A Foundation in Grip and Frame Design
The Gen 4 Grip
The foundation of any handgun is its grip, the primary interface between the shooter and the firearm. Glock, in its Gen 4, introduced significant changes to the grip design. The Gen 4 models are distinguished by a textured grip surface known as “Gen4 RTF” (Rough Texture Finish). This texture provided a more secure hold, especially in wet or adverse conditions, enhancing control during rapid firing. Further enhancing user customization, the Gen 4 introduced interchangeable backstraps. These backstraps, varying in size, allowed shooters to adjust the grip circumference to better fit their hand size and preferences, ultimately improving ergonomics and comfort. The front strap of the Gen 4 featured finger grooves, designed to provide a natural and secure grip. These grooves were intended to aid in consistent hand placement and control.
The Gen 5 Grip
The Gen 5 ushered in a new era for Glock’s grip design, presenting a distinct departure from the Gen 4’s approach. One of the most noticeable changes was the elimination of the finger grooves. Glock made this strategic design decision based on user feedback and a desire for a more universally accommodating grip. Instead, the Gen 5’s frame is textured using a new grip pattern, providing excellent purchase without the potential for the finger grooves to feel uncomfortable or ill-fitting for certain hand sizes. This new texture further contributes to a secure grip, maximizing control during recoil and rapid firing. Adding to the ease of reloading, the Gen 5 incorporated a beveled magazine well. This subtle but significant design change allows for faster and more consistent magazine insertion, crucial during high-stress scenarios or competitive shooting. The Gen 5’s grip design reflects a holistic approach, prioritizing a more neutral and universally comfortable fit for a wider range of hand sizes and shooting styles. The refined grip shape and the elimination of finger grooves allow for a more natural and intuitive grip, promoting better control and accuracy.
Exploring the Slide and Barrel Innovations
Gen 4 Slide and Barrel
The slide, the moving component of a semi-automatic pistol, plays a critical role in cycling ammunition and managing recoil. The Gen 4 slide, while reliable and functional, served as a solid foundation for the Glock platform. The finish on the Gen 4 slides generally offered adequate protection against wear and corrosion.
Gen 5 Slide and Barrel
The Gen 5 saw significant upgrades to the slide, most notably with the introduction of a new finish. The most notable change is the “nDLC” (Diamond-Like Carbon) coating. This coating is incredibly durable, providing superior resistance to wear, scratching, and corrosion. The nDLC coating enhances the slide’s resistance to the rigors of daily use, ensuring a longer lifespan and maintaining a sleek appearance. The barrel, the heart of the firearm, is crucial for accuracy and performance. The Gen 5 barrels introduced a critical advancement: the Glock Marksman Barrel (GMB). The GMB features enhanced rifling designed to improve bullet stabilization and accuracy. This advanced rifling contributes to tighter groupings and increased precision at various distances. The GMB showcases Glock’s dedication to enhancing the performance of its pistols, making the Gen 5 a more accurate platform overall.
A Look at Internal Controls and Mechanisms
Gen 4 Internal Controls
The internal components and controls are integral to the functionality and user experience of any firearm. The Gen 4 featured a tried-and-true recoil spring assembly, which contributed to its overall reliability and consistent performance. The magazine release, a critical control for fast reloads, was positioned for easy access.
Gen 5 Internal Controls
The Gen 5 saw several key modifications to the internal components and controls, notably the introduction of ambidextrous slide stop levers. This addition proved to be a significant advantage, particularly for left-handed shooters, allowing them to operate the slide stop without needing to adjust their grip or switch hands. It also benefits right-handed shooters by enhancing their control and manipulation of the firearm, as they can operate the lever with either hand. In addition to the ambidextrous slide stop levers, the recoil spring assembly in the Gen 5 was redesigned. This revised assembly contributes to improved reliability and recoil management, which further enhanced the shooting experience. The magazine release on the Gen 5 was also revamped. The release was enlarged for easier access and was made reversible, offering greater flexibility for shooters who prefer to customize their setups.
Considering the Magazine Interface
Magazine Compatibility – Gen 4
Magazine compatibility is essential for any firearm. The Gen 4 Glock, as with previous generations, utilized a design that was fully compatible with existing Glock magazines. This compatibility allowed Gen 4 owners to use a variety of magazines, creating flexibility for both new and experienced shooters.
Magazine Compatibility – Gen 5
The Gen 5, while largely compatible with previous generation magazines, does have a few compatibility nuances to consider. While older magazines will function, they may not drop free as smoothly due to the altered magazine well design. This means that when a shooter hits the magazine release button, the magazine may not fall free from the weapon, and may need a slight manual pull to remove the empty magazine. However, Glock magazines from the Gen 5 onwards are fully compatible with the Gen 5.
Analyzing the Trigger Characteristics
Gen 4 Trigger
The trigger, the link between the shooter and the firing process, is of utmost importance for accuracy and control. The Gen 4 maintained the tried and true Glock trigger system, providing a consistent trigger pull and reset.
Gen 5 Trigger
The Gen 5 trigger saw some refinement. Glock worked to enhance the trigger feel. The changes are subtle, but generally, the Gen 5’s trigger is often perceived as having a smoother pull and a more tactile reset, providing the shooter with better feedback and enhancing overall trigger control.
Evaluating Performance in Hand and Handling Dynamics

When considering a firearm, practical performance is important. The Gen 4 Glock offered a well-balanced and controllable shooting experience. The texturing and interchangeable backstraps contributed to solid control during recoil. The ergonomics and design of the Gen 4 made it relatively easy to manage the pistol effectively.
Gen 5 Handling
The Gen 5 delivers improved performance in several aspects. The absence of the finger grooves, combined with the enhanced grip texture, offers a comfortable and secure hold that is more universally compatible. The Glock Marksman Barrel contributes to enhanced accuracy, enabling tighter groupings and extending effective range. The refined trigger and ambidextrous controls further augment the shooting experience, allowing for more precise and efficient handling. The enhanced slide finish and the new spring also contribute to improved reliability. The Gen 5 builds upon the legacy of the Gen 4, adding refinements to make it a superior platform.
