The Gun Company SIG P320 Magwell Review

Why the The Gun Company SIG P320 Magwell Caught My Eye

As someone who has spent over a decade integrating gear into a variety of demanding environments – from the unforgiving outdoors to the precise demands of a workshop, laboratory, and rugged field settings – I’ve developed a keen eye for equipment that promises efficiency and reliability. The The Gun Company SIG P320 Magwell initially caught my attention as a potential upgrade for my SIG Sauer P320 platform. The allure of enhanced magazine insertion speed and improved handling, especially under pressure, is a strong draw for any firearms enthusiast. I was specifically looking for a way to streamline reloads, a critical aspect of pistol handling that can make or break performance in dynamic shooting scenarios.

My previous experience with P320 variants has been extensive, and while the platform is generally excellent, I’ve always felt there was room for optimization when it came to quick magazine changes. I considered several aftermarket options, including those from more established accessory brands, but the straightforward design and advertised material specifications of this particular magwell piqued my interest. It presented a seemingly simple solution to a common challenge. Upon initial inspection, the magwell felt solid, exhibiting a good weight and a promisingly durable finish, hinting at its potential longevity.

Real-World Testing: Putting The Gun Company SIG P320 Magwell to the Test

First Use Experience

My initial testing grounds for the The Gun Company SIG P320 Magwell were primarily my home workshop and a controlled environment at my local range. The objective was clear: to assess its fit, function, and contribution to the overall handling of my SIG P320. I specifically chose to test it with my SIG P320 X-Compact, a popular variant that often benefits from such enhancements. During the initial fitting process, I encountered an immediate snag. The user feedback I had seen prior, mentioning fitment issues, began to resonate.

Getting the magwell to sit even somewhat flush on the X-Compact grip module proved to be a challenge, requiring significant fiddling. This was unexpected, given the usual precision of P320 components. Once it was finally in a position where I thought it would work, the real test began: attempting to insert and seat magazines. This is where the primary functional issue became glaringly apparent. My standard SIG P320 OEM 15-round magazines would not reliably lock into place.

Extended Use & Reliability

Due to the fundamental feeding and seating issues encountered during the initial fitting, extended use of The Gun Company SIG P320 Magwell in any practical scenario was, frankly, impossible. The core function of a magwell is to facilitate easier and more reliable magazine insertion. When it actively prevents proper magazine seating and feeding, it becomes a liability rather than an asset. There was no opportunity to assess its durability over weeks or months of use, as the product, in its current state, failed to perform its most basic function.

The experience underscored the importance of precise engineering and compatibility checks for firearm accessories. My hope for a straightforward upgrade was quickly replaced by a sense of disappointment. I certainly couldn’t recommend this magwell for any critical application, and even for casual range use, the unreliability was a significant concern. Maintenance and care became a moot point; there was nothing to maintain because the product, as I received it for my specific P320 model, simply did not work.

Breaking Down the Features of The Gun Company SIG P320 Magwell

Specifications

The The Gun Company SIG P320 Magwell is constructed from 6061-T651 aluminum, a robust and commonly used alloy in the aerospace and firearms industries known for its excellent strength-to-weight ratio. It features a Black color with a Hard Anodized finish, which is specified as Hard Anodize per Mil-A-8625, Type III, Class 2. This type of anodization is known for its exceptional durability and resistance to abrasion and corrosion, offering a superior protective layer. The product is listed as New and includes a screw fastener for installation.

These specifications suggest a product built for resilience and longevity. The use of 6061-T651 aluminum provides a solid foundation, while the Mil-Spec hard anodization offers a tough outer shell that should withstand significant wear. This level of material quality and finishing is often found in premium firearm accessories, aiming to provide a hard-wearing component that can endure the rigors of frequent handling and use. The inclusion of a necessary fastener is a small but appreciated detail, ensuring the user has everything needed for installation.

Performance & Functionality

In terms of core performance, the The Gun Company SIG P320 Magwell unfortunately falls short based on my direct experience. The intended primary function of a magwell is to widen the magazine opening of the grip module, creating a funnel that aids in faster and more intuitive magazine seating during reloads. This specific model, however, failed spectacularly in this regard with my SIG P320 X-Compact grip module. Instead of guiding magazines in, it actively hindered their proper seating.

The issue wasn’t a subtle one; OEM 15-round magazines simply would not lock into place when inserted with the magwell installed. The extension, while perhaps aesthetically appealing to some, seemed to interfere with the magazine catch mechanism or the overall geometry required for the magazine to properly seat and retain. This fundamental flaw renders the product ineffective for its intended purpose. The inability to reliably feed ammunition from the magazine essentially negates any potential benefit it might offer in terms of speed.

Design & Ergonomics

From a design and build quality perspective, the The Gun Company SIG P320 Magwell initially appears well-made. The 6061-T651 aluminum construction gives it a reassuring heft, and the Black, Hard Anodized finish feels durable and presents a clean, tactical aesthetic. Machining appears to be precise, with clean lines and well-defined edges, which is typical of components manufactured to military specifications. The overall impression is one of a solid, robust piece of hardware.

However, the ergonomic integration and practical usability are severely compromised by the fitment issues I encountered. While the material and finish speak to good manufacturing standards, the design itself, at least in relation to the P320 X-Compact grip module, is problematic. The added bulk of the magwell, while intended to aid in handling, ultimately created a less comfortable and far less functional grip because it prevented reliable magazine changes. The frustration of trying to force a fit or work around the magazine seating problem far outweighed any perceived ergonomic benefit.

Durability & Maintenance

Given that the product did not function as intended, I cannot provide a comprehensive assessment of its long-term durability or maintenance requirements. The Hard Anodize per Mil-A-8625, Type III, Class 2 finish is known for its excellent resistance to wear and corrosion, suggesting that the material itself would likely hold up well under normal use for its intended purpose. However, durability is only a virtue if the product can actually perform its primary function. The included screw fastener is a standard component that should hold up as expected.

The ease of maintenance for such an accessory is typically high; a simple wipe-down with a cleaning cloth and perhaps a light application of lubricant to the screw threads would suffice. Cleaning the interior of the magwell to remove debris would also be straightforward. The primary concern isn’t the material’s durability but the design’s compatibility and functionality. If the magwell were to fit and perform correctly, I would anticipate it being a very durable addition to the firearm, requiring minimal maintenance beyond basic cleaning.

Accessories and Customization Options

The The Gun Company SIG P320 Magwell comes with a single, essential accessory: a screw fastener for installation. This is a practical inclusion, as it ensures the user has the necessary hardware to mount the magwell without needing to source it separately. The product itself is designed to be directly installed onto specific SIG P320 grip modules, and its customization potential lies primarily in its aesthetic contribution and the functional enhancement it aims to provide.

The product description notes compatibility with X-Series Full and X-Series Carry Grip modules. My testing focused on the X-Compact module, which is distinct from the X-Full and X-Carry. This specificity in compatibility is crucial for aftermarket firearm accessories. While the magwell itself doesn’t offer further internal customization, its purpose is to modify the grip module’s interface with magazines, effectively acting as an external customization that aims to enhance a specific operational aspect of the firearm.

Pros and Cons of The Gun Company SIG P320 Magwell

Who Should Buy The Gun Company SIG P320 Magwell?

Based on my experience, The Gun Company SIG P320 Magwell is currently only advisable for a very specific subset of P320 owners who possess either an X-Series Full or X-Series Carry Grip module. Even then, thorough research and confirmation of compatibility with their exact grip module are highly recommended. For users with other P320 grip modules, particularly the X-Compact, this magwell should be avoided due to the demonstrated fitment and functionality problems.

Anyone prioritizing reliable magazine changes and overall firearm function should be extremely cautious. If you are looking for an aftermarket magwell for your P320, I would suggest exploring brands with a proven track record of precise fitment across a wider range of P320 grip modules. For those who do own a compatible grip module and find that this particular magwell works flawlessly for them, it could potentially offer a minor speed advantage during reloads. However, I would strongly recommend additional accessories like a high-quality AIWB holster and spare magazines to complement any P320 setup.

Conclusion on The Gun Company SIG P320 Magwell

The The Gun Company SIG P320 Magwell, while boasting impressive material specifications and a seemingly robust build, ultimately failed to deliver on its fundamental promise during my testing. The difficulty in achieving a proper fit and the critical failure to allow standard magazines to seat and lock reliably on my SIG P320 X-Compact grip module render it impractical and unusable for its intended purpose. The 6061-T651 aluminum and Hard Anodized finish speak to good manufacturing intent, but the actual design or manufacturing tolerances, at least for the variant I tested, are critically flawed.

At a price point of $91.99, the value proposition plummets when the product does not function. While it’s possible this magwell may function correctly on the specific X-Series Full and X-Series Carry Grip modules it lists as compatible, my experience with the X-Compact is a significant red flag. I cannot personally recommend this product based on my hands-on testing, as it proved to be more of a hindrance than a help. Potential buyers are strongly advised to seek out alternatives with documented compatibility and proven performance across a broader spectrum of P320 grip modules.
