what is less lethal

Less lethal launchers are designed to cause pain, but not to kill or cause serious bodily injury. They fire a blunt force round using gas, compressed air, or gunpowder. Once deployed, the round is designed to deliver kinetic energy to the target area.

The desired effect is one where the suspect either becomes incapacitated or, gives up shortly thereafter because they don’t want to get hit again. Multiple-shot version are favored, as follow-up shots are easier to make.

Munitions deployed from these less lethal weapons may injure a person and have caused deaths both in the US and Internationally.

Muzzle Energy

Using standard paintball guns fired at 300 feet per second, ballistic tests show 32.5 joules (24 Ft-Lbs) of muzzle energy and 1 5/8 inches (42mm) of penetration in FBI Spec ballistic gelatin. Shot from a First Strike FSC pistol, using a Carmatech Engineering Nemesis rifled barrel. 0.686” barrel bore.
