Ruger 90643 Ruger LCP 380 Automatic Colt Pistol (ACP) 6 Rd Black Finish Review

Taking the Ruger 90643 Ruger LCP 380 Automatic Colt Pistol (ACP) 6 Rd Black Finish for a Spin

For years, my Ruger LCP has been a trusted companion, a discreet tool for self-reliance, and a testament to compact firearm design. As any seasoned owner knows, reliable magazines are the lifeblood of a semi-automatic pistol, ensuring those critical moments are met with function, not frustration. This is precisely why I found myself looking for replacements for my aging LCP magazines. The standard 6-round capacity, while compact, often means frequent reloads, and having a fresh, dependable supply is paramount. I needed something that would slot seamlessly into my EDC rotation without fuss.

My journey led me to the Ruger 90643 Ruger LCP 380 Automatic Colt Pistol (ACP) 6 Rd Black Finish magazine. While the idea of a simple steel magazine might seem mundane, I’ve learned that even the smallest components can make or break a firearm’s performance. My previous experiences with aftermarket magazines have been a mixed bag, with some performing admirably and others introducing feeding issues that eroded my confidence. Therefore, the allure of factory-produced parts, designed specifically for the LCP, was strong.

Upon receiving this pack of two magazines, my initial impression was one of familiar quality. The blued steel construction felt robust, with a satisfying heft that hinted at durability. The inclusion of an extended floorplate on each magazine was a welcome addition, promising a slightly improved grip and potentially aiding in magazine seating. It’s these small ergonomic considerations that, for me, distinguish a good part from a great one.

I had briefly considered generic, off-brand magazines due to their lower price point. However, the potential for unreliability in a firearm intended for personal defense is a gamble I’m rarely willing to take. The reputation of Ruger as a manufacturer lent a significant amount of confidence to this purchase. My first reaction upon seeing these magazines was a quiet satisfaction, a sense of having made a practical, sensible choice for a critical piece of equipment.

Real-World Testing: Putting Ruger 90643 Ruger LCP 380 Automatic Colt Pistol (ACP) 6 Rd Black Finish to the Test

First Use Experience

My testing grounds for this magazine pack were primarily the familiar environment of my local indoor shooting range and, more importantly, my personal defensive practice sessions at home, ensuring readiness in a controlled setting. I loaded both magazines to their 6-round capacity, a familiar process given my extensive history with the LCP. The extended floorplate offered a slightly more substantial grip than the flush-fit factory magazines I’d been using, which was immediately noticeable and appreciated during rapid reloads.

The initial range session involved cycling through dummy rounds to check for feeding issues before live fire. I then proceeded with live fire, focusing on consistent shooting drills. The magazines seated firmly into the pistol’s magazine well with a positive click. Throughout the initial magazine changes and subsequent firing strings, the extended floorplate proved beneficial, offering a better purchase for finger manipulation, particularly during timed drills.

However, it was during a more extended range session that a subtle difference emerged. One of the magazines, while visually identical to its counterpart, began to exhibit a slight hesitation during the last few rounds. It wasn’t a complete failure, but a barely perceptible pause in the feeding cycle that, to my experienced hand, signaled potential future issues. The other magazine, however, performed flawlessly throughout the entire session.

Extended Use & Reliability

After several weeks and hundreds of rounds cycled through these magazines, a distinct performance disparity became evident. One magazine, the one that showed the early signs of hesitation, started to manifest more pronounced fail-to-feed malfunctions. It seemed to hold the cartridges just a bit too tightly at the feed ramp, preventing the slide from stripping the top round cleanly on occasion. This occurred with different ammunition types, ruling out a batch issue with the .380 ACP rounds themselves.

The second magazine, on the other hand, continued to perform with the reliability I expect from factory Ruger components. It fed every round smoothly, seated consistently, and contributed to confident practice. This experience highlights a critical aspect of mass-produced goods: even within the same product line, minor manufacturing variations can have a significant impact on performance, especially in sensitive mechanisms like firearm magazines.

Maintenance has been straightforward, as expected with blued steel components. A quick wipe-down after range sessions and occasional light oiling have kept them free from rust and grime. However, the issue with one of the magazines did raise questions about long-term durability and consistency. My previous experiences with factory LCP magazines have generally been more uniformly positive, which made this particular anomaly stand out.

Breaking Down the Features of Ruger 90643 Ruger LCP 380 Automatic Colt Pistol (ACP) 6 Rd Black Finish

Specifications

• Manufacturer: Ruger
• Gun Make: Ruger
• Gun Model: Ruger LCP
• Caliber: .380 ACP
• Magazine Capacity: 6 Round
• Finish: Black
• Fabric/Material: Steel

These specifications translate directly into the functionality and feel of the magazine. The .380 ACP caliber dictates the size and shape of the cartridges the magazine is designed to hold. Its 6-round capacity is standard for the LCP, balancing a discreet profile with a reasonable number of rounds for its intended purpose. The black finish offers a degree of corrosion resistance and blends aesthetically with the firearm.

The use of steel as the primary material for the magazine body provides the necessary strength and durability to withstand repeated insertions, extractions, and the pressures associated with holding live ammunition. The inclusion of an extended floorplate, while not explicitly listed as a separate specification in some technical readouts, is a crucial design element affecting grip and handling. This floorplate also contributes to the overall length of the magazine, making it slightly easier to manipulate than a flush-fit option. It’s important to note that while this magazine fits the LCP II, it will not provide the last-round hold-open feature, a detail that is critical for users of that specific pistol model.

Performance & Functionality

When the Ruger 90643 Ruger LCP 380 Automatic Colt Pistol (ACP) 6 Rd Black Finish magazine is functioning as intended, its performance is solid. The 6-round capacity is perfectly adequate for the LCP’s role as a compact, easily concealable defensive pistol. Feeding is generally smooth, allowing the pistol to cycle reliably under normal conditions. The blued steel construction provides a good foundation for consistent feeding mechanics, assuming no manufacturing defects.

However, the performance is not without its caveats, as evidenced by my experience with one of the two magazines in the pack. The presence of a fail-to-feed malfunction indicates a potential issue with the internal dimensions or spring tension. This problem directly impacts the firearm’s primary function: delivering rounds reliably. While one magazine performed exceptionally well, the inconsistency in the pack is a significant weakness.

The price point for this two-pack of magazines, around $58.79, places it in a moderate category for firearm accessories. For a pair of factory magazines, this is generally a fair price, especially when they perform flawlessly. However, when one unit demonstrates a critical functional flaw, the value proposition diminishes considerably.

Design & Ergonomics

The design of the Ruger 90643 Ruger LCP 380 Automatic Colt Pistol (ACP) 6 Rd Black Finish is fundamentally sound, leveraging the established platform of the LCP. The steel construction feels robust, and the black finish is utilitarian and resists minor scratches well. The inclusion of an extended floorplate is a smart ergonomic choice.

This extended floorplate significantly improves the grip compared to standard flush-fit magazines. It allows for a more secure purchase during reloads, which can be crucial in high-stress situations. The shape of the floorplate is also designed to minimize snagging, a vital consideration for concealed carry.

The tactile feedback when seating the magazine is positive and distinct. You can feel and hear it lock into place, providing an essential confirmation for the shooter. However, the slight variation in manufacturing that led to the malfunction in one of the magazines is a design consideration that should ideally be addressed more consistently by the manufacturer.

Durability & Maintenance

Based on the material—blued steel—and the Ruger pedigree, one would expect good durability from these magazines. The 6-round capacity means the spring is not under excessive compression for extended periods, which can help prolong its lifespan. The black finish offers a degree of protection against rust, though it’s always advisable to keep steel magazines dry and clean.

Maintenance is minimal; a simple wipe-down with a cloth after use and an occasional application of a light gun oil are sufficient for routine care. Disassembly for cleaning the spring and follower is also straightforward, allowing for thorough maintenance if needed. However, the premature onset of malfunctions in one of the magazines raises concerns about the consistency of durability across units. While the materials suggest longevity, a functional defect can negate that potential quickly.

There are no complex parts or delicate mechanisms that would typically fail under normal use, beyond the spring and follower, which are standard wear items. The primary concern here is not so much wear and tear as it is potential manufacturing inconsistencies that could lead to premature failure of functionality, rather than structural integrity.

Accessories and Customization Options

These magazines are designed specifically for the Ruger LCP and, as such, are not typically subject to extensive customization. The primary “accessory” feature integrated into this specific model is the extended floorplate. This is a deliberate design choice by Ruger to enhance user ergonomics, offering a better grip for magazine changes.

There are no other integrated accessories or user-replaceable parts beyond the standard spring and follower, which are typical for most firearm magazines. Compatibility is limited to the Ruger LCP and, with the noted caveat about last-round hold-open, the LCP II. Unlike some modular firearm components, these magazines are a self-contained unit, meant to perform their function as-is.
