A Foundation Built on Evolution
To truly understand the current offerings, it’s essential to trace the evolution of the Glock 17. From its initial introduction, the Glock 17 distinguished itself with its polymer frame, pioneering a new standard in handgun construction. This lightweight yet durable material, coupled with a simple yet effective design, quickly gained popularity. Subsequent generations refined this foundation. Gen 2 brought improvements in ergonomics and materials, Gen 3 introduced the accessory rail for mounting lights and lasers, and now, Gen 5 builds upon these advancements to offer enhanced performance and features. The constant evolution of the Glock 17 reflects the company’s commitment to innovation and responding to the needs of its users. It’s this legacy of improvement that leads us to this detailed comparison of the G17 Gen 3 vs. Gen 5.
Examining the Frame and Design
The frame serves as the structural backbone of a handgun, and the differences between the Gen 3 and Gen 5 G17s are noticeable. The Gen 3 frame, while functional, often features a more pronounced finger groove design. Many shooters found the grooves fit their hands perfectly, providing a comfortable and secure grip. However, other users felt the grooves were poorly placed or didn’t align with their finger placement, leading to a less-than-ideal grip. The Gen 5 aims to address this.
The Gen 5 removes the finger grooves, opting for a more streamlined and adaptable grip. The removal of the grooves allows for a wider range of hand sizes to comfortably hold the firearm. It also includes a more textured grip surface. This enhanced texture improves grip, especially in wet or adverse conditions. The Gen 5 also sees the addition of an ambidextrous slide stop lever. This is a significant advantage for left-handed shooters as they can now easily manipulate the slide stop without changing their grip. The frame design refinements are indicative of the ongoing efforts to optimize ergonomics and cater to a broader user base.
The Slide in Focus
The slide is another key component where the generations diverge. Gen 3 slides are finished with Glock’s proprietary Tenifer finish, known for its hardness and resistance to wear and corrosion. The Gen 5 slides benefit from the newer nDLC (Diamond-like Carbon) coating. The nDLC coating offers similar, if not improved, levels of durability and wear resistance. The Gen 5 slide also features a different profile, with smoother edges and beveled features that contribute to a more modern aesthetic.
The slide cutouts also receive attention. While the Gen 3 slides typically featured the standard Glock slide serrations, the Gen 5 slides have more pronounced, angled serrations at both the front and rear. This design change enhances the shooter’s ability to manipulate the slide, particularly when performing press checks or clearing malfunctions. These seemingly small aesthetic and functional refinements contribute to a noticeable difference in the overall handling and feel of the pistols.
Delving into the Barrel
The barrel is arguably the most crucial component for accuracy. The Gen 3 barrels are known for their reliable performance. However, the Gen 5 introduces the Glock Marksman Barrel (GMB). This new barrel design features more aggressive rifling, improving the projectile’s spin and promoting enhanced accuracy. The GMB barrel also includes a different crown, which can further refine shot grouping. The GMB barrel is often credited as a key contributor to the Gen 5’s overall accuracy improvements, making it appealing to shooters prioritizing precision.
The Trigger’s Transformation
The trigger is the interface between the shooter and the gun. The Gen 3 trigger, while functional, often had a relatively longer pull and a less-defined reset. The Gen 5 incorporates refinements to the trigger mechanism, including the Glock Marksman Trigger (GMT). This trigger often boasts a smoother, more consistent pull with a more tactile and positive reset. This change allows for faster follow-up shots and potentially improves the shooter’s control over the firing process. It’s a subtle change, but one that many shooters find significantly impacts the feel and performance of the gun.
Examining Magazine Considerations
Magazine compatibility is an important practical consideration. While the magazines themselves are designed to be reliable, some adjustments must be considered when swapping between generation pistols. The Gen 5’s magazine well has been altered to allow for a slight magazine well flare, making for easier magazine insertion and reloads. While Gen 3 magazines will function in a Gen 5, Gen 5 magazines are not compatible in Gen 3 without a minor modification to the magazine itself. These modifications are usually simple but something to keep in mind when buying or collecting magazines.
Other Notable Design Details
Beyond the main components, other subtle but important design differences exist. The firing pin safety, the slide lock lever, and other internal components have undergone refinements in the Gen 5. The changes often aimed to increase reliability and enhance the overall operational experience. The sum of these seemingly minor adjustments results in a pistol that, while still recognizably a Glock 17, offers a more refined and optimized experience for the shooter.
Evaluating Performance and Practicality
Beyond individual components, the overall performance and practicality of each generation deserve consideration.
Accuracy in the Field
While both generations are known for their inherent accuracy, the Gen 5 often has a slight edge, thanks to the Marksman Barrel. The tighter tolerances and improved rifling can translate into tighter shot groups, especially at longer distances. The difference may be subtle for many shooters, but it can be significant for those who prioritize precision.
Ergonomics and Handling on the Range
The Gen 5’s redesigned grip, absence of finger grooves, and enhanced texture contribute to a more comfortable and secure grip for a wider range of hand sizes. The ambidextrous slide stop is a significant advantage for left-handed shooters. The Gen 3 grip can, however, be a perfect fit for some. The “best” handling pistol often comes down to individual preferences and hand size. It’s best to try each model to determine which fits your hand better.
Reliability and Longevity
Both the G17 Gen 3 and G17 Gen 5 have earned reputations for exceptional reliability. Glock’s engineering is based on simple principles of reliability. It is important to keep the firearms properly maintained. Proper cleaning, lubrication, and inspection will ensure that both guns will function consistently over time. The changes in the Gen 5, while aimed at enhancing performance, have not compromised Glock’s hallmark reliability.
Cleaning and Maintenance Procedures
Both generations share similar cleaning and maintenance procedures. The Glock design makes disassembly and cleaning relatively straightforward. Regular cleaning and lubrication of the internal components, slide, and barrel are essential for maintaining the gun’s reliability and accuracy.
Customization and Aftermarket Support
The aftermarket for Glock handguns is extensive. Both the Gen 3 and Gen 5 have extensive support for different components such as triggers, sights, and more. The Gen 3 is generally more economical in terms of component costs. However, the Gen 5 offers many updated components as well, with new options being released constantly.
