Centennial Defense Systems Extended Control Kit for Gen 5 Glock Review

Ready to Know the Truth About the Centennial Defense Systems Extended Control Kit for Gen 5 Glock?

As an equipment specialist with over a decade of putting gear through its paces across diverse environments, I’m always on the lookout for upgrades that enhance functionality without sacrificing reliability. My latest acquisition, the Centennial Defense Systems Extended Control Kit for Gen 5 Glock, arrived with the promise of improved ergonomics and a touch of aesthetic refinement for my Gen 5 Glock pistol. I came to this kit seeking a subtle yet significant improvement to the tactile controls of my daily-carry firearm, particularly the slide release, which has been a minor point of contention with my particular hand size and grip preference. While my initial impressions of the stainless steel pins and slide lock lever were positive, the included slide release presented an immediate question mark, prompting a deeper dive into its performance. I had considered other aftermarket options, but the integrated nature of this kit, combining multiple components from a single manufacturer, appealed to my desire for a cohesive upgrade. My initial reaction was one of cautious optimism, hoping this kit would finally address those small but persistent ergonomic niggles.

Real-World Testing: Putting Centennial Defense Systems Extended Control Kit for Gen 5 Glock to the Test

First Use Experience

My testing primarily occurred on the familiar confines of my home workshop and the controlled environment of my local indoor range. The kit was installed on a Gen 5 Glock 19, and the initial impression was overwhelmingly positive regarding the fit and finish. Installation was straightforward; the stainless steel pins and slide lock lever swapped out with factory parts without any binding or need for force.

The real test began on the range. I performed several drills focusing on slide lock engagement and manual slide release, specifically looking for increased surface area and positive tactile feedback. The improved grip provided by the extended controls was immediately noticeable, requiring less deliberate finger movement.

However, the included Tango Down slide release presented a peculiar performance characteristic. While it offered a larger surface, its engagement felt less positive than expected, leading to a couple of instances where it didn’t quite lock the slide back under rapid fire. This was surprising, as I’ve had positive experiences with other extended slide releases.

Extended Use & Reliability

After several hundred rounds and a few months of daily carry, the Centennial Defense Systems Extended Control Kit for Gen 5 Glock has settled into its role. The stainless steel pins and slide lock lever have proven exceptionally durable, showing no signs of wear or degradation. They continue to function flawlessly, providing a subtle but appreciated improvement in manipulation.

The Tango Down slide release, however, remains a point of discussion. While it hasn’t failed to lock the slide back entirely since those initial range sessions, it does require a more deliberate and precise press to ensure engagement, especially under stress or when wearing gloves. This is a stark contrast to the stock slide release, which, while smaller, offered a more consistent and forgiving engagement.

Maintenance has been minimal. The stainless steel components are easy to clean and resist corrosion. I’ve not needed to apply any specific lubrication beyond standard firearm maintenance, and they’ve held up well to exposure to light moisture from sweat and occasional handling in varied workshop conditions. Compared to some cheaper, plated aftermarket parts I’ve used in the past, the Centennial Defense Systems Extended Control Kit for Gen 5 Glock shows superior long-term finish integrity.

Breaking Down the Features of Centennial Defense Systems Extended Control Kit for Gen 5 Glock

Specifications

The Centennial Defense Systems Extended Control Kit for Gen 5 Glock is a three-piece upgrade package. It includes two stainless steel pins, a stainless steel extended slide lock lever, and a Tango Down slide release. The pins and slide lock lever are machined from high-quality stainless steel, offering superior strength and corrosion resistance compared to factory polymer or softer metal components.

These components are designed as direct replacements for most Gen 5 Glock models, meaning no special fitting or modification is typically required for installation. The stainless steel construction promises enhanced durability and a clean, robust aesthetic. It is crucial to note that this kit will NOT fit G36, G42, G43, G43X, G48 or Gen 1-4 Models, a critical distinction for potential buyers.

The use of stainless steel for the pins and slide lock lever is a significant upgrade from the factory parts, which are often made of polymer or a less robust metal. This material choice directly translates to increased longevity and resistance to wear, especially under repeated manipulation or stress. The extended slide lock lever offers a slightly larger surface area for easier engagement, aiding in slide lockback manipulation.

Performance & Functionality

The primary function of this kit is to improve the ergonomics and durability of key control surfaces on a Gen 5 Glock. The stainless steel pins and slide lock lever excel in this regard. Their fit and finish are excellent, and they perform their intended roles without any discernible change in function from the factory parts they replace, beyond an expected increase in robustness.

The main area where performance is a mixed bag is with the Tango Down slide release. While it provides a significantly larger surface area, making it easier to physically grasp, its mechanical engagement is less positive than the OEM part. This can lead to missed slide lockbacks, particularly during aggressive shooting or when not applying firm pressure.

Design & Ergonomics

From a design perspective, the Centennial Defense Systems Extended Control Kit for Gen 5 Glock offers a subtle yet noticeable aesthetic upgrade. The stainless steel pins and slide lock lever have a clean, brushed finish that complements the polymer frame of the Glock. They feel solid and well-machined, conveying a sense of improved quality.

Ergonomically, the extended slide lock lever is a marginal improvement over the stock part, offering a bit more real estate for your finger. However, the Tango Down slide release, while larger, doesn’t translate to better feel. Its profile and the tactile feedback it provides are less intuitive for rapid manipulation than expected, requiring a more precise application of force.

Durability & Maintenance

The stainless steel components within this kit are undoubtedly its strongest suit regarding durability. I anticipate these parts will outlast the firearm itself under normal use. They are inherently resistant to corrosion and wear from friction.

The Tango Down slide release, being a polymer component, is also reasonably durable. However, its functionality is more about the engagement mechanism than the material itself. Cleaning is straightforward, requiring only standard firearm cleaning procedures.

Accessories and Customization Options

This kit is designed as a self-contained upgrade. The primary “accessory” is the Tango Down slide release itself, which is integrated into the kit’s offering. Centennial Defense Systems has provided a functional, albeit with performance caveats, upgraded component.

There are no additional accessories included with this specific kit. The components are designed to replace specific factory parts, and there is no immediate need for further customization beyond what the kit offers, though users can always opt for other grip panels or aftermarket triggers independently.

Pros and Cons of Centennial Defense Systems Extended Control Kit for Gen 5 Glock

Who Should Buy Centennial Defense Systems Extended Control Kit for Gen 5 Glock?

This kit is best suited for Gen 5 Glock owners who are looking to upgrade the durability and aesthetics of their firearm’s internal control mechanisms. If you value stainless steel construction for its longevity and are comfortable with potentially adapting to a different slide release engagement, this kit offers a solid foundation. It is ideal for those who perform regular maintenance and appreciate quality materials in their firearm.

However, if your primary concern is a foolproof, always-engaging slide release for high-speed operations or competition, you might want to stick with the factory part or explore other dedicated slide release options. Those with the excluded Glock models (G36, G42, G43, G43X, G48) will need to look elsewhere for upgrades. A good quality gun cleaning kit and appropriate tools for disassembly would be recommended for installation.

Conclusion on Centennial Defense Systems Extended Control Kit for Gen 5 Glock

The Centennial Defense Systems Extended Control Kit for Gen 5 Glock presents a compelling value proposition for those seeking to enhance the durability and subtly refine the controls of their Gen 5 Glock. The stainless steel pins and slide lock lever are unequivocally excellent upgrades, offering robust construction and a cleaner aesthetic that’s hard to fault. They perform their duties admirably, providing a tangible increase in perceived quality and longevity.

The inclusion of the Tango Down slide release, while well-intentioned for improved ergonomics, is where this kit becomes a more nuanced recommendation. Its performance, while functional for many, did not meet the consistent, forgiving engagement I’ve come to expect from aftermarket parts, particularly under dynamic conditions. This inconsistency is the primary drawback that tempers an otherwise strong offering.

For a price point of $40.49, you receive three upgraded components, two of which are stellar. If you are primarily interested in the durable stainless steel internal upgrades and are willing to potentially adapt to or even replace the slide release component based on your specific needs, then this kit is certainly worth considering. It offers a good blend of quality materials and improved design for those looking to personalize their Gen 5 Glock without breaking the bank.
