The marking "9x19" on your Glock 17 indicates the caliber of ammunition it's designed to fire. Understanding this marking is crucial for safe and responsible firearm ownership. This post will delve into the meaning of "9x19," its significance for Glock 17 owners, and why this specific designation is used.
Deciphering the 9x19 Caliber
The "9x19" marking is a concise way of describing the cartridge's dimensions. Let's break it down:
- 9: This refers to the approximate diameter of the bullet, measured in millimeters. It's roughly 9mm.
- 19: This indicates the length of the cartridge case, also measured in millimeters.
Therefore, 9x19 signifies a 9mm bullet within a 19mm long cartridge case. This specific cartridge is also commonly known as the 9mm Parabellum, 9mm Luger, or simply 9mm.
Why is 9x19 the Standard for the Glock 17?
The Glock 17, a highly popular and widely used handgun, is chambered in 9x19 because this caliber offers a compelling balance of factors:
- Stopping Power: 9x19 offers sufficient stopping power for self-defense and law enforcement applications. While not the most powerful handgun round, it provides a good balance between stopping power and manageable recoil.
- Accuracy: The 9x19 cartridge is known for its relatively high accuracy, especially when fired from a well-maintained handgun like the Glock 17.
- Capacity: The Glock 17's magazine capacity is often cited as one of its advantages. The 9x19 cartridge allows for high-capacity magazines without making the firearm overly bulky or difficult to handle.

- Cost-Effectiveness: 9x19 ammunition generally tends to be more affordable than some other handgun calibers, making it a cost-effective option for practice and self-defense.
Other Caliber Markings You Might See
While the Glock 17 primarily uses 9x19, it's worth noting that Glock also produces variants chambered in other calibers. You might see other markings like:
- .40 S&W: A larger caliber offering more stopping power but with increased recoil.
- .45 ACP: An even larger caliber with significant stopping power but noticeable recoil.
