The M17/M18 Military Designation uses which caliber?

• A. 7.62 x 51mm
• B. 5.56 x 45mm
• C. 9 x 19mm
• D. 7.62 x 39mm

Answer: (C)

The M17 and M18 are U.S. military service pistols chambered for 9x19mm Parabellum. This 9mm cartridge is the standard handgun caliber for modern service pistols because it provides a practical balance of recoil, control, magazine capacity, and stopping power, and both the full-size M17 and the compact M18 share this same chambering. The other options are rifle or different pistol calibers not used by these weapons: 7.62x51mm is a rifle round, 5.56x45mm is the standard rifle cartridge for the M16/AR family, and 7.62x39mm is used by older AK-style rifles. So, the correct match is the 9x19mm.
