Herrington Arms Glock 19/26 5 Round Magazine Extension Review

Let Me Tell You About the Herrington Arms Glock 19/26 5 Round Magazine Extension

For anyone who carries a Glock 19 or the compact Glock 26, the question of magazine capacity often arises. While standard capacity magazines are usually sufficient, there are those moments when just a few extra rounds can make a significant difference. This is precisely the scenario that led me to seek out a solution, and it’s how I found the Herrington Arms Glock 19/26 5 Round Magazine Extension. After years of relying on stock configurations and various aftermarket options, I was on the lookout for an extension that offered a tangible capacity boost without compromising reliability or introducing new issues. The promise of an additional five rounds, manufactured from durable aluminum with Cerakote finishes, certainly piqued my interest. My initial impression upon unboxing was one of solid craftsmanship; the weight felt substantial yet balanced, and the finish looked precise. I had considered a few other options, mostly polymer-based extensions, but the allure of a metal construction for this particular component swayed me. It was a quiet sense of satisfaction, a feeling that I might have found a reliable upgrade.

Real-World Testing: Putting Herrington Arms Glock 19/26 5 Round Magazine Extension to the Test

First Use Experience

My initial testing grounds for this magazine extension were the familiar confines of my local indoor range. I fitted the extension onto a standard Glock 19 magazine, loaded it with Federal HST 147-grain ammunition, and proceeded with a series of drills. The primary focus was on how the extension integrated with the magazine and the firearm itself during rapid firing sequences and reloads. It was immediately apparent that the fit was snug, with no discernible wobble or looseness that can plague less precise extensions. Reloads felt as natural as with a standard magazine, a testament to its intuitive design.

Throughout multiple range sessions, under varying light conditions and ambient temperatures, the extension performed consistently. I experienced no feeding issues or malfunctions attributed to the extension itself. Its performance in the face of repeated live-fire stress was impressive, maintaining its integrity and function.

Extended Use & Reliability

After several weeks of consistent use, which included not just range days but also carrying my Glock 19 daily, the Herrington Arms Glock 19/26 5 Round Magazine Extension has proven its mettle. It has become a permanent fixture on my primary carry magazine, used for both training and everyday readiness. The durable 7075 Aluminum construction has shown no signs of significant wear, beyond minor cosmetic scuffs that are to be expected from a piece of equipment that is actively used.

In terms of maintenance, it’s as simple as cleaning the magazine itself. The Cerakote finish has held up remarkably well, resisting scratches and abrasions from holster wear and handling. Compared to some polymer extensions I’ve used in the past, which could develop cracks or become loose over time, this aluminum extension feels significantly more robust. It’s a piece of kit that instills confidence through its unwavering reliability.

Breaking Down the Features of Herrington Arms Glock 19/26 5 Round Magazine Extension

Specifications

The Herrington Arms Glock 19/26 5 Round Magazine Extension is precisely machined from 7075 Aluminum, a material renowned for its high strength-to-weight ratio, making it both durable and lightweight. This particular model is designed to increase the capacity of Glock 19 and Glock 26 magazines by 5 rounds, bringing the total capacity to a respectable 19 rounds for a Glock 19 magazine and 11 rounds for a Glock 26 magazine, both chambered in 9mm Luger. The extension comes with a choice of finishes, including FDE, OD Green, or Sniper Grey Cerakote, alongside a standard Black Anodized option, allowing for customization to match your firearm’s configuration.

The choice of 7075 Aluminum is a significant factor in the extension’s performance. This aerospace-grade aluminum offers superior impact resistance and rigidity compared to many polymer alternatives. This means it’s less likely to deform or crack under stress, which is crucial for a component that directly interacts with the magazine’s feeding mechanism and the firearm’s magwell. The +5 Round capacity enhancement is the primary functional benefit, providing more ammunition at the ready without significantly altering the magazine’s overall ergonomics.

Performance & Functionality

The core function of the Herrington Arms Glock 19/26 5 Round Magazine Extension is to reliably add capacity, and it accomplishes this with impressive efficacy. During extensive live-fire exercises, the transition from a standard magazine to one equipped with this extension was seamless. Rounds fed consistently from the fully loaded extension without any hesitation or failure to chamber. This level of reliability is paramount for any firearm accessory, especially one intended for defensive use.

The extension’s design ensures that the added rounds are presented to the firearm’s feed ramp without issue. I experienced zero misfeeds or stoppages that could be attributed to the extension itself. It performed its intended task flawlessly, exceeding my expectations for a simple capacity-enhancing component.

Design & Ergonomics

Herrington Arms has clearly prioritized a high-quality finish and precise machining with this product. The 7075 Aluminum provides a tactile feel that is both solid and premium. The available Cerakote and Anodized finishes are not just for aesthetics; they also offer a degree of corrosion resistance and a non-slip surface.

The extension is designed to integrate smoothly with the Glock magazine’s baseplate, offering a comfortable grip extension that doesn’t feel overly bulky. When seated in the firearm, it presents a cohesive unit without any pronounced edges or awkward contours. It feels like a natural extension of the magazine, rather than an add-on.

Durability & Maintenance

Given its 7075 Aluminum construction and robust finish options like Cerakote, the durability of this extension is expected to be very high. After a considerable amount of real-world use, I’ve observed no structural degradation, such as cracks or deformation. The material resists impacts and scrapes well, and the finish remains largely intact.

Maintenance is straightforward, involving the same cleaning and lubrication routine as the rest of your firearm magazines. The design doesn’t introduce any complex parts or require specialized tools for routine care. Any potential failure points would likely stem from improper installation or extreme abuse, neither of which I have encountered.

Accessories and Customization Options

The primary customization offered with the Herrington Arms Glock 19/26 5 Round Magazine Extension lies in its varied color finishes. Options like FDE, OD Green, and Sniper Grey Cerakote allow users to aesthetically match their firearm or preferred gear setup. The Black Anodized finish provides a classic, understated look.

Notably, this extension does not come with a magazine; it is a separate component designed to be added to an existing compatible magazine. It’s also important to note that it is not recommended for use with Gen 1-3 OEM Glock mags if using a magwell, and it does not fit Magpul GL9 magazines. These exclusions are important considerations for potential buyers.
