9mm ammunition is a type of ammunition that is most commonly used in handguns. It is also sometimes used in submachine guns and carbines. 9mm ammo is inexpensive and relatively plentiful, making it one of the most popular choices for self-defense and target shooting.
Most 9mm ammunition uses a bullet with a diameter of 9mm, although there are some exceptions. The majority of 9mm bullets have a full metal jacket (FMJ), meaning that the entire bullet is encased in metal. There are also hollow point (HP) and +P (increased pressure) versions available.
The main advantage of 9mm ammo is its versatility. It can be used for self-defense, plinking (shooting for fun), and target shooting. It is also available in a variety of different bullet types, so shooters can find the ammo that is best suited for their needs.
