What Does Level 3a Body Armour Stop?
NIJ Level 3a (IIIA) body armour is manufactured to defend the wearer against types of handgun ammunition. This type of armour will also offer protection against blunt force, and reduces the risk of injury from falls and other blows to the torso.
In this guide from the team at Sarkar Tactical, we will focus specifically on NIJ level 3a body armour – what exactly it protects against, its capabilities in the field, and how it compares to armour with different NIJ levels of protection.

What Calibre Rounds Can Level 3a Body Armour Stop?
Level 3a body armour is designed to stop and protect against damage from handgun calibre bullets, such as high-velocity 9mm and .44 magnum ammunition.
Typically made from flexible materials like Kevlar, Spectra, or Dyneema, level 3a body armour is made to provide higher levels of protection than level 2a armour. Level 3a armour plates stop everything level 2a plates protect against, in addition to more powerful pistol rounds with increased penetration.
When is Level 3a Body Armour Typically Worn?
Level 3a body armour is primarily worn by law enforcement officers and security personnel because of how effectively it stops lower calibre ammunition from handguns. Depending on where they operate and their specific roles, these are the types of firearms they are more likely to face on the streets. Level 3a body armour is also suitable for concealment, ideal for plain clothes or undercover forces.
How does the NIJ Rate Body Armour?
The National Institute of Justice (NIJ) tests body armour vests that claim to be “bulletproof” rigorously to determine how resistant they are to different ammunition types and calibres. These tests determine if a wearer would still be ‘alive’ after impact by judging the depth of bullet impact, the degree of deformation, and whether significant injury would be sustained – just stopping a bullet doesn’t ensure that the life is saved.
What Can’t Level 3a Body Armour Stop?
Whilst Level 3a body armour is a useful and effective defence against a wide variety of ballistic threats, it is important to recognise its limitations and where you might need to consider a higher rated option.
Level 3a body armour will not offer suitable protection against rifle rounds or any type of armour piercing ammunition. To defend against these types of threats, you will need body armour rated at NIJ level 3 or above. These are typically encountered in war zones or areas of conflict.
There is a common misconception surrounding NIJ Level 3a vs Level 3 rated body armour, with some people thinking that level 3a armour is stronger because of the nomenclature. In actuality, level 3a body armour can be considered as ‘level 2.5’, providing an upgrade on level 2 rated plates.
All Body Armour Levels
Body armour is categorised into levels determined by its effectiveness in shielding against different ballistic dangers. The NIJ establishes the standards for these armour levels.

Level 3a Body Armour FAQs
Will level 3a armour stop a knife?
Depending on the specific fabric and materials making up the composition of level 3a armour, these plates can provide effective protection against knives and spike injuries, reducing the risk of injury. For the most accurate information, it is recommended to consult the manufacturer.
Will level 3a armour stop shotgun rounds?
Level 3a armour can stop many shotgun rounds, including buckshot and birdshot. However, it might struggle to stop a slug. If an individual wearing Level 3a body armour is hit by a shotgun round, they will likely survive but may be incapacitated due to the significant force of the impact.
Does level 3a armour expire?
Like other types of armour, level 3a armour does have an expiration date that should be included within the manufacturers documentation. Factors like environmental exposure, wear and tear, and ageing can weaken materials and reduce effectiveness overtime.
Conclusion: What Does Level 3a Body Armour Stop?
NIJ Level 3a (IIIA) body armour is designed to protect against all high-powered pistol ammunition, including high-velocity 9mm and .44 magnum rounds, excluding armour-piercing rounds. This type of body armour is suitable for law enforcement and security personnel due to its effectiveness against threats from handguns. These plates are not suitable for protection against rifles and other higher calibre ammunition types – Level 3 + rated armour should be worn in scenarios where these threats are anticipated.
