Known as the 9mm Luger to Sum, the 9x19mm Perabellum cartridge is the most popular ammunition cartridge for handguns in the world, with more than 60% of the world's law enforcement agencies currently using this cartridge. The 9mm semi-automatic Luger was used as the standard issue handgun during World War II for many national militaries, and the ongoing popularity of this ammo testifies to its capabilities as a pistol cartridge. NATO adopted the 9mm in 1955 as their official sidearm cartridge. And 30 years later, the US military exchanged the vulnerable 45 ACP for the 9mm as their official cartridge. Many people debate this decision still, yet less than 10 years later, shooters were able to find the caliber in most every gun store. George Luger developed the cartridge and began selling it for the DWM Luger semi-automatic pistol in 1902. The cartridge is compact, allowing shooters to carry quite a bit of it without the burden of excessive weight. For this reason, many civilian gun owners and police agencies have moved away from other handguns and now favor 9mm semi-automatic handguns. The ammunition availability has followed this trend, with cartridges more plentiful and easier to find than other calibers. The FBI even switched to it before they started using the more modern 10mm cartridges. While not the most powerful, this ammunition allows for better control and follow-up shots, which helps novice shooters who are unable to effectively deal with larger cartridges. Depending on your level of skill and experience, you may want to speak with a salesperson about the best 9mm cartridge for your needs. Though the cartridge does not have as much stopping power as the 45 ACP, it remains a great choice for many shooters due to being lightweight and compact. Used in conflict resolution around the planet, the 9mm has also been used by hunters. Modern JHP loads serve well in hunting applications and you can usually find them easily.
