Let’s Dive into Pro Mag Springfield XD-9 Plus 4 / XD-40 Plus 3 Magazine Extension
The Pro Mag Springfield XD-9 Plus 4 / XD-40 Plus 3 Magazine Extension promises to boost your Springfield XD’s capacity, offering a tactical edge and enhanced firepower. Pro Mag is a well-known manufacturer, but their accessories often spark debate regarding reliability, so I approached this product with a mix of curiosity and skepticism. Does this extension live up to the hype, or is it just another range toy?
I’ve always been a believer in maximizing capacity within legal limits, especially for defensive purposes. The limited capacity of some factory magazines felt like a handicap, prompting my search for a reliable extension. The initial impression upon unboxing was surprisingly positive; the extension felt solid, although lighter than the factory magazine base.
I considered extensions from other brands like Pearce Grips and Strike Industries, but Pro Mag’s significantly lower price point swayed my decision, despite the mixed reviews. My first impression was cautiously optimistic – it seemed like a decent product, but the real test would be on the range. It’s always a gamble in the aftermarket space.
Real-World Testing: Putting Pro Mag Springfield XD-9 Plus 4 / XD-40 Plus 3 Magazine Extension to the Test
First Use Experience
I took the Pro Mag Springfield XD-9 Plus 4 / XD-40 Plus 3 Magazine Extension to my local outdoor shooting range on a typical Southern California day – sunny and dry. I tested it in my Springfield XD-9, using a variety of ammunition types, from standard 115-grain FMJ to heavier 147-grain hollow points. The installation was simple, just requiring popping off the factory base plate and sliding this one on.
The first few magazines fed flawlessly, but I quickly encountered issues: failures to feed after the fifth or sixth round, specifically with the extension installed. These malfunctions didn’t occur with the factory magazine, suggesting the extension was the culprit. The magazine spring seemed to struggle with the increased capacity, especially under rapid fire.
Extended Use & Reliability
After several range sessions, the Pro Mag Springfield XD-9 Plus 4 / XD-40 Plus 3 Magazine Extension continued to be inconsistent. Sometimes it worked perfectly, other times it caused failures to feed or even stovepipes, making it unreliable for serious use. I noticed some wear on the extension’s polymer body after about a month of use, mainly scuff marks from magazine changes and dropping it on the hard-packed range surface.
Cleaning and maintaining the extension was straightforward – a quick wipe-down with a cloth and some CLP was all it needed. Compared to my experience with other magazine extensions (like those from Magpul, which are rock solid), the Pro Mag fell short in terms of reliability and durability. It definitely disappoints me.
Breaking Down the Features of Pro Mag Springfield XD-9 Plus 4 / XD-40 Plus 3 Magazine Extension
Specifications
The Pro Mag Springfield XD-9 Plus 4 / XD-40 Plus 3 Magazine Extension is designed to increase the capacity of Springfield XD-9 and XD-40 magazines. Specifically, it claims to add +4 rounds to XD-9 magazines and +3 rounds to XD-40 magazines. The extension is constructed from a polymer body with a steel locking plate.
The manufacturer, Pro Mag, lists the product condition as “New”. The listed magazine capacity is “3 Round,” although real-world testing and user feedback suggest varying results. The polymer construction keeps the weight down.
Performance & Functionality
The primary function of the Pro Mag Springfield XD-9 Plus 4 / XD-40 Plus 3 Magazine Extension is to increase magazine capacity, but its performance is inconsistent. While some users report flawless operation and achieving the advertised capacity, others, including myself, experienced failures to feed and reduced capacity. This inconsistency makes it unreliable for tactical or defensive applications.
The extension’s strength is its ease of installation and relatively low cost. Its weakness is the questionable reliability and potential for malfunctions. In my experience, it only partially meets expectations due to its performance issues.
Design & Ergonomics
The Pro Mag Springfield XD-9 Plus 4 / XD-40 Plus 3 Magazine Extension is designed to seamlessly integrate with the Springfield XD’s grip, providing a comfortable and ergonomic feel. The polymer construction keeps the weight down, making it easy to carry and handle. There’s no significant learning curve; simply install and use.
The build quality is acceptable for the price point, but the polymer material feels less robust than the factory magazine base. The weight is negligibly different from the OEM baseplate.
Durability & Maintenance
The durability of the Pro Mag Springfield XD-9 Plus 4 / XD-40 Plus 3 Magazine Extension is a concern, especially under heavy use. The polymer body is susceptible to scratches and scuffs, and the internal spring may weaken over time, leading to feeding issues. Maintenance is easy, requiring only occasional cleaning with a cloth and some lubricant.
The longevity of the extension is questionable, particularly if subjected to frequent magazine changes and rough handling. I anticipate replacing them eventually due to wear and tear.
Accessories and Customization Options
The Pro Mag Springfield XD-9 Plus 4 / XD-40 Plus 3 Magazine Extension doesn’t come with any additional accessories. There are no customization options available for this product, such as different colors or textures. It’s designed to be a straightforward, drop-in replacement for the factory magazine base.
This extension is generally compatible with standard Springfield XD magazines. However, compatibility with aftermarket followers may vary.
