For decades the U.S. military has used full metal jacket (FMJ) rounds for their pistols, but are finally switching to jacketed hollowpoints (JHP).
The announcement for the monumental shift was made at the U.S. Army’s Picatinny Arsenal in New Jersey, where military lawyers said the United States never signed the Hague Convention more than a century ago, and therefore are not technically prohibited from using hollowpoint ammunition.
The major push for switching ammo types came out growing concern for innocent bystanders. In the urban combat today’s troops increasingly find themselves in, over-penetration is not an option.
FMJ’s, which largely maintain their shape at the point of impact and excel at energy transfer, can potentially pass through their intended target and strike another, unintended target.
JHP’s, on the other hand, quickly expand at the point of impact, causing a more significant wound channel while decreasing the chance of over-penetration.
The military still plans to use FMJ’s for training purposes, but when it comes to combat, all troops will soon be equipped with JHP’s.
That being said, the caliber of choice has yet to be determined, though many experts believe that based on FBI data, the 9MM is a solid contender.
