Alot of manufactors claim there vest to be the best on the market.
With various standarisations such, NIJ, RPS, K, and others..

Level IIA,
Level II
Level IIIA
Level III

and more..

The majority of the vest in IIIA are to belived to be fully protectable against all 9mm rounds...

Well for thouse of you that havent been aware of the Swedish 39B 9mm round, heres the scary information.

This round is known publicly as COPKILLER Bullet in USA.

It was made and introduced 1939 and manufactured in Sweden for the Swedish military and the K-pist (automatic carbine)
Picture enclosed, aswell as picture of the round and penetration test in 10mm steel plate..!!!

A huge investigation was carried out in Sweden by the police last summer/autumn due to a police man was shoot dead in Sweden.
They discovered he was shoot 7 times, and he had a bodyarmor with plate..

After test shooting they found out that their isent a single Bodyarmor in IIIA that can take this round without extra protection (Plates)...the bullet went straight thrue both panels YES In front and Back panel!!!

This round is now forbidden, but many, many is out there specially since alot of the special forces around the world have used it in the present..

So, think twice if your safe...?
If a 9mm vest can go right true panels and plates...how safe are we?

On our advance tactical firearms course, together with shooting club/Police we can show and test shoot this round..(just to feel the driffrence and discover the incredable force it has...)

If anyone is interested to hear more about this 39B (bertil) round just ask or pm me..

Regards,
Hawk

HALO61

The NIJ Standard is just that a Standard were non-existed before. The NIJ level IIIA armour is tested against 2 types of ammunition;
The armour protects against 9 mm Full Metal Jacketed Round Nose (FMJ RN) bullets, with nominal masses of 8.0 g (124 gr) impacting at a minimum velocity of 427 m/s (1400 ft/s) or less, and 44 Magnum Semi Jacketed Hollow Point (SJHP) bullets, with nominal masses of 15.6 g (240 gr) impacting at a minimum velocity of 427 m/s (1400 ft/s) or less. It also provides protection against most handgun threats, as well as the threats mentioned in sections Type I, IIA and II. Any ammunition outside of that is pot luck, unless you check with the manufacturer to see if they have conducted any additional independent testing, and don’t be afraid to ask. If they are open and up front about their product they should tell you and provide documentation to support the testing. I know of at least one company that used to do that.

Stay Safe

Soft Body Armour ballistic material;
Woven or non-woven materials (Laminated).

The fibres used for modern ballistic resistant material are
Kevlar®, made by DuPont.
Spectra/Gold flex® made by Honeywell.
Artec® made by Artec.
Twaron® made by Teijin Ltd.
Dyneema® made by DSM.
Zylon® made by Toyobo. (Currently not recommended by NIJ)

Hard Armour plates can are made from a number of materials:
Metal, ceramics and other composite materials.

Aramid Fibres; Kevlar and Twaron

What is Aramid FibreA strong, heat-resistant fibre used in materials for bullet-resistant vests.

From Hexcel
The largest weaver of Aramid and other high performance yarns in the U.S. The Hexcel, Anderson S.C. plant has over 25 years of experience weaving high performance yarns. Our ballistic protection customers manufacture civilian and military body armor using Hexcel fabrics woven from Kevlar®, Spectra®, Twaron® and other high performance brand fibers. These cutting-edge performance fabrics offer unmatched resistance to bullets, frags, cuts, stabs and abrasions, while offering lightweight strength and comfort.

Twaron® fabrics by Teijin
5 times stronger than steel, in the last 10 years of Twaron® Developments of finer filament count, uniquely combined with higher tensile properties, resulting in the patented Twaron®- Microfilament, led to the newest types of Twaron®, exceptionally well adapted to the specific demands of ballistic applications both hard and soft; characteristics include good dimensional stability and high modulus; it does not corrode or wear.It is a safer, more efficient, cleaner, and ultimately, more cost effective manufacturing operation. One that requires less energy and raw materials, and produces fewer harmful emissions. The product last longer, and have greater added value and are environmentally friendly. Replacing traditional materials with new, improved, product Twaron is cutting waste,

Kevlar® by Du Pont
Kevlar is lighter and stronger than steel, but loses its desirable properties when exposed to the sun for extended periods of time. A tough yarn, suited for ballistic protection and is used both in soft body armor applications such as personal protection ballistic vest.


Trauma Plates/Panel
Trauma Plates are devices that when added to body armour over a localized area (Commonly the mass centre of the Torso approx 5”x8”) it increases the wearer’s protection against blunt trauma injuries. Soft or hard are available, I personally avoid hard as they increase the potential of a upward deflection/ricochet from the Trauma Plate/Panel, giving you an additional hole in the chin, which is a bad thing…

NIJ Edge Weapon/Stab/Shank Resistant Protection Standard
NIJ 0115 Sept 2000

Class 1: What might be expected on the street.

Class 2: What might be expected in a corrections environment.
(Referred to as the “Spike” Class)

Within each Protection Classes there are 3 Protection Levels.
These levels indicate the Stab energy (Joules).

What are joules of energy translated into English?


20 Joules
This level of indicated Stab energy is equivalent to;
6’ 1” Human weighing 200lbs with an over hand strike.

Protection Level Class 1 Class 2
(Street) (Corrections)
One 24Joules. 36Joules.
Two 33Joules. 50Joules.
Three 43Joules. 65Joules.




NIJ Edge Weapon/Stab/Shank Resistant Testing Protocol

Testing involves dropping a predetermined weighted blade / spike of 2.7 lbs (1.2kg) from calculated height on to the armour test panel.

The backing material for this armour stab block is:

4 layers of Neoprene Sponge
1 polyethylene foam
2 layers of rubber

Note:
Class 1 testing allows up to 7mm of penetration.
Class 2 testing allows up to 20mm of penetration.


Purchasing Body Armour
When looking at purchasing Body Armour consider it, the same as purchasing a car, look at its this way, your needs and performance (Reliability and comfort) these are some of the basic things, remembering the idea of wearing Body Armour is to end your duty shift with the same number of bodily holes you started the shift with, any additions is a bad thing!

What is the threat level priority?
a. Ballistic Caliber
b. Edge Weapons
c. Or Both

Ballistic Threat: Does the armour stop the ammunition you carry?
Look at who conducted the testing, was it independently tested or manufacturers in house testing and look at the test results, what was the BFS, was it in the 30mm range or the 40mm range?

Stab Protection: Does the ballistic armour give stab protection, if so who conducted the testing was it independent testing or manufacturers in house testing and look at the test results?

Options: What comes as standard with the armour and what are extras?


Price?
Break down the cost look at it as personal injury insurance over a 5 year period.
EXAMPLE $850 is the equivalent to $3.43 a week or 51¢ a day, is your safety worth 51¢ a day?
As a security professional purchasing body armour for yourself, it’s a tax right off.

Concealable or External?
a. External gives the potential attacker something to grab a hold of and potentially lose the integrity of the vest and a professional armed attacker something to avoid (Head or Groin shot placement)
b. Concealable gives the potential attacker nothing to grab a hold of and a professional armed attacker will aim for the largest target available Center mass, not seeing body armour not thinking body armour. Old school perception, uncomfortable and hot with today’s current modern material a concealable can be comfortable. Avoid Cotton carriers as they degrade with wear and tear faster than the modern high performance nylons.

Comfort and weight?
a. The thinner and lighter the vest the more expensive it is.
b. A quick rule of thumb body armour weight (Aerial Density) is measured in lbs/Sq Ft the average concealable vest is made of approx 5 Sq/Ft of ballistic material. So when you find the Aerial Density of .80 lbs/Sq Ft multiply by 5 and that will give you the total weight of both the Ballistic panels in lbs, therefore:
Aerial Density.70 = 3.5lbs / Aerial Density.80 = 4lbs / Aerial Density.90 = 4.5lbs

Warranty?
Industry Standard is 5 years for the ballistic panels and 12 to 18 months on the carriers.

Note:
Personally I stay away from laminated armour panels and look for woven, as laminated panels once folded or bent builds a weakness into the laminated panel. I want to be able to fold and roll the ballistic panel into a ball, because when you wear it, it will naturally form to your body (Comfort) unlike a stiff laminated panel.

I liked the part when you say ending the shift with the same amount of holes..excellent..
I know what you mean with the standards etc..

However, many says it will hold all 9mm fullmantle..
And alot of manufactors wasent even aware of the 39B round (copkiller) bullits enormous power in penetrating bodyarmor..

The police officer was shoot with 7 bullets and the vest was meant to take all rounds of that caliber..but they even had a extra plate (trauma plate) and it went right thrue it..

Alot of manufactors has started to sell only NIJ IIIA as minimum just because ti will take all handgun calibers..but even a vest in Class NIJ III must have a extra plates since the 9mm 39B dont stop in the vest without extra plates..

When buying a vest ask if the vest holds the Swedish round 39B..since its a killer bullit!
Just want you guys to be sure youre safe

Look. If you are on a job then ask the following;

Do you need plates?

Plates will offer up to 3 or 4 rounds of 7.62 (AK47) rounds at point blank range...thereafter you will see them fall apart.

A 9mm vest will obvoiusly stop 9mm rounds apart from the Swedish ones you describe. A ceramic set of plates on top of kevlar would stop these rounds you describe.

Best option is an Isreali Kevlar vest (with under underarm and neck protection) donned with a ceramic plate both front and rear. Even better, make sure you are sitting inside a level B6 Landcruiser also. Mind you...doesnt always help.....

Failing all that… Run Away!

Sorry; a closet Monty Python Fan…

Seriously I’d like to know what the muzzle velocity is of this Swedish 39B (bertil) 9 mm round is.

Stay Safe

Roadhog

Muzzle velocity is apparently in the region of regular 9mm. What they swedish engineers did was to make the bullet differently, found the following on another website

During the war in Korea, soldiers started to use so called ”bullet proof” west by introducing different types of lighter materials. This type of west became less heavy than the harnesk type from steel which was used during the Great war. When a bullet strikes a ”bullet proof” west the point of impact is deformed and the penetration ability is reduced.
Swedish ammunition factories constructed a 9 mm bullet which was strong and less likely to deform on impact. The lead core was covered by a jacket of steel, thicker in the front. To reduce friction towards the barrel the steel was covered by a alloy of brass. This cartridge is called m/39B and can be recognized by its red seal for the bullet and primer. This bullet has very good penetration capability. US Army has shown interest in this ammunition and which have been sold to US recently even with an increased load. It has been prohibited in US for civilian use. 9 mm m/39B has been called cops killer by US police because its penetration capacity through a bullet proof west.
