Hey guys! Let's dive into a comparison that's been on many gun enthusiasts' minds: the Glock 19 Gen 5 versus the Glock 19 Gen 4. Both are incredibly popular handguns, but there are some key differences that might sway your decision depending on your needs and preferences. We'll break down the features, performance, and overall value of each to help you make an informed choice. So, let’s get started!

A Detailed Look at the Glock 19 Gen 5

The Glock 19 Gen 5 is the latest iteration in the Glock 19 series, and it comes packed with several upgrades and enhancements over previous generations. When we talk about improvements, we're not just looking at cosmetic changes; there are significant mechanical and ergonomic tweaks that enhance the shooting experience. The Gen 5 aims to deliver improved accuracy, reliability, and overall handling. For many, these upgrades make it a worthwhile successor. The key improvements in the Glock 19 Gen 5 revolve around its barrel, trigger system, and overall durability. These enhancements collectively contribute to a more accurate and user-friendly firearm, which is why many shooters favor this model.

One of the most notable features of the Gen 5 is the Glock Marksman Barrel (GMB). This barrel is designed with enhanced rifling, which improves bullet stabilization and, consequently, accuracy. It's not just a small tweak; many users have reported tighter groupings and better overall precision when shooting the Gen 5. In addition to the barrel, the Gen 5 features a smoother trigger pull compared to the Gen 4. Glock has refined the trigger mechanism to provide a crisper break and a more consistent feel, which is crucial for accurate shooting. The improved trigger reduces the likelihood of pulling shots, allowing for better control and confidence, particularly in high-pressure situations or competitions. Furthermore, the Gen 5 includes Glock's nDLC finish, which provides enhanced protection against corrosion and wear. This durable finish isn’t just about aesthetics; it ensures the pistol can withstand harsh conditions and frequent use without showing significant wear. It adds to the longevity and reliability that Glock is known for, making the Gen 5 a dependable choice for both everyday carry and duty use. The removal of finger grooves on the Gen 5 grip is another significant change, catering to a wider range of hand sizes and preferences. Some shooters found the finger grooves on previous generations uncomfortable or restrictive, so this modification enhances ergonomics. The ambidextrous slide stop lever is a welcome addition for left-handed shooters, making the Gen 5 more versatile and user-friendly. This feature ensures that both right-handed and left-handed individuals can operate the firearm efficiently, which is particularly important in tactical situations. The flared magazine well on the Gen 5 also deserves mention. This design makes magazine changes faster and smoother, which is crucial in high-stress scenarios. A wider opening for the magazine allows for quicker reloads, giving shooters a tactical advantage. All these enhancements in the Gen 5 contribute to a more refined and high-performing pistol.

Delving into the Glock 19 Gen 4

The Glock 19 Gen 4 was a significant step up from its predecessors, bringing several updates to the table that improved its ergonomics and performance. While it might not have all the bells and whistles of the Gen 5, the Gen 4 is still a highly capable and reliable handgun that’s widely used by law enforcement, military personnel, and civilian shooters alike. One of the key features introduced in the Gen 4 was the Modular Back Strap (MBS) system. This allowed shooters to customize the grip size to better fit their hands, enhancing comfort and control. The ability to adjust the grip is a game-changer for many, as it ensures a more secure and ergonomic hold, which translates to better accuracy and recoil management. The Gen 4 also featured a more aggressive grip texture compared to earlier generations. This rougher texture provided a more secure hold, even in wet or slippery conditions. A good grip is essential for maintaining control of the firearm, especially during rapid firing or in stressful situations, making this a practical upgrade.

Another notable enhancement in the Gen 4 was the introduction of a dual recoil spring assembly. This system reduces felt recoil and muzzle flip, making the pistol more comfortable to shoot and improving follow-up shot speed. The dual recoil spring helps to absorb more of the recoil energy, reducing the impact on the shooter's hand and wrist. This feature is particularly beneficial for those who spend a lot of time at the range or use the Glock 19 for competitive shooting. The Gen 4 also includes a larger magazine release, making magazine changes easier and faster. This is a practical improvement that enhances the pistol's usability, especially in tactical situations where quick reloads are critical. A larger magazine release allows for easier manipulation, even with gloves on, ensuring a smooth and efficient reload process. Although the trigger on the Gen 4 is not as refined as the one on the Gen 5, it is still a reliable and functional trigger system. Many shooters find the Gen 4 trigger perfectly adequate for their needs, and it can be further customized with aftermarket parts if desired. While the Gen 5's trigger is smoother out of the box, the Gen 4's trigger is still a solid performer and contributes to the pistol's overall reliability. The Gen 4 maintains Glock's reputation for reliability and durability. It’s a workhorse that can withstand a lot of use and abuse, making it a trusted choice for professionals and recreational shooters alike. Its simple design and robust construction mean it can handle a variety of conditions and maintain its performance, which is a significant factor for those who rely on their firearm for personal defense or duty use.

Key Differences: Gen 5 vs. Gen 4

Now, let's get down to the nitty-gritty and highlight the key differences between the Glock 19 Gen 5 and the Gen 4. Understanding these differences will help you determine which model best suits your shooting style and requirements. We’ll break it down into several key areas, including the barrel, trigger, grip, finish, and other features.

Barrel and Accuracy

As mentioned earlier, the Gen 5 features the Glock Marksman Barrel (GMB), which is designed for enhanced accuracy. The improved rifling in the GMB provides better bullet stabilization, leading to tighter groupings and more consistent shots. In contrast, the Gen 4 uses a standard Glock barrel, which is still accurate but doesn't offer the same level of precision as the GMB. If accuracy is a top priority for you, the Gen 5 has a clear edge. The GMB is a significant upgrade that many shooters appreciate, especially those who compete or require high levels of precision. The difference in accuracy might not be noticeable for casual shooters, but experienced marksmen will likely see the benefit. For competitive shooters, the enhanced accuracy of the Gen 5 can translate to better scores and improved performance.

Trigger Performance

The trigger is another area where the Gen 5 sees a notable improvement. Glock refined the trigger mechanism in the Gen 5 to provide a smoother, crisper break and a more consistent trigger pull. This results in better control and reduced chances of pulling shots. The Gen 4 trigger is functional and reliable, but it doesn't have the same level of refinement as the Gen 5 trigger. Many shooters describe the Gen 5 trigger as being lighter and more predictable, which makes it easier to shoot accurately. The smoother trigger pull in the Gen 5 can lead to better shot placement and improved overall shooting experience. For those who value a high-quality trigger, the Gen 5 is the better choice. While aftermarket triggers can improve the Gen 4, the Gen 5’s stock trigger is often preferred by many right out of the box.

Grip and Ergonomics

The grip is another key area of difference. The Gen 5 eliminates the finger grooves that were present on the Gen 4, which many shooters find more comfortable and adaptable to different hand sizes. The finger grooves on the Gen 4 worked well for some but were uncomfortable or restrictive for others. The Gen 5’s straighter grip profile allows for a more natural and consistent grip for a wider range of shooters. Additionally, the Gen 5 features an ambidextrous slide stop lever, making it easier for left-handed shooters to operate. The Gen 4 does not have this ambidextrous feature. The Modular Back Strap (MBS) system on the Gen 4 allowed for some grip customization, but the Gen 5's finger groove-less design is a more universal solution. The Gen 5 grip texture is also slightly more aggressive than the Gen 4, providing a secure hold without being overly abrasive. Ultimately, the grip preference comes down to personal feel, but the Gen 5’s design caters to a broader range of shooters.

Finish and Durability

The finish on the Gen 5 is Glock’s nDLC finish, which provides superior protection against corrosion and wear compared to the Gen 4's finish. The nDLC finish is incredibly durable and helps the Gen 5 withstand harsh conditions and frequent use without showing significant wear. While the Gen 4's finish is still robust, the nDLC finish on the Gen 5 offers an extra layer of protection. This is especially important for those who carry their firearm daily or use it in demanding environments. The enhanced corrosion resistance of the nDLC finish ensures that the Gen 5 maintains its performance and appearance over time, making it a worthwhile upgrade for many users. Durability is a key factor for any firearm, and the Gen 5’s nDLC finish gives it an edge in this department.

Other Features

Beyond the major differences, there are a few other features that set the Gen 5 apart. The Gen 5 includes a flared magazine well, which makes magazine changes faster and smoother. This is a practical improvement that can be particularly useful in tactical situations. The Gen 4 does not have a flared magazine well. The internal components of the Gen 5 have also been tweaked for improved durability and reliability. Glock has made several small improvements throughout the Gen 5 to enhance its overall performance and longevity. These refinements may not be immediately noticeable, but they contribute to the pistol’s reputation for reliability. The Gen 5 also has an updated trigger spring assembly. While both generations are incredibly reliable, the Gen 5 has some subtle enhancements that contribute to its overall robustness.

Performance and Handling

When it comes to performance and handling, both the Glock 19 Gen 5 and Gen 4 are excellent handguns. However, the Gen 5's upgrades do offer some distinct advantages. The enhanced accuracy of the GMB barrel in the Gen 5 translates to tighter groupings and more consistent shots, which is a significant benefit for both recreational and competitive shooters. The smoother trigger pull in the Gen 5 also contributes to better accuracy, making it easier to control the firearm and place shots precisely. During rapid firing, the Gen 5's improved trigger and barrel can make a noticeable difference in performance.

The Gen 4, with its dual recoil spring assembly, is still a very manageable and comfortable pistol to shoot. The recoil reduction in the Gen 4 makes it easier to control, especially during rapid follow-up shots. Many shooters find the Gen 4 to be a well-balanced and reliable performer, even when compared to newer models. While the Gen 5 might have a slight edge in accuracy, the Gen 4 remains a solid choice for those who prioritize ease of handling and reliability. Both pistols are known for their robust construction and ability to withstand a lot of use and abuse, making them dependable options for various shooting applications. The ergonomic improvements in the Gen 5, such as the removal of finger grooves and the ambidextrous slide stop lever, enhance the overall shooting experience for a broader range of users. These changes make the Gen 5 more versatile and adaptable to different hand sizes and shooting styles. The flared magazine well on the Gen 5 also improves handling by making magazine changes faster and smoother, which is a practical advantage in high-stress situations. Overall, the Gen 5 offers a slightly more refined shooting experience, but the Gen 4 remains a highly capable and reliable handgun that performs well in a variety of scenarios.
