Cross Armory Weighted Base Plate +0 Magazine Extension Review

Deep Dive into the Cross Armory Weighted Base Plate +0 Magazine Extension

For those who carry firearms for self-defense or competition, magazine reliability and ease of manipulation under stress are paramount. Over time, I’ve found that even minor enhancements can make a significant difference in critical situations. This led me to seek out upgrades for my Glock magazines, specifically something that could aid in seating the magazine and potentially help with extraction if needed, without adding unwanted bulk. I came across the Cross Armory Weighted Base Plate +0 Magazine Extension, and its design promises to address some common pain points.

The primary driver for this purchase was the desire for a more robust grip point on my magazines. My previous magazine extensions were functional but lacked any real texture or shape that would provide confidence if my hands were compromised by sweat, blood, or gloves. The Cross Armory Weighted Base Plate +0 Magazine Extension explicitly addresses this with its “True Grip” design, featuring engineered slots with 90-degree angled ledges. I also noted the manufacturer’s claim of the slimmest profile and lightest weight, which immediately piqued my interest given the often-bulky nature of many aftermarket accessories. I had considered a few other popular brands, but their bulkier designs and sometimes complex installation methods deterred me. My first impression upon receiving this extension was one of solid craftsmanship; the aircraft-grade aluminum felt substantial, and the machining was precise, giving me a sense of confidence in its potential durability.

Real-World Testing: Putting Cross Armory Weighted Base Plate +0 Magazine Extension to the Test

First Use Experience

My initial testing ground for the Cross Armory extension was my usual range day environment. I installed the extension on a few of my standard Glock 9mm magazines. The installation process itself was remarkably straightforward, which was a pleasant change from some other accessories I’ve fitted over the years. I focused on rapid magazine changes, both deliberate and simulated under mild duress, drawing from a holster and executing controlled reloads.

During these drills, the extension performed admirably. The added weight, though minimal, felt balanced and didn’t detract from the overall feel of the magazine. The “True Grip” slots offered a discernible purchase, even when I intentionally made my hands slightly damp with water to simulate a common field condition. I experienced no snags on my magazine pouch or during the seating process into the firearm’s magwell. The slimmest profile claim also held true; the magazines still fit comfortably within my standard Glock holster without any adjustment or binding.

Extended Use & Reliability

After several weeks of consistent use, including multiple range sessions and carrying the magazines loaded in my everyday attire, the Cross Armory Weighted Base Plate +0 Magazine Extension has proven its mettle. The aluminum construction has resisted the usual scuffs and scrapes one might expect from constant insertion into pouches and the magwell. There have been no signs of cracking or deformation, even after a few instances where a magazine was dropped onto the concrete floor during a fast-paced drill.

Maintenance has been a non-issue. A quick wipe-down with a cloth is all that’s needed to keep the extension clean, and the simple screw retention mechanism means I haven’t had to worry about intricate locking tabs or springs. Compared to some polymer extensions I’ve used in the past that would loosen or crack, this all-aluminum offering feels far more robust. It has maintained its “True Grip” functionality throughout, with the angled ledges providing a consistent point of contact for my fingers.

Breaking Down the Features of Cross Armory Weighted Base Plate +0 Magazine Extension

Specifications

The Cross Armory Weighted Base Plate +0 Magazine Extension is constructed from Aircraft Grade CNC Aluminum, a choice that immediately speaks to its intended durability and a desire to reduce weight where possible without sacrificing strength. It’s designed as a +0 Round capacity extension, meaning it does not increase the ammunition capacity of the magazine, but rather serves to improve handling and reliability. This makes it 50 state legal and suitable for various competitive shooting disciplines that may have magazine capacity restrictions.

The extension is engineered to fit Glock Brand or Glock clone magazines across various generations, specifically listed for Models 5, 4, 3, 2, and 1. This broad compatibility is a significant advantage for Glock owners. A key specification highlighted is its 1.35oz weight, which the manufacturer claims makes it the lightest weight and slimmest profile, all aluminum, magazine extension in the industry. This weight, combined with the design, adds just enough mass to aid magazine seating and extraction without making the magazine feel overly cumbersome. The slimmest profile is crucial for ensuring it fits within standard magwells and holsters, avoiding the bulk that can impede weapon manipulation or concealment.

Performance & Functionality

The core function of a magazine extension is to provide a better surface for seating and, potentially, extracting a magazine. The Cross Armory Weighted Base Plate +0 Magazine Extension excels in this regard. The “True Grip” feature, with its precisely angled ledges, provides a substantial and reliable point of contact. This is invaluable during a reload, especially under stress or when wearing gloves; I found I could get a much more positive and secure grip on the magazine base than with my previous extensions.

Its ability to aid in extraction if a magazine becomes stuck is also a significant benefit. The engineered bite of the slots offers a purchase that feels much more secure than a smooth surface or simple texturing. In terms of meeting expectations, this extension certainly exceeds them. The slimmest profile is not just marketing; it genuinely integrates seamlessly with the Glock magazine without causing interference issues.

Design & Ergonomics

The design of the Cross Armory Weighted Base Plate +0 Magazine Extension is a clear standout. The focus on a slimmest profile is evident, keeping the overall dimensions comparable to the factory Glock base plate, but with added functionality. The machined aluminum provides a premium feel, and the CNC machining ensures tight tolerances and a clean finish. The True Grip slots are thoughtfully designed; they are aggressive enough to provide excellent purchase but are shaped to avoid snagging on clothing or gear, a critical consideration for concealed carry or tactical applications.

Ergonomically, the extension feels like a natural extension of the magazine itself. The weight distribution is balanced, and the added length is subtle, not making the magazine unwieldy. Installation is arguably one of its strongest ergonomic points; the simple screw-based retention system is a breath of fresh air compared to more complex designs. This ease of use minimizes potential frustration and ensures the user can quickly and reliably install or remove the extension if needed.

Durability & Maintenance

Given its Aircraft Grade CNC Aluminum construction, the durability of the Cross Armory Weighted Base Plate +0 Magazine Extension is exceptional for its intended purpose. Aluminum is inherently resistant to corrosion and deformation under typical use conditions for firearms accessories. I have experienced no chipping, peeling, or significant wear after repeated drops and magazine changes.

Maintenance is virtually non-existent. The smooth, machined surface is easy to wipe clean of dust, debris, or residual lubricant. The retention screw, with its simple design, is unlikely to fail or loosen under normal recoil and handling. Unlike some polymer extensions that can become brittle over time or crack under impact, this metal extension offers a much longer service life.

Accessories and Customization Options

The Cross Armory Weighted Base Plate +0 Magazine Extension is designed for simplicity, and as such, it doesn’t come bundled with a wide array of accessories. The primary “accessory” is, of course, the extension itself and the single screw used for its retention. The beauty of this product lies in its direct functionality and its ability to integrate seamlessly with existing gear.

While the extension itself isn’t designed for further customization, its design encourages compatibility. The slimmest profile ensures it works with a vast majority of Glock-compatible magazine pouches and holsters. This means users don’t need to purchase specialized pouches or modify existing ones to accommodate the extension, which is a significant advantage. The 0 round capacity also means it aligns with regulations for competitive shooting, allowing for broader application without needing alternative magazine bodies.

Pros and Cons of Cross Armory Weighted Base Plate +0 Magazine Extension

The Cross Armory Weighted Base Plate +0 Magazine Extension is an ideal upgrade for any Glock owner who prioritizes reliable magazine handling and a positive grip under all conditions.

Individuals who are looking to increase their magazine’s ammunition capacity should look elsewhere, as this is strictly a +0 design. Furthermore, those who prefer lighter-weight polymer accessories might find the aluminum construction slightly heavier than expected, although it remains one of the lightest metal options available.

A good magazine pouch that allows for a consistent draw is a complementary item that will further enhance the utility of this extension.
