Strike Industries SIG Sauer P320, 9mm, 5-Round Extended Magazine Plate Review

First Impressions of Strike Industries SIG Sauer P320, 9mm, 5-Round Extended Magazine Plate

The Strike Industries SIG Sauer P320, 9mm, 5-Round Extended Magazine Plate promises to boost the capacity of your P320 magazines while maintaining a sleek profile. As someone who’s spent years fiddling with magazine extensions, I was eager to see if this one lived up to the hype, especially considering the mixed user feedback regarding capacity. I wanted to see if it could deliver on the promised 5-round increase without sacrificing reliability or ease of use.

My concealed carry P320 X-Compact felt a little light on ammo with just the 15-round mags. I wanted that extra bit of capacity, especially considering the current climate. Several other extended magazine plates were available, but Strike Industries has a reputation for quality and aggressive aesthetics, so they won out.

Upon unboxing, the aluminum construction immediately impressed me; the Strike Industries plate felt solid and well-machined. The anodized finish looked clean, and the overall design seemed like it would blend well with the P320’s ergonomics. While some extensions look clunky and out of place, this one seemed promising in terms of aesthetics and slimness. My initial impression was cautiously optimistic, leaning towards excitement – but the real test would be on the range.

Real-World Testing: Putting Strike Industries SIG Sauer P320, 9mm, 5-Round Extended Magazine Plate to the Test

First Use Experience

I headed to my local indoor range with a few P320 17-round magazines to test the Strike Industries SIG Sauer P320, 9mm, 5-Round Extended Magazine Plate. Installation was a breeze; the instructions were clear, and the adaptable design allowed it to fit snugly onto the magazines. I spent about two hours at the range, running drills and practicing reloads with the extended magazines.

The first magazine loaded with the extended plate was difficult to get that last fifth round in. Once loaded, the magazine seated positively in my P320. During rapid-fire drills, the extended magazines performed admirably, with no malfunctions directly attributable to the Strike Industries plate.

Extended Use & Reliability

After several range sessions spanning a couple of months, the Strike Industries SIG Sauer P320, 9mm, 5-Round Extended Magazine Plate has held up relatively well. There is some minor wear on the anodized finish, particularly at the edges, but this is purely cosmetic. I did, however, confirm the common user complaint about only being able to reliably load 3-4 additional rounds in many of my magazines.

Maintenance is simple; a quick wipe down with a cloth is usually sufficient. While I haven’t experienced any failures to feed or other malfunctions, I’ve made it a habit to regularly inspect the plates and magazine springs for any signs of damage or wear. Compared to other magazine extensions I’ve used in the past, the Strike Industries plate seems more durable and less prone to cracking or bending.

Breaking Down the Features of Strike Industries SIG Sauer P320, 9mm, 5-Round Extended Magazine Plate

Specifications

The Strike Industries SIG Sauer P320, 9mm, 5-Round Extended Magazine Plate is designed to work with 21, 17, and 15-round SIG Sauer P320 magazines. It adds a claimed +5 rounds in 9mm. The plate is machined from 6061-T6 aluminum, weighing in at 1.97oz. Its dimensions comply with USPSA rules, making it suitable for competitive shooting.

The use of 6061-T6 aluminum ensures durability and resistance to corrosion, crucial for a part that will be exposed to the elements and potentially harsh conditions. The weight is also a key factor; too much weight can negatively impact the balance of the pistol, while too little might compromise the plate’s strength.

Performance & Functionality

The Strike Industries SIG Sauer P320, 9mm, 5-Round Extended Magazine Plate mostly delivers on its promise of increased capacity and improved ergonomics. While achieving a full +5 rounds can be difficult depending on the magazine, even the +3 or +4 I was able to reliably achieve is a welcome addition. The low-drag, no-snag design is genuinely effective, preventing the magazine from catching on clothing or gear during reloads.

The biggest weakness is the slight inconsistency in capacity; some magazines seem to accept the full +5 rounds, while others struggle with even +4. Overall, it meets most of my expectations.

Design & Ergonomics

The Strike Industries SIG Sauer P320, 9mm, 5-Round Extended Magazine Plate boasts impressive build quality, crafted from durable aluminum with a sleek anodized finish. Its weight is balanced, adding minimal bulk to the magazine. The slim profile of the plate enhances grip ergonomics, providing a comfortable and secure hold.

It is incredibly user-friendly. The installation process is straightforward, and the design seamlessly integrates with the P320’s aesthetics.

Durability & Maintenance

The Strike Industries SIG Sauer P320, 9mm, 5-Round Extended Magazine Plate is built to last, constructed from high-quality materials that withstand regular use and exposure to the elements. With proper care, it should maintain its structural integrity for years. Maintenance is a breeze, requiring only occasional cleaning to remove dirt and debris.

Accessories and Customization Options

The Strike Industries SIG Sauer P320, 9mm, 5-Round Extended Magazine Plate doesn’t come with additional accessories beyond the plate itself. However, its compatibility with standard P320 magazines allows for a range of customization options, such as swapping out magazine springs for improved feeding reliability. It’s worth noting that the plate is designed to work seamlessly with most aftermarket magazine wells designed for the P320.
