Faxon Firearms Modular G19 9mm Combo Mag Extension Review

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

The Faxon Firearms Modular G19 9mm Combo Mag Extension aims to offer Glock 19 owners enhanced magazine capacity with a customizable approach. This particular model focuses on providing flexibility in extending magazine function for a popular handgun platform.

The need arose from a desire to maximize carrying capacity without resorting to proprietary, non-standard magazines. I was looking for a reliable way to add a few extra rounds to my existing Glock 19 magazines, ensuring compatibility and durability.

My initial impression was positive, noting the solid construction and the quality feel of the machined aluminum. The anodized finish felt robust, hinting at good wear resistance. I had considered other brands that offered similar extensions, but Faxon’s reputation for quality firearm components tipped the scales.

The first reaction was one of practicality; this was a functional upgrade designed to solve a specific problem, and it seemed to fit the bill perfectly. This modular extension promised an increased round count, a feature I’ve come to value.

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

First Use Experience

I tested this mag extension primarily at my local indoor range during several extended shooting sessions. The environment was controlled, focusing on how the extension performed under direct firing conditions and repeated magazine changes. I also conducted some dry-fire drills at home to assess the ergonomics and magazine seating.

The extension performed admirably under rapid-fire scenarios and during sustained use. It handled the recoil effectively, with no noticeable negative impact on the firearm’s function. Seating the extended magazine was as straightforward as a standard Glock magazine, offering a familiar feel.

It was intuitive from the start; there was no significant learning curve involved in attaching the extension or using the modified magazine. The assembly process itself was also remarkably simple, requiring minimal tools and effort.

My only minor surprise was the slight increase in overall magazine length, which is expected but worth noting for those concerned with concealment. It fits snugly and securely, without any wobble or looseness.

Extended Use & Reliability

After a month of consistent use, this mag extension has held up exceptionally well. It’s been loaded and unloaded countless times, subjected to the rigors of range days, and has shown no signs of degrading performance. The increased capacity has become a regular feature of my range bag.

Durability appears to be a strong suit. The 6061 T6 aluminum construction and type 2 anodize finish have resisted scuffs and scratches from regular handling and being dropped on the concrete floor during hasty reloads. There’s no discernible reduction in the magazine’s ability to hold rounds securely or feed them reliably.

Maintenance is straightforward, mirroring that of a standard Glock magazine. A quick wipe-down is usually all that’s needed. I haven’t encountered any issues with debris accumulation or feeding malfunctions, which can sometimes plague extensions.

Compared to some budget extensions I’ve used in the past, this Faxon model feels significantly more robust and less prone to developing play over time. It definitely feels like a premium component.

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

Specifications

The Faxon Firearms Modular G19 9mm Combo Mag Extension is crafted from 6061 T6 aluminum and features a durable type 2 anodize finish. This combination ensures both strength and resistance to wear and environmental factors. The modular design allows users to configure it for a +5 round capacity, which is achieved using a specific spring included in the kit.

The aluminum construction provides a lightweight yet sturdy extension that won’t add unnecessary bulk. Its type 2 anodize offers excellent corrosion resistance and a pleasing matte black finish. The inclusion of a +5 compatible spring is crucial for reliable feeding of the additional rounds.

This extension is specifically engineered for the Glock G19 platform and is tested for compatibility with Glock G19 OEM/factory magazines. This is a key specification to ensure proper function. It’s not recommended for aftermarket magazines, which can have slight variations in their dimensions.

The product requires a torque of 12-15 in/lbs for the assembly screws, a critical detail for secure installation. The combo kit implies a configuration for adding a significant number of rounds, enhancing the firearm’s utility.

Performance & Functionality

This magazine extension performs its primary job exceptionally well: reliably increasing the capacity of a Glock 19 magazine. The +5 round extension allows for more follow-up shots, which is invaluable during range sessions or in defensive scenarios. The feeding of these extra rounds has been consistently smooth, without any hangups or failures.

A significant strength is its integration with factory Glock magazines. This ensures that the feeding geometry remains consistent with what the pistol is designed to handle. The extension doesn’t introduce any noticeable wobble or looseness, providing a secure feel.

One potential weakness, though minor, is the slight increase in the magazine’s overall length. This can affect concealment for users who prioritize a very low profile. However, for range use or open-carry scenarios, this is a negligible trade-off for the added capacity.

Overall, it meets and often exceeds expectations for a magazine extension. The performance is on par with higher-end accessories, offering a reliable way to boost magazine capacity.

Design & Ergonomics

The design of the Faxon Firearms Modular G19 9mm Combo Mag Extension is both functional and aesthetically pleasing. Machined from 6061 T6 aluminum with a type 2 anodize finish, it feels robust and well-made in hand. The finish provides a subtle grip, preventing it from feeling overly slick.

Ergonomically, the extension integrates seamlessly with the Glock magazine. There’s no sharp edge or uncomfortable protrusion that interferes with magazine changes or weapon manipulation. It maintains the familiar feel of the factory magazine, just with added length.

Practical design details include the precise machining that ensures a tight fit. The included assembly screws are robust and easy to handle, even with their specified torque requirements. The overall look is understated and professional, complementing the Glock platform well.

Durability & Maintenance

Under normal range use, this mag extension is likely to last for a very long time. The 6061 T6 aluminum and type 2 anodize finish are highly resistant to the stresses of firearm use. I’ve experienced no signs of cracks, significant wear, or performance degradation over the past month.

Maintenance is refreshingly simple. It primarily involves cleaning the magazine itself, as the extension doesn’t create any new crevices for debris to accumulate. Regular inspections for any visible damage are sufficient for ensuring its longevity.

Potential failure points, though unlikely with proper installation, would be related to the screws if not torqued correctly or if subjected to extreme impact. However, the robust design minimizes these concerns significantly.

Accessories and Customization Options

The combo kit for the Faxon Firearms Modular G19 9mm Combo Mag Extension typically includes the extension body, necessary assembly screws, and a +5 compatible spring. This ensures you have everything needed for installation right out of the box. There are no other major accessories typically bundled with this product.

Faxon offers these extensions in various colors, allowing for a degree of aesthetic customization to match your firearm or personal preference. This modularity means you can mix and match parts if you were to acquire multiple extensions.

The primary “customization” is the choice between different capacity configurations, like the +5 provided in this combo. This allows users to tailor their magazine setup precisely to their needs without compromising reliability. The design is focused on adding capacity rather than integrating complex new features.

Pros and Cons of Faxon Firearms Modular G19 9mm Combo Mag Extension

Who Should Buy Faxon Firearms Modular G19 9mm Combo Mag Extension?

This product is ideal for Glock 19 owners who frequently use their firearm at the range and wish to maximize their magazine capacity for extended shooting sessions. It’s perfect for those who value reliability and prefer to stick with factory magazines. Home defense users who want a few extra rounds on hand without investing in entirely new magazine systems will also find this extension very useful.

Those who prioritize extreme deep concealment for their Glock 19 might want to reconsider, as the added length can make pocket or waistband carry more challenging. Users who primarily rely on aftermarket magazines for their Glock 19 should also look elsewhere, as compatibility is key here.

I would recommend having a set of torque wrenches or drivers capable of measuring in-lbs for proper installation. It ensures the extension is securely attached without over-tightening. Additionally, cleaning supplies for your standard Glock magazines will be essential for ongoing maintenance.
