The soldier wants to wound his enemy so that two others are needed to take the casualty from the battlefield. The police officer's only purpose is to stop an aggressor's felonious assault. But others disagree saying the 5.7x28-mm bullet has only half the weight at 1000 fps less velocity than the 5.56x45 mm NATO cartridge used in the M16 rifle. Dr. Martin L. Fackler of the International Wound Ballistics Association says. The FiveseveN bullet doesn't even come close to matching the wounding capacity of a well-designed expanding 9 mm handgun bullet.
Ballistic data provided by the company lists muzzle velocity but makes no mention of muzzle energy.
The Los Angeles bank robbery shoot out showed us the need for an armor-piercing bullet for police. They can be useful when an officer responds to a call and has this equipment in his patrol car. If he suddenly faces such a threat after he's left the car, you can bet this equipment will not be readily available. When you look at the evolution in the ballistics of ammunition designed for police purposes, it is toward bullets that are far easier to stop in body armor than military spire point bullets that conform to the Geneva Convention. The evolution of body armor has gone from ballistic nylon in 1937 to Kevlar 29 in 1973 and Kevlar 129 in 1988.
