It is important to note that Level II and III-A all stop the overwhelming majority of pistol projectiles you are ever likely to encounter (plus 12 gauge, OO buckshot), and also to know that NO armor is ever 100% ‘bulletproof’ under ALL conceivable circumstances.
*We do not offer Level II-A as it provides slightly less protection than a Level II without any significant cost savings.
**We do not offer Level III due to the thickness and weight of the ballistic material. The door would end up weighing almost 900 pounds if made to a Level III.
