07 NIJ standard, you will find that they use a lighter 124 gr signal for signal transmission, as well as wheels with a smaller nose cross-sectional area and other bullets that are not heavy in bullets, and due to speed reasons This speed is the enemy of bullet-proof penetrating ability. If you want to do it yourself, you can work in science and physics, because not only does it require a post to explain everything, but my post here is already annoyingly long.

Therefore, according to everyone's rough statement, the equal speed of everything determines the penetration or failure of ballistic armor.

This is a great article. It has received an unethical evaluation. It may be the most thorough and convincing article I have read on the Internet.

Obviously, you know the subject well.

Whether ordinary civilians are allowed to use bulletproof vests in the United States (because hate crimes increase hate crimes to some extent, other nationals may be shot in the wrong identity) to protect themselves from crazy shooters. If possible, you can buy and Use bulletproof vests to use them correctly?

It violates the purpose of civilians wearing body armor. It can only be worn by police, medical staff, security personnel or other officials working in high-risk emergency situations.

Defeat the purpose? The purpose is to survive. Why must it be an "official"... and answer Sathya, yes, they can buy it.

Completely agree with your comment!

How to defeat the purpose of the vest? It aims to protect the people, and the civilians are the people.

The police (as well as paramedics and security services) are civilians.

Unless you are a soldier, you are a civilian!

So in the movie, when the vest is hit, they will take off. Wouldn't it be better even to be hit in a shootout?

Yes, that is correct. A vest has been tested to withstand multiple shocks. Although the location where the bullet hits the vest can be considered a weak point.

Can the lvl iv vest stop bullets within the scope of the 9l lvl II vest, right?

Yes, that is correct.

Where can I buy women's vests?

A good place where one is

Great website. I like reading very much.

I have a vest that used to be my father, how long they can usually live. I have been there for more than ten years?

If you use 150 lead or lighter lead instead of 200 or 250 pellets and a certain amount of powder to pack 44 high-capacity bullets, it will pass through the bulletproof vest

Reloader, your statement is correct in principle, but it is not. Not all vests are created equal, and my lighter .44 Mag may penetrate some vests, but this is not a guarantee, it will not be punched with steel plate for example through AR500's $300 vest.

Thanks for this very informative and interesting article. I just want to know if there are any side panels to protect the sides of the ribs?

Is there a lightweight bulletproof vest specially designed for women? I saw a 1.3-pound white on the line, I believe it is a trademark called Ghost, and I can’t find it now. Are you familiar with this? thank you.

The bullet of proof bullet gun is very dangerous for the wearer of bulletproof vest, because the vest is not suitable for such bullets. the reason? The speed of the cartridge case is inconsistent.

Pass this sentence to anyone who is a gun expert for correction.

.44 Magnum travels at a speed of nearly 1,500 feet per second. This is faster than 9mm and most other pistol cartridges. This is about twice that of .45 Auto, and there is really no basis for comparison between these two rounds. Your basic premise is correct, because speed is the main factor in beating the vest, but your example is terrible. I would also like to see one of these jagged edge bullets you mentioned. The hollow point has this appearance, but is the furthest away from the armor piercing.

Exactly. In which world does the author live in the "slow" place of .44 Magnum? The .45 Auto can be said to be slow and fat, but the .44 Magnum is fast and fat. Compared to almost any other pistol caliber, it is more threatening to penetrate body armor (especially with hard cast bullets).

If an FBI bulletproof vest is used to fire a bullet gun (ROYAL REMINGTON 870 EXPRESS BREACHING SHOTGUN, to be precise) at someone at a distance of about 1.5 meters (59.0551 inches), can the vest be pierced? If not, considering the distance of the shotgun’s explosion, how severe is the impact on the impact?

If your vest gets wet, really wet, can you dry it, will it still work?

Hello, Michael: If the panels are covered by a waterproof jacket, you can still use them. Today, almost all panels are covered by waterproof envelopes. Scott, greetings

Thank you for helping me learn more about bulletproof vests. I don't actually know that the ballistic board should be placed in the vehicle in some way. Knowing the appearance of each side sounds important so you can distinguish between the two.

In fact, some body armors are effective for small bullets, some are effective for armor-piercing bullets, and are effective for large bullets. Some target dozens of types. Special body armor has been specially tested to resist these threats that should be defended, and the best way to understand it is to pass the test results. Although storage, temperature, humidity, etc. may be important, this is part of the test.

In some cases, certain types of body armor will withstand the strength of certain bullets 100% of the time by stopping bullets and ensuring a safe amount of back deformation. In some cases, others will be organic and will never be effective against certain types.

Generally speaking, the most important factor in the effectiveness of body armor is to know the bullets that will hit you in your situation. Sometimes, from the police to the military, if too much information is provided, the Android shooter will adapt to the body armor, and the performance of the body armor may change the worst. Therefore, the bodybuilding armor is effective only after the shooter finds the appropriate gun, bullet and shooting position. Some armor piercing can break through. Sometimes, bigger rounds. Sometimes smaller rounds. It depends on the armor. However, in general, the greater the power, the smaller the range, the better, and the closer the shooter, the less likely to be armored.

Is there a bulletproof vest for sale on Amazon? This seems to be a difference of opinion.

When storing vests, where is the best place to store them?

Hi Ralph,

Place it flat on a shelf and place it at normal room temperature. Not in the sun.



It depends on the laws of your state, for example, it is illegal to own body armor in Connecticut.

However, you can buy body armor in many places. But keep in mind that lighter vests (Kevlar/ceramic) are less durable than heavier vests (coated steel), and will have fewer hair loops and smaller calibers. For example, the price of steel plate on AR500.com is very cheap (the price of a steel plate vest is several hundred dollars), but the weight is very large. At the same time, other sites such as Safelite Defense are more portable, but cost more.

Mistake: The sale of body armor is legal in all 50 states in the United States. However, Connecticut only allows face-to-face sales. In other words, you must go to the store or reseller to buy in person; you may not do this through an online supplier.

I may be a little late on this topic, but I cringe a little at the term "bullet-proof vest". Don't want to be picky here, but you solved the problem in your first project, but still call it "bullet proof" in the rest of this article?

Ballistics and ballistics are basically the same. The term "bullet-proof vest" is incorrect, and this is still a stubborn myth. Same as "waterproof jacket". The proof here may also mean "resist."

What purpose did it fail? ? ? If I live in a poor, dangerous area, with crime-ridden, gangs, and you have a vest, then say "put it on!"!

I didn't realize that you have to breathe deeply to get used to lol! Learn new knowledge every day.

"Huge pistol rounds such as .44 Magnum and .45 ACP will travel at a slower speed"

Do not. This may be correct for a .45 ACP wheel that is more than 100 years old, but the .44 Magnum usually moves at a speed of 1300-1400 + fps, which is equivalent to 9mm.

Perhaps the author is thinking of a special value of .44, which is an older, slower low-pressure range.
