How to Tell What Generation a Glock is

Glocks are incredibly popular handguns, known for their reliability and straightforward design. However, the Glock pistol has gone through several generations of improvements and modifications. Knowing the generation of your Glock can be important for understanding its features, potential issues, and even its value. This guide will walk you through how to easily identify your Glock's generation.

Key Differences Between Glock Generations

Before diving into identification methods, let's briefly discuss some key differences between the generations. These variations are crucial for accurate identification:

• Generation 1 (Gen 1): Known for their lack of finger grooves, smooth trigger, and a simpler design. These are the earliest models and generally lack some of the safety features found in later generations.

• Generation 2 (Gen 2): Introduced finger grooves on the grip for improved ergonomics. They retained the smooth trigger from Gen 1.

• Generation 3 (Gen 3): This generation brought about several significant improvements including an accessory rail for mounting lights and lasers, improved ergonomics, and a slightly modified trigger.

• Generation 4 (Gen 4): Featured interchangeable backstraps for a more customizable grip, a modified trigger, and a dual recoil spring assembly for reduced recoil and improved reliability.

• Generation 5 (Gen 5): Removed the finger grooves, incorporated an improved trigger with a smoother pull, and featured an ambidextrous slide stop lever. They also often utilize a Marksman barrel.

How to Identify Your Glock's Generation

There are several ways to definitively determine your Glock's generation:

1. Check the Serial Number

The serial number often provides a clue, though it's not foolproof. The prefix of the serial number sometimes indicates the generation. For example, certain prefixes have historically correlated with specific generations, but this is not a consistent method across all models and can vary slightly due to manufacturing changes. Refer to online resources or Glock forums for more detailed serial number decoding assistance. This method should be used in conjunction with the other methods mentioned below.

2. Examine the Physical Features

This is the most reliable method. Closely inspect your Glock for the following features:

• Finger Grooves: Gen 1 lacks finger grooves, Gen 2 has them, Gen 3 has them, Gen 4 has them but also offers interchangeable backstraps, and Gen 5 removes the finger grooves.

• Accessory Rail: Gen 3 and later generations have an accessory rail under the barrel for attaching tactical accessories.

• Interchangeable Backstraps: Only Gen 4 and later include this feature.

• Trigger: The trigger shape and feel have slightly evolved over the generations. While not definitive on its own, a smoother trigger is generally indicative of a later generation.

• Slide Stop Lever: Gen 5 Glocks have an ambidextrous slide stop lever.

3. Consult Glock Resources

You can search online for images and detailed specifications of each Glock generation. Compare the features of your Glock to the images and descriptions to confirm its generation.

Beyond the Generation: Model Variations

It's crucial to remember that Glock produces various models within each generation (e.g., Glock 17, Glock 19, Glock 21). While the generation determines the overall features and design, the model number specifies size and caliber.

By combining these methods, you can accurately determine the generation of your Glock. This information is valuable for maintenance, upgrades, and understanding the unique features of your firearm. Remember to always handle firearms safely and responsibly.
