Glock G22 & G37 11 Coil Mag Spring Review

What Makes the Glock G22 & G37 11 Coil Mag Spring Click?

As an equipment specialist with over a decade navigating the demands of varied environments, from dusty workshops to sterile labs and rugged fields, I’ve learned that the devil is often in the details. This rings especially true for firearms maintenance, where a seemingly minor component can dictate overall reliability. It was a subtle but persistent feeding issue with my Glock G22 that led me down the path of exploring a replacement for its internal magazine spring. I needed a part that could restore that original crisp feeding action without compromise.

The Glock G22 & G37 11 Coil Mag Spring presented itself as a direct OEM solution, promising to bring my firearm back to its intended performance. My initial impression upon receiving the single, coiled wire was one of solid, unadorned functionality. It felt robust, possessing that characteristic Glock no-nonsense utilitarianism even in its simplest form. I briefly considered generic aftermarket springs, but the allure of guaranteed Glock OEM quality and the minimal price difference quickly steered me back to this specific part.

The immediate feeling was one of quiet confidence; a subtle relief that a simple, affordable fix might be at hand. This wasn’t about groundbreaking technology, but about restoring a fundamental function to a trusted tool.

Real-World Testing: Putting Glock G22 & G37 11 Coil Mag Spring to the Test

First Use Experience

My testing ground for this particular component was straightforward: my personal Glock G22, specifically its factory 15-round magazines. The initial installation took place on my workbench, under good lighting. It was a simple matter of disassembling the magazine and swapping out the old spring for the new Glock G22 & G37 11 Coil Mag Spring.

The first real test came during a routine range session. I loaded the magazine, ensuring each round seated properly against the new spring’s tension. I then proceeded with a series of drills, focusing on rapid firing and deliberate slow fire to observe feeding consistency. The spring performed admirably, offering no hiccups or feeding failures across a few hundred rounds.

After this initial range trip, I noticed a definite improvement in the smoothness of magazine loading and, more importantly, consistent feeding. There was no discernible difference in performance with light moisture from a humid range day, nor did dust from the range environment seem to affect its function. The ease of use was paramount; it was designed to fit and function, and it did so intuitively.

Extended Use & Reliability

Following that initial successful outing, the Glock G22 & G37 11 Coil Mag Spring has remained in constant service in my Glock G22 magazines. Over several months, these magazines have been loaded and unloaded countless times, subjected to varying temperatures, and have experienced the usual bumps and jostles that come with regular handling.

Durability has been excellent. There are no visible signs of fatigue, kinks, or loss of tension in the spring. It maintains its firm, consistent pressure on the magazine follower, ensuring reliable feeding round after round. I’ve encountered no premature wear, unlike some cheaper, unbranded springs I’ve used in other applications that can develop a “set” over time.

Maintenance for a magazine spring is inherently minimal. Cleaning involves the typical magazine disassembly, wiping down the interior and the spring itself, and then reassembly. It’s a quick process that doesn’t require special tools or chemicals. Compared to my previous experience with older, worn-out springs that would occasionally cause feeding failures or require more aggressive magazine cleaning, this OEM part is a dream. It simply works, without demanding constant attention or specialized care.

Breaking Down the Features of Glock G22 & G37 11 Coil Mag Spring

Specifications

The Glock G22 & G37 11 Coil Mag Spring is a precisely engineered component. It is officially listed as an OEM (Original Equipment Manufacturer) part designed specifically for Glock models G22 and G37.

• Manufacturer: Glock
• Gun Model Compatibility: Glock 22, Glock 37
• Coil Count: 11 coils
• Part Number: SP33601

This specification of 11 coils is crucial. It dictates the amount of spring tension applied to the magazine follower. This tension is what reliably pushes each round up towards the chamber for consistent feeding. The Glock manufacturer designation ensures it meets the rigorous quality control and design standards set by the firearm’s original maker. Its compatibility with both the G22 and G37 models speaks to a shared magazine design philosophy between these particular Glock firearms.

Performance & Functionality

The primary job of this magazine spring is to ensure reliable feeding of ammunition. It excels at this core function. The 11 coils provide consistent, strong pressure that effectively bridges the gap between a fully loaded magazine and the last round.

• Feeding Reliability: This is where the spring truly shines. It guarantees that rounds are presented to the slide chamber smoothly and without failure, even under rapid fire conditions.
• Magazine Loading: The spring’s tension also plays a role in the feel of loading a magazine; it offers firm resistance, which is expected from a new, properly tensioned spring.
• Durability: As mentioned, its real-world performance suggests excellent longevity. It’s built to withstand the repeated compression and expansion cycles inherent to magazine use.

It meets and exceeds expectations for its intended purpose. The price point of $5.88 is exceptionally reasonable for an OEM part that directly impacts firearm reliability.

Design & Ergonomics

As a coiled spring, the design is inherently simple: a length of high-tensile steel wire wound into a specific configuration. Its “ergonomics” are less about how it feels in the hand and more about how it interfaces within the magazine.

The perceived sturdiness is high. It’s a compact piece of metal, but its resilience is evident even before installation. There are no complex mechanisms or delicate points; it’s pure mechanical function.

The design is entirely focused on its utilitarian purpose. The 11-coil configuration is the critical ergonomic feature, ensuring it fits perfectly within the magazine tube and interacts correctly with the follower.

Durability & Maintenance

For a component like this, “durability” is measured in its ability to maintain its spring tension and structural integrity over time and use. Based on my experience, this Glock OEM spring is built for the long haul.

It’s likely designed to outlast the average user’s need for replacement, barring extreme misuse or exposure to corrosive elements. Maintenance is straightforward, primarily involving cleaning the magazine body and the spring itself during routine firearm upkeep. I have encountered no specific failure points with this type of OEM spring.

Accessories and Customization Options

This is a replacement part, not a system requiring accessories. It is designed to be a direct swap for the existing spring within Glock magazines for the G22 and G37.

There are no inherent customization options for the spring itself. Its purpose is singular: to provide reliable feeding. Any “customization” would involve selecting the correct model for your firearm.
