Glock 19 Gen 4 vs. Gen 5: Following the Evolution

The Glock 19, a popular choice among firearm enthusiasts, has undergone significant updates from its Gen 4 to Gen 5 iterations. 

This detailed comparison delves into the key differences, improvements, and performance enhancements between the two generations.

The Glock 19 stands as a hallmark in the world of handguns, known for its reliability, compactness, and versatile design. With the introduction of the Gen 5 variant, Glock enthusiasts found themselves facing an array of changes and improvements. 

This article aims to provide a comprehensive analysis of the Glock 19 Gen 4 and Gen 5, highlighting their respective features and capabilities.

Glock 19 Gen 4: Enhancing Tradition

Design and Ergonomics

The Glock 19 Gen 4 brought notable changes to the Glock 19's design, including an interchangeable backstrap system to cater to various hand sizes. This advancement allowed for a more customized grip, improving comfort and control. Additionally, the dual recoil spring assembly contributed to better recoil management and increased longevity.

Magazine and Ambidextrous Controls

One of the standout features of the Gen 4 was its magazine design. The introduction of a reversible magazine catch accommodated left-handed shooters, enhancing the pistol's accessibility. The Gen 4 magazines were compatible with Gen 3 Glock 19s, providing a degree of versatility if you owned the generation 3 pistol.

Performance and Accuracy

The Gen 4 maintained Glock's reputation for reliability and accuracy. The combination of the dual recoil spring and Glock's Safe Action System delivered consistent performance even under adverse conditions. However, some users noted that the Gen 4's trigger felt slightly different from previous generations.

Glock 19 Gen 5: The Next Level

Marksman Barrel and Improved Trigger

One of the significant upgrades in the Glock 19 Gen 5 was the introduction of the Glock Marksman Barrel (GMB). This enhancement aimed to enhance accuracy by providing better barrel rifling and overall barrel fit. The Gen 5 trigger, with its crisper break and reduced pull weight, further contributed to improved shooting performance.

Ambidextrous Slide Stop and No Finger Grooves

The Gen 5 addressed user feedback by removing the finger grooves present on the Gen 4. This alteration allowed for a more neutral grip that appealed to a broader range of shooters. Additionally, the ambidextrous slide stop catered to both right and left-handed users, promoting ease of use and accessibility.

NDLC Finish and Enhanced Reliability

The Gen 5 featured the nDLC finish on the slide, which provided improved corrosion resistance and durability. This enhancement was particularly valuable for those using their Glock 19 in challenging environments. The redesigned extractor and improved firing pin safety system also contributed to the pistol's reliability.

Improved Magazine Design

The Gen 5 magazines underwent significant changes, with a more durable steel liner and an orange follower for better visual indication of an empty magazine. These alterations enhanced the overall reliability of feeding and cycling, addressing concerns from previous generations.

Glock 19 Gen 4 vs. Gen 5: Making Your Choice

Both the Glock 19 Gen 4 and Gen 5 offer impressive features, but choosing between them depends on individual preferences and requirements.

Factors to Consider

When deciding between the two, consider factors such as ergonomic preferences, shooting style, and the intended use of the pistol. The Gen 4's customizable grip might be advantageous for those who prioritize comfort, while the Gen 5's improved trigger and barrel could attract shooters seeking enhanced accuracy.

Compatibility and Upgrades

The compatibility of Gen 4 magazines with earlier Glock generations could be a crucial point for owners of older Glock models. Conversely, the Gen 5's enhancements in reliability and performance might sway those looking for the latest innovations.


Is the Glock 19 Gen 4 or 5 better?

The Gen 5 boasts enhanced sights and a refined trigger mechanism, in addition to its ambidextrous slide stop, giving it an edge over the Gen 4 in terms of features. Although the variations in dimensions and contours between the Gen 4 and Gen 5 are subtle, they usually result in holsters not being compatible between the two versions.

While both generations are great guns, if you are a left-handed shooter, I would opt for the Gen 5 due to the ambidextrous controls. If you currently own a Gen 4 and are thinking of upgrading to a Gen 5, you have to weigh if that extra money is worth a different trigger system and barrel.

Which generation of Glock is best?

Choosing between the Glock 19 Gen 4 and Gen 5 comes down to personal preference. But the newer Gen 5 has some improvements over the Gen 4 such as the trigger and barrel that can make a good shooter even better. So to answer this question, which generation of Glock is best, we’re going to say the Glock 19 Gen 5.

Will Glock 19 Gen 4 mags fit Gen 5?

The short answer is yes. Glock has not changed the design of their mags since the Gen3 Glock 19, so if you have a stockpile of older magazines, you can rock them in your Glock 19 Gen 5.


In the Glock 19 Gen 4 vs. Gen 5 debate, both generations have their strengths. 

The Gen 4 maintains the Glock tradition while incorporating ergonomic and performance enhancements. 

On the other hand, the Gen 5 represents a leap forward with improved accuracy, durability, and user-focused design elements.

Ultimately, the choice between the two boils down to personal preferences and the intended use of this iconic firearm.
