Level 3A will stop up to 44 magnum 100% made in the USA
Heracles Research body armor has been tested and rated to protect the wearer against threats within the specified NIJ rating level of your vest; no armor is 100% bulletproof. Specialized armor piercing bullets and ultra high velocity rounds may not be stopped by armor. No soft body armor will completely protect against rifle or long gun ammunition. For protection against rifle threats, Heracles Research offers NIJ Level IV hard armor to be used in conjunction with your soft body armor. Always refer to your ballistic panel inserts to determine the level of your armor.
“It is absolutely essential that those who select body armor and each officer who wears it realize that there is no such thing as a bulletproof vest. The routine use of appropriate soft body armor significantly reduces the likelihood of fatal injury, but 100% protection in all circumstances is impossible. Body armor selection is to some extent a trade-off between ballistic protection and wear ability. The weight and comfort of soft body armor is inversely proportional to the level of ballistic protection that it provides.” — National Institute of Justice
