Understanding Glock’s Heritage: A Quick Overview
Before focusing on the specific difference between Gen 4 and 5 Glock models, it’s helpful to understand the broader Glock lineage. While the core principles of its design have remained constant – a striker-fired system, polymer frame, and safe-action trigger – each generation has introduced improvements and refinements. The initial Glock pistols were groundbreaking in their use of polymer for the frame, which made them lighter and more resistant to corrosion. Generations that followed incorporated features like the addition of finger grooves on the grip, which aimed to improve handling. However, the Gen 4 represented a substantial leap forward. It addressed some of the issues that had been identified with earlier models, setting the stage for the even more refined Gen 5. This article aims to examine how the difference between Gen 4 and 5 Glock translates to real-world performance and user experience.
Examining the Core Changes: Gen 4 and Gen 5 Compared
Let’s delve into the specifics, comparing the two generations across several key areas. This comprehensive look reveals the most important difference between Gen 4 and 5 Glock pistols.
Frame and Grip: Sculpting the Handgun Experience
One of the most readily apparent differences lies in the frame and grip. The Gen 4 Glock pistols, while maintaining the proven polymer frame, introduced several key adjustments. The most notable was the inclusion of interchangeable backstraps. This feature allows the shooter to customize the grip size to better fit their hand. This was a significant step toward enhancing the ergonomics of the pistol. Many Gen 4 models also featured a rough texture frame (RTF) to improve grip, especially in wet conditions.
The Gen 5, however, took a different approach. Glock decided to eliminate the finger grooves found on the Gen 4 and earlier models. This decision was, and continues to be, a point of debate among Glock enthusiasts. Some find the finger grooves to be perfectly suited to their hands, providing a natural and secure grip. Others, however, found that the grooves didn’t align with their hand size, potentially making the pistol feel less secure. Glock’s design team believed that removing the grooves would accommodate a wider range of hand sizes and shooting styles. Gen 5 models also feature a new frame texture that has been described as a smoother texture. The Gen 5 also incorporates a beveled magazine well. This subtle change makes reloads faster, as it guides the magazine more easily into the gun. This is a feature that’s often praised by competitive shooters who prioritize speed. This reveals a substantial difference between Gen 4 and 5 Glock frame and grip design.
The Slide: Aesthetic and Functional Enhancements
The slide of a Glock, the component housing the barrel and action, also exhibits key differences between the two generations. Gen 4 Glocks may feature front slide serrations on some models, which help with manipulating the slide.
The Gen 5, however, takes a more consistent approach. Front slide serrations are now standard on all Gen 5 models. This change provides users with additional purchase points for press checks and slide manipulation, something that’s frequently utilized during reloads and tactical drills. More significantly, Gen 5 slides incorporate a nirtided finish. Nitriding is a surface treatment that enhances the slide’s resistance to wear, corrosion, and abrasion. This results in a more durable and longer-lasting finish. This, once again, highlights another difference between Gen 4 and 5 Glock designs.
Internal Improvements: Refining the Glock Experience
While the exterior changes are readily apparent, the internal modifications between the Gen 4 and Gen 5 models are perhaps even more crucial to understanding their overall performance. Gen 4 models introduced a dual recoil spring assembly. This design helps mitigate felt recoil, making the pistol easier to control during rapid firing sequences. The dual spring system also aids in reliability, increasing the lifespan of this critical component.
The Gen 5, however, takes internal improvements to the next level. The key upgrade is the Marksman Barrel, a Glock-designed barrel that incorporates enhanced rifling. This new rifling improves accuracy potential, making the pistol more capable of tight groupings at longer ranges. In addition, the Gen 5 features ambidextrous slide release levers, allowing both right and left-handed shooters to easily manipulate the slide. This design element caters to a broader range of users. Finally, the Gen 5 incorporates an updated trigger mechanism. While Glock’s safe-action trigger system remains, the Gen 5 trigger is often described as having a smoother pull and a crisper break. This can improve the overall shooting experience, making it easier to achieve accurate shot placement. The Gen 5’s refined internals clearly define a significant difference between Gen 4 and 5 Glock performance.
Magazine and Accessory Considerations
The magazines used by the Glock platform also have a notable difference between Gen 4 and 5 Glock design, and the accessories and parts involved. Gen 4 models use the same magazine pattern as the earlier generations.
The Gen 5 saw the introduction of a new magazine design. The new Gen 5 magazines are easily identifiable by their orange follower. This is primarily to identify them for ease of use. While Gen 5 pistols are fully compatible with earlier generation magazines, the orange follower is a visual cue for the latest evolution of the magazine design. Additionally, the base plate on the Gen 5 magazines have seen a minor revision.
Trigger Differences: A Subjective Evolution
The trigger experience is another area where we see a key difference between Gen 4 and 5 Glock iterations. The Gen 4 trigger pull is fundamentally similar to that of the Gen 3 and earlier generations, but the addition of different internal components gives it a slightly modified feel.
The Gen 5 models, on the other hand, boast a significantly improved trigger mechanism. This trigger often exhibits a lighter, smoother pull with a more defined and crisp break. This change can allow for more precise shooting and better target acquisition, giving the shooter more control and a better feel overall.
Performance in Action: How Does It Feel?
Beyond the specifications, the real test of any firearm is its performance on the range. The changes between the Gen 4 and Gen 5 translate into distinct experiences for the shooter. The dual recoil spring assembly in the Gen 4 helps mitigate felt recoil, contributing to a more controlled shooting experience, especially during rapid fire. Its ergonomics and proven reliability are also key assets.
The Gen 5, however, often presents a refined experience. The Marksman Barrel contributes to improved accuracy, allowing shooters to achieve tighter groupings. The enhanced ergonomics, particularly the absence of finger grooves, may result in a more comfortable grip for many shooters. The improved trigger also enhances the overall shooting experience, making it easier to maintain a consistent and accurate shooting style. Each of these factors are key differences between Gen 4 and 5 Glock and should be carefully considered when deciding which platform is best.
Pros and Cons: Weighing the Choices
Before making a decision, it’s crucial to consider the advantages and disadvantages of each generation.
The Gen 4, as a time-tested design, presents several compelling benefits. Its price point is often lower than the Gen 5, making it more accessible to a wider range of buyers. The interchangeable backstraps provide customization for grip size, and it boasts the legendary Glock reliability. However, the finger grooves can be a point of contention for some, and the trigger, while functional, may not be as refined as the Gen 5’s.
The Gen 5 offers advantages that are hard to ignore. The improved trigger, the ambidextrous slide release, and the enhanced Marksman Barrel all contribute to a superior shooting experience. The smoother frame texture, the absence of finger grooves, and the beveled magazine well also add to its overall appeal. However, the Gen 5 typically comes with a higher price tag, and some shooters may find the grip less comfortable compared to a Gen 4 with backstraps installed. The differences in feel and features define the difference between Gen 4 and 5 Glock overall appeal and usage.
