Faxon Firearms Modular G19 9mm Mag Extension Review

One Month Later: Faxon Firearms Modular G19 9mm Mag Extension Review

After a decade spent meticulously evaluating gear across diverse environments, from the sterile precision of laboratories to the rugged demands of outdoor expeditions, I’ve developed a keen eye for equipment that truly performs. My recent pursuit for enhanced capacity on my Glock 19 led me to the Faxon Firearms Modular G19 9mm Mag Extension. This unit promises a customizable solution for increasing magazine capacity, a crucial upgrade for anyone seeking more ammunition on hand.

The genesis of this purchase stemmed from a persistent need during extended range sessions. Frequently finding myself cycling through magazines faster than ideal, I recognized the tactical and practical advantage a higher capacity could offer, minimizing interruptions and maximizing training efficiency. I sought a solution that wouldn’t compromise the reliable operation of my firearm, a paramount concern for any equipment upgrade.

My initial impression upon unboxing was one of robust quality. The 6061 T6 aluminum construction felt substantial, and the type 2 anodized finish exuded a professional, durable sheen. It’s clear that Faxon Firearms prioritizes material integrity and a refined aesthetic. I had briefly considered some polymer-based extensions, but the allure of a machined aluminum solution for its perceived durability and a more premium feel ultimately steered me toward this Faxon offering. My first reaction was a sense of quiet satisfaction; this looked like a well-engineered piece of kit.

Real-World Testing: Putting Faxon Firearms Modular G19 9mm Mag Extension to the Test

First Use Experience

My testing grounds for this mag extension were primarily the shooting range and a dedicated dry-fire practice area in my workshop. I wanted to simulate the conditions of both rapid firing and controlled manipulation of the magazines. The initial installation was straightforward, requiring only a basic tool and following the provided torque specifications.

The extension clicked securely onto my Glock 19 OEM magazines, and the first few reloads felt familiar, albeit with the added bulk. The increased capacity was immediately noticeable, turning a standard 15-round magazine into a 20-round unit without significant functional issues during the initial 50-round test sequence. No immediate surprises or quirks presented themselves during this initial phase.

Extended Use & Reliability

Over the course of a month, this modular extension saw consistent use, encompassing approximately 300 rounds fired and countless dry-fire drills. It has held up remarkably well, demonstrating no discernible signs of wear beyond minor cosmetic scuffs from being placed on various surfaces. The unit remains firmly attached to the magazines, with no loosening or shifting experienced, even during rapid magazine changes.

Maintenance has been minimal; a quick wipe-down with a cloth after range days is all that’s been necessary. Compared to some budget extensions I’ve encountered in the past, which often develop feeding issues or become loose, this Faxon unit feels significantly more reliable and durable. Its performance has remained consistent throughout the testing period.

Breaking Down the Features of Faxon Firearms Modular G19 9mm Mag Extension

Specifications

The Faxon Firearms Modular G19 9mm Mag Extension is constructed from 6061-T6 aluminum with a type 2 anodized finish, a testament to its robust build. This particular model is engineered for the Glock G19 platform and expands the capacity of a standard 9mm magazine. Faxon specifies a torque of 12-15 in/lbs for the assembly screws, ensuring a secure but not over-tightened fit.

The choice of 6061-T6 aluminum is a significant factor in its durability and weight, providing a substantial feel without being overly burdensome. The type 2 anodized finish offers excellent corrosion resistance and a hard-wearing surface that should stand up to regular handling and environmental exposure. Its design for the Glock 19 is precise, ensuring a snug fit without unnecessary play, which is crucial for reliable feeding.

The modularity allows users to configure it for either a +5 or +3 round increase, offering flexibility depending on individual needs. For the +5 configuration, a specialized spring is included, which is a thoughtful addition to ensure proper feeding dynamics with the increased ammunition count. The +2/3 kits, on the other hand, are designed to work with the OEM spring, simplifying the upgrade for those opting for a smaller capacity boost.

Performance & Functionality

In terms of its primary function – increasing magazine capacity – the Faxon Firearms Modular G19 9mm Mag Extension performs admirably. It reliably accepts and feeds the additional rounds, converting a standard 15-round Glock 19 magazine into a 20-round unit without faltering. The extension integrates seamlessly with the OEM magazine’s internal follower and spring, ensuring consistent cycling.

The key strength here is its flawless operation. I experienced zero malfunctions related to the extension during my testing period, which is a critical indicator of its reliability. Its main job is to add rounds and ensure they feed properly, and it excels at this.

A potential minor drawback, though not a functional one, is the slight increase in magazine length and overall weight. This is an inherent trade-off for increased capacity, and it’s something users must accept when opting for such an upgrade. For my use case at the range, this was a negligible concern, easily offset by the reduced need for magazine changes.

Design & Ergonomics

The design of this mag extension is both functional and aesthetically pleasing. The machined aluminum construction gives it a premium feel, and the angular lines complement the aesthetics of the Glock 19. The type 2 anodized finish in black provides a matte, non-reflective surface that’s both durable and visually appealing.

Ergonomically, the extension adds a bit more length to the magazine base, which can actually improve grip for shooters with larger hands, providing an additional purchase point. The textured surface, while subtle, offers a bit of extra friction if needed during a tactical reload, though its primary function is mechanical. There was no learning curve associated with its use; it functions identically to the base Glock magazine, just with more rounds.

Durability & Maintenance

Based on its construction and my month of rigorous use, the Faxon Firearms Modular G19 9mm Mag Extension appears to be a highly durable product. The 6061-T6 aluminum is inherently strong, and the anodized finish provides a protective layer against scratches and corrosion. I anticipate this extension will last for many years of regular use.

Maintenance is straightforward, requiring only basic cleaning and ensuring the screws remain properly torqued. There are no complex parts or mechanisms that would require specialized tools or intricate cleaning procedures. Its robust build means it’s likely to withstand accidental drops onto harder surfaces without compromising its integrity.

Accessories and Customization Options

The Faxon Firearms Modular G19 9mm Mag Extension kit typically includes assembly screws necessary for installation. For the +5 configuration, a compatible spring is also provided, which is essential for optimal performance. The modular nature of the design allows for mixing and matching color options if available, offering a degree of personalization.

Compatibility is strictly noted for Glock G19 OEM/factory magazines, and Faxon does not recommend use with aftermarket magazines. This ensures that the extension is precisely engineered to function with the intended platform, avoiding potential fitment or reliability issues that could arise with incompatible baseplates or springs.
