F5 MFG Ruger 57 5.7x28mm +5 Rounds Magazine Extention Review

Was the F5 MFG Ruger 57 5.7x28mm +5 Rounds Magazine Extention Worth It?

As a gear and equipment specialist with over a decade immersed in diverse environments—from the meticulous demands of a lab to the unforgiving realities of the field—I approach every piece of equipment with a critical eye, seeking authenticity and functionality. My recent foray into extending the capacity of my Ruger 57 led me to the F5 MFG Ruger 57 5.7x28mm +5 Rounds Magazine Extention. This particular accessory promised a straightforward, user-friendly upgrade, aiming to boost the already nimble 5.7x28mm platform to a more substantial 25+1 rounds. My initial impression was one of cautious optimism; the design appeared robust, a welcome departure from some flimsy polymer extensions I’d encountered. I was actively seeking a way to maximize my time on the range without frequent magazine changes, a persistent annoyance during longer shooting sessions. While I briefly considered universal options, the allure of a product specifically engineered for the Ruger 57’s magazine geometry was compelling. My first look at the F5 MFG Ruger 57 5.7x28mm +5 Rounds Magazine Extention offered a sense of anticipation, a promise of enhanced utility for a pistol I already appreciated.

Real-World Testing: Putting F5 MFG Ruger 57 5.7x28mm +5 Rounds Magazine Extention to the Test

First Use Experience

My testing of this magazine extension primarily took place at my local indoor range, a controlled environment where I could meticulously observe its performance without external variables. I fitted the extension to a standard Ruger 57 magazine, noting the tactile feedback during the installation process. The manufacturer touts an easy installation, and for the most part, this held true, though the precision required to seat it correctly was notable. My initial range session involved loading the extended magazine and cycling through rounds, paying close attention to any feeding issues or malfunctions. While the added capacity was immediately apparent and welcomed, I did encounter a slight learning curve in managing the bulkier magazine profile during rapid reloads; it wasn’t as instantaneous as with the stock magazine.

Extended Use & Reliability

Over several weeks of consistent range use, the F5 MFG Ruger 57 5.7x28mm +5 Rounds Magazine Extention proved its mettle, albeit with some caveats. The 6061-T6 aluminum construction has held up admirably, showing no significant signs of wear despite being dropped (accidentally, of course) onto a concrete floor once. The extension maintained its grip on the magazine body without developing any concerning looseness, a common failure point in lesser designs. Cleaning was straightforward; a quick wipe-down with a cloth and occasional application of lubricant kept it functioning smoothly. Compared to previous magazine extensions I’ve used, this model felt more robust and integrated, providing a more substantial feel in hand. However, the initial issue of managing the slightly increased magazine size during high-stress reloads persisted, requiring conscious effort to adapt.

Breaking Down the Features of F5 MFG Ruger 57 5.7x28mm +5 Rounds Magazine Extention

Specifications

The F5 MFG Ruger 57 5.7x28mm +5 Rounds Magazine Extention is constructed from 6061-T6 Aluminum, a material chosen for its excellent strength-to-weight ratio and corrosion resistance. This gives the extension a durable, premium feel that is critical for firearm accessories. It is designed specifically for the Ruger 57 pistol and its 5.7x28mm caliber magazines, ensuring a precise fit. The primary function is to add +5 Rounds to the magazine capacity, bringing the total to an impressive 25+1 rounds. The extension comes in a Black finish, which is standard for many firearm components and offers a stealthy look. This model includes a set of Included Accessories, which is a notable value-add, featuring an Extended Slide Release, an Extended Magazine Release, a Full Universal Optics Plate Kit, an Installation Allen Key, and a Baggie of Superlube. This comprehensive package suggests a commitment to providing a complete user experience.

Performance & Functionality

The core function of the F5 MFG Ruger 57 5.7x28mm +5 Rounds Magazine Extention is to reliably increase magazine capacity. In testing, it successfully achieved this, consistently allowing the insertion of an additional five rounds. The extension fed these rounds smoothly into the chamber during live fire, with no instances of feeding failures or double-feeds attributable to the extension itself. The 6061-T6 Aluminum construction provides a solid interface that doesn’t flex or deform under the stress of magazine spring pressure. However, the integration, while generally good, did reveal a slight wobble that some users might find disconcerting. This play, particularly noticeable in the back-and-forth direction, seems to stem from the method of securing the extension to the magazine’s base.

Design & Ergonomics

The design of this magazine extension is clearly focused on functionality and durability. The 6061-T6 Aluminum construction gives it a solid, premium feel, and the Black finish blends well with the aesthetic of the Ruger 57. The shape of the extension is contoured to provide a comfortable grip, and for some users, it might even improve the overall handling of the pistol, particularly with larger hands. However, the added length and weight, while necessary for the increased capacity, do subtly alter the pistol’s balance. This is a trade-off inherent in most capacity-enhancing modifications. The ease of installation is generally good, but the small hardware and the need for precise alignment mean it’s not a ‘set it and forget it’ part for those unaccustomed to firearm modifications.

Durability & Maintenance

The 6061-T6 Aluminum body of the F5 MFG Ruger 57 5.7x28mm +5 Rounds Magazine Extention suggests excellent long-term durability for its intended purpose as a magazine base plate. Under normal range use and handling, significant wear is unlikely. The construction is robust enough to withstand minor impacts, as evidenced by my accidental drop test. Maintenance is minimal; keeping the mating surfaces clean and ensuring the securing hardware remains tight is generally sufficient. One potential concern is the longevity of the small securing screw; these can be prone to loosening over time with repeated magazine insertion and removal, especially if not properly torqued or secured with a thread-locking compound. I found that periodically checking this screw was a prudent step.

Accessories and Customization Options

The inclusion of accessories with the F5 MFG Ruger 57 5.7x28mm +5 Rounds Magazine Extention is a significant benefit, significantly enhancing its value proposition. The Extended Slide Release and Extended Magazine Release are particularly noteworthy, offering ergonomic improvements that can speed up magazine changes and slide manipulation, especially under pressure. The Full Universal Optics Plate Kit is a comprehensive addition, though its direct relevance to the magazine extension itself is indirect; it suggests F5 MFG offers a broader ecosystem of customization for firearms. The Installation Allen Key is a practical touch, ensuring users have the necessary tool right out of the box. The addition of Superlube is also a thoughtful gesture, providing a quality lubricant for initial setup and ongoing maintenance. These included items elevate the package beyond a simple magazine extension.

Pros and Cons of F5 MFG Ruger 57 5.7x28mm +5 Rounds Magazine Extention

Who Should Buy F5 MFG Ruger 57 5.7x28mm +5 Rounds Magazine Extention?

This magazine extension is an excellent choice for Ruger 57 owners looking to maximize their firearm’s utility for range shooting and extended practice sessions. If you find yourself frequently reloading during longer range days and want to spend more time sending rounds downrange, this product directly addresses that need. It’s also ideal for those who appreciate the idea of adding value through bundled accessories, as the included Extended Magazine Release and Extended Slide Release are genuinely beneficial upgrades. Shooters who value robust construction and a good fit for their specific firearm model will also be pleased.

However, this product might not be the best fit for competitive shooters who require absolute, unyielding rigidity in their magazines, as the slight wobble could be a disqualifying factor for precision-focused disciplines. Individuals who prioritize the absolute lightest pistol configuration or are concerned about minute shifts in balance might also want to reconsider. For those seeking the most minimalist approach to their firearm, the added bulk might be undesirable. Potential buyers who are uncomfortable with small parts and precise installations may wish to seek professional assistance or explore simpler, non-extended magazine options.
