Warne Smith & Wesson M&P 9/40 Extended Magazine Base Pad Review

The Warne Smith & Wesson M&P 9/40 Extended Magazine Base Pad: First Use to Final Thoughts

As someone who spends a significant amount of time with firearms, reliability and efficiency are paramount. My Smith & Wesson M&P pistols are workhorses, but like any tool, sometimes an upgrade can make a noticeable difference. My search for improved magazine management led me to the Warne Smith & Wesson M&P 9/40 Extended Magazine Base Pad. This seemingly small component promised to enhance my ammo handling, and as an experienced gear enthusiast, I was eager to see if it lived up to the hype. Before acquiring this particular model, I’d considered a few generic polymer extensions, but their perceived flimsiness and lack of specific design features made me pause. My initial impression upon receiving the Warne base pads was one of solid craftsmanship. They felt substantial, immediately suggesting a product built to last, and offered a welcome sense of relief that a potential frustration point had been addressed with quality.

Real-World Testing: Putting **Warne Smith & Wesson M&P 9/40 Extended Magazine Base Pad** to the Test

First Use Experience

My first encounter with the Warne Smith & Wesson M&P 9/40 Extended Magazine Base Pad was in my home workshop. The installation process itself was straightforward, requiring only the provided Torx screw and a small screwdriver. I immediately fitted one onto a spare M&P 9 magazine, ensuring the fit was snug and secure.

The initial test was practical: loading and unloading magazines at my workbench. The added grip surface was immediately noticeable, making it easier to seat magazines firmly and extract them cleanly, even with slightly greasy hands from other tasks. This small improvement eased a minor but persistent annoyance.

I then took the magazines equipped with these base pads to the indoor range for live-fire testing. During rapid magazine changes under pressure, the extended grip was a definite advantage. It provided a tactile reference point, allowing for quicker acquisition and a more confident pull when dropping or seating magazines.

I also subjected one of the magazines to a minor drop test on the concrete floor of my garage. The aluminum construction held up admirably, showing only a faint scuff mark with no compromise to its structural integrity. This was a reassuring sign for its durability in less controlled environments.

Extended Use & Reliability

After several weeks of regular range trips and consistent use in my workshop, the Warne Smith & Wesson M&P 9/40 Extended Magazine Base Pad has proven its mettle. The Type II hard-coat anodized aluminum finish shows no signs of significant wear, resisting scratches and scuffs from routine handling. I have found no issues with the retention screw loosening over time, which speaks to the quality of the hardware and the design’s stability.

Maintenance has been minimal, essentially just an occasional wipe-down along with the standard magazine cleaning. The ergonomic finger grooves, while subtle, continue to provide a consistent and improved grip, especially when performing emergency reloads. Compared to the plastic extensions I’ve used or seen on other firearms, these metal pads feel significantly more robust and less prone to breakage.

They have performed flawlessly across different ammunition types, without any impact on feeding reliability. The added weight is negligible, and it has not negatively affected the balance or handling of the firearm. It’s the kind of reliable, unobtrusive upgrade that simply works, day in and day out.

Breaking Down the Features of **Warne Smith & Wesson M&P 9/40 Extended Magazine Base Pad**

Specifications

The Warne Smith & Wesson M&P 9/40 Extended Magazine Base Pad is constructed from 6061-T6 Aluminum. This aerospace-grade aluminum alloy is chosen for its excellent strength-to-weight ratio, making the pad durable without adding excessive bulk. The finish is a Type II Hardcoat Anodized treatment, which provides superior resistance to corrosion and wear, crucial for a component subjected to frequent handling and potential impacts.

While the product description states “0 Round” for magazine capacity, this refers to the base pad itself not adding rounds but rather enhancing the grip and handling of the existing magazine. These extensions are specifically designed for the Smith & Wesson M&P 40 and Smith & Wesson M&P 9 pistol models. They are engineered to accommodate the standard magazine capacity for these firearms, offering a more secure grip and potentially aiding in faster magazine changes.

The included hardware is a Torx head screw and washer for reliable retention. The Torx head ensures a secure engagement that is less prone to stripping than Phillips head screws, and the washer distributes the clamping force effectively. The caliber specification of .355 Caliber accurately reflects its compatibility with 9mm ammunition (.355 inches).

Performance & Functionality

In terms of its primary function, the Warne Smith & Wesson M&P 9/40 Extended Magazine Base Pad excels at enhancing magazine manipulation. The most significant performance boost comes from the improved grip. The machined finger grooves offer a secure purchase, making it easier to grasp and smoothly draw a magazine from a pouch or directly from the firearm.

This enhanced grip directly translates to faster and more confident magazine changes during drills or actual use. The added surface area also makes it more intuitive to seat a fresh magazine firmly, ensuring it locks into place reliably. While it doesn’t increase the round count, it undeniably improves the efficiency of managing the ammunition you already have.

The main job of this base pad is to improve ergonomics for magazine handling, and it performs this task exceptionally well. Its only “weakness” is that it is a dedicated component; it doesn’t offer multi-functionality beyond its core purpose. However, within its intended role, it is a highly effective enhancement.

Design & Ergonomics

The design of the Warne Smith & Wesson M&P 9/40 Extended Magazine Base Pad is both functional and aesthetically pleasing. Machined from aluminum, it possesses a solid, premium feel that is a significant upgrade from most factory polymer base plates. The Type II Hardcoat Anodized finish provides a subtle matte look that complements the firearm’s existing finish.

Ergonomically, the prominent finger grooves are well-placed and provide excellent tactile feedback. They offer a secure grip even when hands are sweaty or gloved, which is crucial for reliable magazine changes. The overall shape integrates smoothly with the magazine body, avoiding any awkward protrusions or sharp edges that could snag on clothing or pouches.

The fit onto the magazine is precise, with no wobble or looseness. This speaks to the quality of the machining and the tight tolerances Warne maintains. The inclusion of a dedicated Torx screw for attachment ensures a secure lock-up that feels permanent once installed.

Durability & Maintenance

Given its 6061-T6 Aluminum construction and Type II Hardcoat Anodized finish, the durability of the Warne Smith & Wesson M&P 9/40 Extended Magazine Base Pad is expected to be very high for its intended purpose. Under normal handling and range use, I anticipate it will last the lifetime of the magazines it is attached to. The anodizing is a robust finish that resists abrasion and corrosion effectively.

Maintenance is virtually non-existent. The material and finish are resistant to common gun cleaning solvents and oils. Any dirt or debris can be easily wiped away with a cloth. Unlike polymer extensions that can degrade or become brittle over time, this aluminum pad should maintain its structural integrity indefinitely.

The only potential point of failure would be the retention screw, but its Torx head and the quality of the threading suggest it will hold up well. Regular checks for tightness are always a good practice, but I haven’t found it necessary to tighten them after initial installation.

Accessories and Customization Options

The Warne Smith & Wesson M&P 9/40 Extended Magazine Base Pad comes with its essential hardware: a Torx head screw and washer. These are crucial for securing the base pad to the magazine and are designed for a reliable and strong connection. No other accessories are typically included or necessary for its function.

This product is not designed for extensive customization in terms of adding other components. Its purpose is to enhance the existing magazine. However, Warne offers these base pads for various firearm models, meaning one could potentially standardize on Warne extensions across different platforms if available. The primary “customization” is choosing to install it on your M&P magazines in the first place.

Pros and Cons of **Warne Smith & Wesson M&P 9/40 Extended Magazine Base Pad**

Who Should Buy **Warne Smith & Wesson M&P 9/40 Extended Magazine Base Pad**?

The Warne Smith & Wesson M&P 9/40 Extended Magazine Base Pad is an excellent choice for M&P pistol owners who prioritize enhanced magazine handling and durability. This includes competitive shooters who need fast, reliable magazine changes, as well as firearms enthusiasts who appreciate high-quality, robust accessories for their EDC (Everyday Carry) or range guns. If you find yourself fumbling for magazine releases or wanting a more positive grip on your magazines, this upgrade is highly beneficial.

Those who should likely skip this product are individuals looking to increase their magazine’s round count, as this pad does not add capacity. If you are on an extremely tight budget and only need a basic grip extension, cheaper polymer options might suffice, although they often lack the durability and refined ergonomics of this aluminum model. For users of other pistol platforms not supported by Warne, this specific product would not be applicable.

For an even more optimized experience, consider pairing these base pads with quality magazine pouches that offer easy access and retention. Keeping your magazines clean and well-maintained will also ensure they work seamlessly with the enhanced grip provided by the Warne extensions.
