9X19
Otherwise known as 9mm, 9mm NATO, Parabellum, 9mm Luger and 9Mil. This is the absolute most popular self-defense cartridge throughout the world. The US military trusts it, the FBI is switching back to it (or already has), and this is what my own EDC gun is chambered in—and what I tell people to get whenever I talk to someone new to concealed carry.Projectile technology has come a very long way for the 9mm round. So much so, in fact, that it has very similar ballistics to the bigger rounds, but doesn't come with the steeper price tag. Neither do they produce the same amount of felt recoil. Overall, this is one of the top self-defense cartridges you can buy.
