Common questions

What ammunition does LEOPA regulate?+

It targets handgun ammunition whose projectile is constructed entirely of, or coated with, specified hard metals capable of penetrating soft body armour, reflecting its origin as a response to officer-safety concerns over armour-piercing pistol rounds.

Does LEOPA cover rifle ammunition?+

No, the statute's armour-piercing definition is scoped to handgun projectiles; rifle ammunition with similar penetrating cores is addressed separately or not at all under this law, which is why forensic firearms examiners must confirm caliber and intended use before applying the definition.
