All Glock Models

Glock pistols are celebrated globally for their durability and dependability, making them a top choice for everything from target practice to personal defense. However, with so many models available, finding the one that fits your needs can feel overwhelming.

A quick glance at the Glock lineup reveals a dizzying array of numbers and codes, each with a specific significance. To clear up the confusion, let’s break down what each model offers and how to interpret those mysterious designations.

Glock Model Numbers and Codes

Every Glock comes with a unique model name or code. The very first Glock, the Glock 17, made its debut in 1982. From that point onward, Glock has maintained a consistent naming convention: each pistol is identified by the brand name followed by a number—and sometimes additional letters, like the Glock 17 Gen 5 MOS.

Here’s what the components of a Glock model name mean:

Model Number: Indicates the specific version of the firearm.
Letter Codes: These signify variations of the base model, often highlighting specific features such as slide dimensions or barrel type.
Generational Markings: Found on Gen 4 and Gen 5 models, these labels point to updates or enhancements introduced with newer versions. Earlier generations lack these distinctions.

Glock Numbers and Variants

So, how do these codes translate to actual features, and what’s the best way to differentiate between models? In this guide, we’ll unpack the details of each Glock model ever produced, from their intended purposes to their standout characteristics, helping you make an informed choice.

Let’s dive in and explore what makes each Glock unique!
