What cartridge does the M17 handgun utilize?

The M17 handgun utilizes the 9x19mm Parabellum cartridge, also known as 9mm NATO. This caliber is widely recognized and utilized by military and law enforcement agencies around the world due to its effective range, manageable recoil, and high capacity, making it suitable for a wide variety of shooting scenarios. The M17 was adopted by the U.S. Army as its standard sidearm, replacing the M9, and was designed with modern features that enhance its usability while maintaining compatibility with the existing ammunition supply. The choice to use the 9mm Parabellum aligns with trends in military firearm design that favor lighter, higher-velocity rounds for better performance in dynamic operational environments.
