How To Tell What Gen Glock You Have

How to Tell What Gen Glock You Have

Knowing your Glock generation can be important for various reasons, from finding the right parts to understanding its features. While Glock doesn't explicitly label the generation on the firearm itself, several key identifiers can help you determine precisely which generation you own. This guide will walk you through the process, covering the distinct characteristics of each generation.

Identifying Your Glock Generation: A Visual Guide

Glock pistols have undergone several significant design changes throughout their history, leading to distinct generations. These changes are often subtle but crucial in pinpointing your Glock's generation. Here's a breakdown focusing on the most prominent differences:

Generation 1 (Gen 1)

• Key Features: Simplest design, no finger grooves on the grip, square trigger guard, no rail for accessories, and a simpler slide finish.
• Identifying Marks: Look closely at the grip. The lack of finger grooves is the most noticeable characteristic of a Gen 1 Glock.

Generation 2 (Gen 2)

• Key Features: Introduced finger grooves on the grip for enhanced ergonomics. Still retains the square trigger guard and lack of accessory rail.
• Identifying Marks: The addition of finger grooves is the main differentiator. Compare your Glock's grip to the Gen 1; the grooves are immediately apparent.

Generation 3 (Gen 3)

• Key Features: This generation added an accessory rail under the barrel, allowing for lights, lasers, and other tactical accessories. The trigger pin is also changed, making disassembly slightly different than the previous generations. The improved finger grooves and a slightly different backstrap design are also worth noting.
• Identifying Marks: The presence of the accessory rail is the most prominent feature. Also, observe the trigger pin; Gen 3 Glocks have a different design.

Generation 4 (Gen 4)

• Key Features: Glocks of this generation feature interchangeable backstraps for customized grip size, dual recoil springs for smoother operation, and improved trigger design. The magazine release is also larger and more easily accessible.
• Identifying Marks: The interchangeable backstraps are a key identifier. The larger magazine release is another significant change. Look for these features.

Generation 5 (Gen 5)

• Key Features: The Gen 5 Glocks feature a new Marksman barrel, an improved trigger (without a trigger safety), and a smoother slide finish. They also removed the finger grooves, returning to a more minimalist grip similar to the Gen 1, but with modern improvements.
• Identifying Marks: The absence of finger grooves and the different slide finish are the most noticeable aspects. Also, the trigger should feel different compared to earlier generations.

Beyond Visual Inspection: Serial Number Clues

While visual inspection is the primary method, some Glock owners find clues within the serial number itself. However, this is not a reliable method as the relation between the serial number and the generation is not universally consistent and can vary across different models and manufacturing periods. Therefore, use this as a secondary method to confirm your findings.

Consult a Glock Expert if Unsure

If after careful examination you are still unsure, consider seeking assistance from a firearms expert or a reputable gun shop. They can provide a definitive answer and help you understand your Glock better.
