Glock G17 Magazine Spring, Not G43 Review

Discovering the Glock G17 Magazine Spring, Not G43: My Take

When a critical component of a firearm starts showing signs of wear, the immediate instinct is to find a reliable replacement. For me, that meant sourcing a new magazine spring for my Glock 17. The Glock G17 Magazine Spring, Not G43 from Glock is an OEM replacement, designed specifically for the G17 model.

My previous spring had endured thousands of rounds, countless magazine changes, and the general wear and tear of regular range days and competitive shooting. It had started to exhibit a slight decrease in ejection reliability, occasionally causing a weak feed or a failure to seat the last round correctly. This is not a catastrophic failure, but it’s enough to make you question the gun’s readiness for serious use.

Upon receiving the Glock G17 Magazine Spring, Not G43, my first impression was one of familiarity and quality. It felt robust, with that distinct, slightly oily feel of a new, precision-made Glock part. It’s a simple part, a coiled piece of metal, but its importance in magazine function is paramount.

I briefly considered aftermarket universal springs, but for critical components like magazine springs, sticking with OEM from the manufacturer, Glock, instills a greater sense of confidence. The price point is also remarkably accessible, making the decision to go OEM an easy one. My initial feeling was one of immediate relief, knowing I had a fresh, factory-spec part to restore the optimal performance of my magazines.

Real-World Testing: Putting Glock G17 Magazine Spring, Not G43 to the Test

First Use Experience

My testing primarily occurred at my local indoor and outdoor shooting ranges, as well as during training drills at my private property. The replacement spring was installed into a standard Glock 17 9mm magazine, a workhorse that sees frequent use. Conditions varied from dry, dusty outdoor ranges to the climate-controlled indoor environment.

The performance was immediately noticeable. Rounds fed smoothly and consistently, with no hesitation, even with the magazine loaded to its full capacity. This new spring provided a firmer push against the follower, ensuring that each round was presented to the chamber with proper tension.

Ease of installation was, as expected with Glock components, highly intuitive. If you can disassemble a Glock magazine, replacing the spring is a straightforward process. There were no surprises or quirks; the new spring simply did its job as intended from the very first load.

Extended Use & Reliability

After several weeks of consistent use, accumulating approximately 1,500 rounds through magazines fitted with this spring, its reliability has been unwavering. It has been subjected to rapid fire drills, extended sessions on the bench, and has sat loaded for days at a time without any discernible loss in tension or performance.

Durability is where OEM parts often shine, and this spring is no exception. There are no signs of premature fatigue, deformation, or any degradation in its springiness. It retains its original tension, which is crucial for consistent feeding.

Maintenance is minimal, as is typical for Glock magazine springs. A quick wipe-down with a cleaning cloth and a light application of lubricant (if desired) are sufficient. The primary care is ensuring the magazine itself is clean and free of debris, which the spring helps to eject effectively.

Comparing it to my previous, worn-out OEM spring, the difference is night and day. It’s also superior to the generic, budget aftermarket springs I’ve tried in the past, which often lose their tension far sooner or have inconsistent binding issues. This Glock G17 Magazine Spring, Not G43 truly restores the magazine to its factory-fresh operational standard.

Breaking Down the Features of Glock G17 Magazine Spring, Not G43

Specifications

The core specification of the Glock G17 Magazine Spring, Not G43 is its material and design, engineered by Glock for their popular G17 pistols. It’s a high-tensile steel coil, specifically calibrated to provide the correct amount of force to reliably feed 9mm ammunition from a standard capacity Glock 17 magazine. While exact spring rate figures are proprietary, its performance indicates a precise engineering for consistent pressure.

This calibrated force is critical; too weak a spring and rounds won’t feed reliably, leading to malfunctions. Too strong a spring and it can increase wear on the follower, feed lips, and even make magazine loading more difficult. The Glock engineers have found a sweet spot here that balances reliable feeding with manageable tension.

Performance & Functionality

The primary function of this magazine spring is to ensure consistent and reliable feeding of ammunition into the firearm’s chamber. The Glock G17 Magazine Spring, Not G43 excels at this. It provides the necessary upward pressure on the magazine follower, pushing each round into position for the slide to chamber it.

Its greatest strength is its uncompromising reliability. It performs its singular task without fuss or failure. I haven’t encountered any feeding issues since installing it. Its main weakness, if one could even call it that, is its singular focus; it doesn’t have any “extra” features beyond optimal performance for its intended purpose.

It not only meets but exceeds the expectations for a replacement part of this nature, especially when compared to the performance degradation of an older spring. Considering its very reasonable price point, its contribution to the firearm’s overall reliability is immense.

Design & Ergonomics

From a design standpoint, this is a simple, functional component. It’s a precisely wound coil of high-tensile steel. The finish is typically a dark, corrosion-resistant coating.

Ergonomics aren’t applicable to a magazine spring in the way they are to a firearm’s grip, but its design contributes directly to the ergonomics of magazine use. A properly functioning spring makes loading and unloading smoother, and critically, ensures that the firearm cycles smoothly, which is paramount for the shooter’s confidence and control. The markings on the product packaging (SP33510) are clear and confirm its OEM status.

Durability & Maintenance

As a replacement spring for a Glock 17 magazine, this part is designed for longevity under repeated stress. Glock components are renowned for their durability, and this spring is no exception. While designed to be a replacement part, it’s built to last through thousands of cycles.

Maintenance is virtually non-existent beyond keeping the magazine clean. Unlike some other firearm components, there’s no adjustment or intricate cleaning required. The spring’s design inherently resists dirt ingress.

The potential failure point for any magazine spring is fatigue over an extended period of use. However, given the quality of Glock manufacturing and the typical use case, this spring should provide reliable service for many thousands of rounds.

Accessories and Customization Options

This is a singular component, a Glock OEM Magazine Spring, and as such, it does not come with accessories, nor does it have customization options in itself. Its purpose is to be a direct replacement for the original spring within a Glock 17 magazine. It is designed to work exclusively within Glock magazines for the G17 model and is not intended for use in other firearm platforms or magazine types.

Pros and Cons of Glock G17 Magazine Spring, Not G43

Who Should Buy Glock G17 Magazine Spring, Not G43?

This Glock G17 Magazine Spring, Not G43 is an essential purchase for any Glock 17 owner who performs regular maintenance on their firearms or participates in competitive shooting, tactical training, or simply wants to ensure their firearm is always ready.

It’s also a smart item to keep in your range bag as a spare.

Those who should probably skip this part are owners of Glock models other than the G17 (as it is not G43 compatible, despite the name indicating a distinction), or individuals who have already replaced their springs recently and are experiencing no issues. I would recommend also purchasing a basic magazine disassembly tool if you don’t already have one, as it makes the process cleaner and protects the magazine’s feed lips.

The value proposition here is outstanding. For less than the cost of a single magazine, you can revitalize multiple older magazines, extending their service life and maintaining peak performance. I would wholeheartedly recommend this component to any Glock 17 owner. If your magazines are showing their age, or if you simply want to maintain your firearm at its best, this is a non-negotiable replacement part that guarantees dependable performance.
