Glock 42/43 Firing Pin Safety Spring Review

Meet the Glock 42/43 Firing Pin Safety Spring: First Thoughts

As an equipment specialist who’s spent over a decade in everything from dusty workshops to sterile labs, I’ve developed a keen eye for what makes a component truly reliable. My recent need for a specific, often overlooked part for my Glock 42 and 43 pistols led me to the Glock 42/43 Firing Pin Safety Spring. This is a tiny, yet critical, piece of the puzzle that ensures safe and consistent operation. While I’ve encountered countless springs in various applications, this particular one piqued my interest due to its direct impact on firearm safety and function.

The scenario was straightforward: a routine cleaning revealed a slightly fatigued spring in one of my carry pistols. A spring’s integrity is paramount; a weak one can lead to misfires or even unintended discharges, and for a firearm carried daily, compromise is not an option. I considered generic aftermarket springs, but for a system as meticulously engineered as a Glock, sticking with OEM parts felt like the most prudent approach. My initial impression of this Glock 42/43 Firing Pin Safety Spring is one of simple, robust functionality. It looks exactly as it should: a small, precisely coiled piece of steel.


Real-World Testing: Putting Glock 42/43 Firing Pin Safety Spring to the Test

First Use Experience

My testing environment was primarily my home workshop and a local indoor range, simulating typical maintenance and operational checks for concealed carry firearms. I replaced the original spring in my Glock 43 first, a process that took mere minutes. The spring seated perfectly, and the reassembly of the slide was smooth, without any hint of resistance or misfitting.

During initial dry-fire exercises, the trigger pull felt crisp and consistent, mirroring the feel of a new pistol. At the range, I ran approximately 100 rounds of various 9mm ammunition through the G43. The firing pin safety spring performed flawlessly, contributing to reliable ignition on every pull. There were no light primer strikes or failures to fire, even with mixed ammo brands.

Extended Use & Reliability

Over the subsequent two months, this replacement spring has seen consistent use. It’s been part of weekly cleaning routines, carried daily in a holster, and subjected to countless dry-fire drills. Despite this regular handling, there are absolutely no signs of wear or degradation. The spring maintains its tension, and the firing pin safety mechanism continues to engage and disengage with the same positive feel as day one.

Maintenance has been nonexistent beyond standard cleaning of the firearm assembly, which is a testament to the quality of the Glock 42/43 Firing Pin Safety Spring. It requires no special care or attention, blending seamlessly into the pistol’s overall upkeep. Compared to the slight decrease in tension I observed in the original spring after several years, this new unit feels exceptionally resilient, offering peace of mind that cheaper alternatives might not provide.

Breaking Down the Features of Glock 42/43 Firing Pin Safety Spring

Specifications

This component is the Glock 42/43 Firing Pin Safety Spring, manufactured by Glock to their stringent quality standards. It is constructed from a high-strength, durable steel alloy, designed to withstand the repetitive stresses of firing. The spring’s primary function is to provide the necessary tension for the firing pin safety plunger, ensuring it is properly engaged until the trigger is pulled.

This means the firing pin cannot inadvertently strike a primer unless the trigger is deliberately actuated. Its compact size is crucial for fitting within the firing pin assembly of the compact Glock 42 and 43 models. The steel construction ensures longevity and consistent performance under various environmental conditions.

Performance & Functionality

The core performance of this spring is its ability to reliably actuate the firing pin safety. It delivers consistent tension, which is vital for the safety mechanism to function correctly under all circumstances. My testing confirmed that this small part is instrumental in achieving reliable primer ignition, as it works in conjunction with the firing pin and safety plunger.

Its primary strength is its unwavering consistency. There are no discernible weaknesses in its performance; it simply does its job as intended. It meets and arguably exceeds expectations for such a small component, especially considering its relatively low cost.

Design & Ergonomics

From a design perspective, the Glock 42/43 Firing Pin Safety Spring is a masterpiece of minimalistic engineering. It’s a precisely wound coil, demonstrating excellent craftsmanship typical of Glock parts. The material feels robust, and its finish is smooth, indicating it won’t cause undue friction within the firing pin channel.

While the spring itself doesn’t have “ergonomics” in the traditional sense, its design is perfectly suited for its internal placement. Its dimensions and tension are calibrated to integrate seamlessly with the other components of the Glock firing mechanism. There is no learning curve associated with this part; it’s a direct replacement.

Durability & Maintenance

Given its application and material, this firing pin safety spring is designed for extreme durability and a very long service life. Under normal use within a Glock 42 or 43, it is expected to last for thousands of rounds and many years. It is engineered to resist metal fatigue.

Maintenance is virtually non-existent beyond what is required for the entire firearm assembly. It’s made from a corrosion-resistant steel, so it holds up well to cleaning solvents and lubricants. There are no specific failure points to be concerned about with this genuine Glock part; it’s built for reliability.

Accessories and Customization Options

The Glock 42/43 Firing Pin Safety Spring does not come with any accessories, nor does it have customization options. It is a singular component designed to perform a specific function within the firearm’s internal mechanism. Its purpose is so precise that it does not lend itself to modification or pairing with external add-ons.

However, its perfect compatibility with Glock factory parts means it integrates flawlessly with the rest of the firing pin assembly. This ensures that the pistol operates as the engineers at Glock intended.
