What Makes Agency Arms Sig Sauer P320 9mm +5 Pistol Magazine Extension Stand Out?
The Agency Arms Sig Sauer P320 9mm +5 Pistol Magazine Extension is a product that promises to enhance the capacity and handling of your Sig Sauer P320 9mm pistol. Marketed by Agency Arms, a company known for its high-end firearm modifications, this extension aims to provide not just additional rounds, but also improved ergonomics and a tactical edge. It’s a product that immediately caught my eye, given my appreciation for well-designed and functional firearm accessories.
I was looking for a reliable and aesthetically pleasing magazine extension to increase the capacity of my P320 for competition use and, frankly, to reduce the number of magazine changes at the range. I wanted something that felt solid, looked good, and didn’t compromise the reliability of my pistol.
Upon unboxing, the anodized aluminum construction immediately stood out, conveying a sense of quality and durability. The weight felt substantial, and the dot matrix panel offered a nice touch for personalization. My initial impression was a mix of excitement and slight apprehension, wondering if the installation process would live up to the initial user reviews I had glanced over.
While there are other magazine extensions available for the P320, such as those from Magpul and Taran Tactical Innovations, I chose the Agency Arms version primarily for its aesthetics and reputation for quality. The Agency Arms extension seemed to offer a more refined design and a promise of enhanced ergonomics that the others didn’t quite match. My primary focus when selecting this product was reliability and the improved grip ergonomics over sheer capacity, which some of the other extensions promised.
My first impression was cautiously optimistic. The visual appeal and feel of the extension were excellent, but I was slightly concerned about the installation difficulties mentioned by some users.
Real-World Testing: Putting Agency Arms Sig Sauer P320 9mm +5 Pistol Magazine Extension to the Test
First Use Experience
My initial testing took place at an outdoor shooting range during a relatively dry and cool day. I ran several magazines through my P320, focusing on drills that involved rapid magazine changes and one-handed manipulations. I wanted to assess the impact of the extension on both reloading speed and overall handling.
The Agency Arms Sig Sauer P320 9mm +5 Pistol Magazine Extension performed adequately in the initial dry conditions. However, the added length did require a slight adjustment in my grip during reloads. There were no immediate malfunctions, but I did notice that the extended ledge, while intended for one-handed manipulations, felt a bit sharp against my hand.
After the first use, the installation proved to be a chore and a sticking point. The user feedback I read about filing down tabs on the magazine to get it to slide on and then pressing in the center so the locking set screw could even go in came to fruition. This initial experience was frustrating and time-consuming.
Extended Use & Reliability
After several weeks and hundreds of rounds fired, the Agency Arms Sig Sauer P320 9mm +5 Pistol Magazine Extension has held up reasonably well. The anodized finish has proven to be quite durable, showing only minor signs of wear around the edges. This is after repeated drills and practice at the range.
However, there has been a single incident of a failure to feed when the magazine was fully loaded with the +5 extension. I do not know if this was from the magazines I was using or the extension itself. Maintenance involves simply wiping down the extension after each range session and occasionally lubricating the magazine spring. Cleaning has been a straightforward process.
Compared to using the standard capacity magazines, the Agency Arms Sig Sauer P320 9mm +5 Pistol Magazine Extension offers a definite advantage in terms of round count, but at the expense of added weight and slightly compromised reliability. The added weight is noticeable and may be a concern for some users.
Breaking Down the Features of Agency Arms Sig Sauer P320 9mm +5 Pistol Magazine Extension
Specifications
The Agency Arms Sig Sauer P320 9mm +5 Pistol Magazine Extension is specifically designed for 17-round 9mm Sig Sauer P320 magazines. It is not compatible with the AXG magwell, but is compatible with the Agency Arms X-Series Magwell and the factory Sig Sauer magwell. The extension increases the magazine capacity by 5 rounds in 9mm, or 4 rounds in .40 S&W and .357 SIG.

These specifications are significant because they dictate the compatibility and performance of the extension. The material and design directly influence the durability, weight, and overall handling of the pistol.
Performance & Functionality
The primary function of the Agency Arms Sig Sauer P320 9mm +5 Pistol Magazine Extension is to increase magazine capacity, which it does effectively. The added rounds are a significant advantage in competition or tactical scenarios. However, the potential for reduced reliability with a fully loaded magazine is a concern.
The strengths lie in the increased capacity and enhanced ergonomics for reloading. The main weakness is the reported difficulty of installation, which I experienced firsthand and the slight reduction in reliability. It generally meets expectations, but with caveats.
Design & Ergonomics
The build quality is excellent, with the anodized aluminum providing a solid and durable feel. The weight is noticeable, but not excessive. The extended ledge, while intended for improved grip, can be a bit sharp against the hand, especially during prolonged use.
There is a moderate learning curve. Getting used to the increased length and weight of the magazine requires some practice.
Durability & Maintenance
The Agency Arms Sig Sauer P320 9mm +5 Pistol Magazine Extension appears to be built to last. The anodized finish is resistant to scratches and wear. Maintenance is simple, requiring only occasional cleaning and lubrication of the magazine spring.
Accessories and Customization Options
The extension itself doesn’t come with any additional accessories. Customization options are limited to marking the dot matrix panel. The product is designed to be compatible with the Agency Arms X-Series Magwell and the factory Sig Sauer magwell, which is a significant advantage.
