What is 9mm largo?

9mm Largo, also known as 9mm Bergmann-Bayard or 9x23mm, is a pistol cartridge that was developed in the early 20th century for military use. It was originally designed for the Spanish military for use in their pistols, such as the Star Model A and B.

The 9mm Largo cartridge is similar in size to the more common 9mm Parabellum, but it has a longer case length and a higher pressure rating. This allows it to achieve higher velocities and more energy compared to the 9mm Parabellum.

Today, 9mm Largo ammunition can be difficult to find, as it is not as widely used as other popular handgun cartridges. However, it is still used in some firearms and can be found through specialty ammunition manufacturers.

Overall, 9mm Largo is a powerful and effective cartridge that can be used for self-defense or target shooting purposes. It is important for shooters to ensure that their firearms are chambered for this specific cartridge before using it.
