The Glock pistol has become a ubiquitous firearm, popular with law enforcement, military personnel, and civilians alike. Within the Glock family, there are several generations of pistols, each with its own refinements and improvements. Two of the most commonly discussed generations are the Glock Generation 4 (Gen 4) and Glock Generation 5 (Gen 5). While both are excellent firearms, understanding their differences is crucial for making an informed purchase. This in-depth comparison will delve into the key distinctions between Gen 4 and Gen 5 Glocks.
Key Differences Between Glock Gen 4 and Gen 5
This section highlights the most significant differences between the two generations, allowing for a quick overview. More detailed explanations follow in subsequent sections.
| Feature | Glock Gen 4 | Glock Gen 5 |
|---|---|---|
| Slide: | Rough textured, no front serrations | Smooth, with front serrations |
| Frame: | Dual recoil spring assembly | Single recoil spring assembly |
| Magazine: | Improved magazine with enhanced follower | Improved magazine with enhanced follower, often with different baseplates |
| Trigger: | Improved trigger mechanism | Improved trigger mechanism (further refinements) |
| Front Serrations: | Absent | Present |
| Recoil Spring: | Dual | Single |
| Overall: | More aggressive texture. | Sleeker, refined design. |
Glock Gen 4: A Workhorse Refined
The Glock Gen 4 represented a significant leap forward from previous generations. Glock introduced several features aimed at enhancing both performance and shooter comfort.
Improved Magazine Design
Gen 4 Glocks featured a redesigned magazine with an improved follower. This follower provided smoother and more reliable feeding, reducing the likelihood of malfunctions. This was a significant step up from earlier generations.
Interchangeable Backstraps
Perhaps the most significant change in the Gen 4 was the inclusion of interchangeable backstraps. These backstraps allowed shooters to customize the grip size and feel of the pistol, leading to a more comfortable and secure grip. This customization significantly improved ergonomics for users with different hand sizes. Glocks provided three sizes (small, medium, large).
Dual Recoil Spring Assembly
The Gen 4 utilized a dual recoil spring assembly. While this added a slight complexity in disassembly, many users appreciated the reported increase in longevity. The dual recoil springs offered better recoil control and smoother cycling, potentially resulting in a better shooting experience for some.
Glock Gen 5: Refinement and Modernization
The Glock Gen 5 built upon the successes of the Gen 4, but streamlined the design and incorporated several refinements to further enhance performance and reliability.
Smooth Slide with Front Serrations
The most immediately noticeable change is the smooth slide. Unlike the textured slide of the Gen 4, the Gen 5 sports a smooth, polished surface. However, a welcome addition was the inclusion of front slide serrations. These serrations provide additional gripping points for racking the slide, aiding in one-handed manipulations or under stressful conditions.
Single Recoil Spring Assembly
The Gen 5 simplified the recoil spring system by reverting to a single recoil spring. This simplified field stripping and maintenance, while still maintaining reliable operation. The design also slightly reduced the amount of felt recoil.
Enhanced Trigger Mechanism
The Gen 5 featured an improved trigger mechanism, aiming for an even cleaner, crisper trigger pull. While subtle, this enhancement contributes to improved accuracy and shootability for many users. This refined trigger is often praised for its improvements.
Improved Magazine Release
Although similar to the Gen 4, Gen 5 magazines sometimes have altered baseplates and sometimes incorporate a slightly improved, more reliable magazine release.
Which Generation is Right for You?
Choosing between a Gen 4 and Gen 5 Glock largely depends on individual preferences and priorities. The Gen 4 offers interchangeable backstraps, a potentially longer lasting dual recoil spring system, and a more aggressively textured grip. The Gen 5 offers a smoother, sleeker design, simplified disassembly, front slide serrations, and an often slightly improved trigger.
Gen 4 Pros:
- Interchangeable backstraps for customized grip
- Dual recoil spring system (some users report increased longevity)
- Aggressive texture on the slide for better grip
Gen 4 Cons:
- More complex disassembly due to the dual recoil spring.
- Textured slide is more susceptible to wear.
Gen 5 Pros:
- Sleeker, more modern design
- Front slide serrations
- Simplified disassembly
- Improved trigger
- Smoother slide action
Gen 5 Cons:
- Lack of interchangeable backstraps (although aftermarket options are available).
Ultimately, both the Gen 4 and Gen 5 Glocks are highly reliable and capable firearms. The best choice depends on individual needs and preferences. Handling both models before purchasing is highly recommended to experience the subtle but important differences firsthand.
