Glock 42/43 Firing Pin Safety Spring Review

Let’s Talk About Glock 42/43 Firing Pin Safety Spring

The Glock 42/43 Firing Pin Safety Spring, a seemingly insignificant part, is absolutely crucial to the safe and reliable operation of these popular concealed carry pistols. The Glock pistol family, renowned for its simplicity and dependability, relies on this small spring to prevent accidental discharge, ensuring the firing pin only moves when the trigger is intentionally pulled. It is a critical component in the overall safety mechanism.

As a firearms enthusiast and someone who prioritizes safety above all else, I was compelled to examine the Glock 42/43 Firing Pin Safety Spring due to reports of failures in older or high-round-count pistols. I wanted to understand its role, its potential for wear, and the importance of replacing it when necessary. This led me on a journey of research and hands-on exploration with this vital component.

Upon receiving the Glock 42/43 Firing Pin Safety Spring, my initial impression was that it’s, well, just a spring. It’s small and unassuming, but a closer look revealed a precisely engineered piece of coiled steel. Its build quality appeared to be consistent with Glock’s reputation for reliable parts.

While it’s difficult to directly compare a spring to other products in the same way you would compare firearms, I’ve certainly used aftermarket firing pin safety springs in the past. Some promise lighter trigger pulls, but I’ve always been wary of compromising safety for performance. The Glock factory spring is what I trust.

My first impression was cautiously optimistic. While visually simple, the Glock 42/43 Firing Pin Safety Spring’s importance to the overall reliability and safety of the firearm is undeniable. Knowing Glock’s reputation, I expected a durable and reliable component, but the real test would come in understanding its behavior during firing.

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

First Use Experience

I installed the new Glock 42/43 Firing Pin Safety Spring in my Glock 43 at the range, after a thorough cleaning of the slide assembly. I immediately noticed a smoother feel during dry-firing, a subtle but perceptible change. The spring’s primary function isn’t directly felt, but its correct operation ensures the firing pin block functions as designed, preventing accidental discharge.

I tested the pistol through several magazines under varied conditions. The range was dry and moderately warm, a fairly standard testing environment. The functionality of the firing pin safety was verified by repeatedly attempting to induce an accidental discharge through dropping the slide from slide-lock, which is of course standard safety practice with all pistols.

The installation process, though straightforward for anyone familiar with Glock disassembly, highlighted the need for proper tools. I didn’t encounter any immediate issues. It was a positive indication that the Glock 42/43 Firing Pin Safety Spring was functioning as expected, contributing to the pistol’s safe operation.

Extended Use & Reliability

After several hundred rounds fired over the course of a few months, the Glock 42/43 Firing Pin Safety Spring continues to perform flawlessly. I’ve noticed no degradation in trigger feel or any indication of malfunctions. The spring remains consistent and reliable.

Inspecting the slide assembly during routine cleaning reveals no signs of unusual wear or deformation of the spring itself. This is critical. A properly functioning firing pin safety spring is crucial for preventing accidental discharges.

Maintenance is minimal; regular cleaning of the slide assembly is all that’s required to keep the spring functioning optimally. My experience with the Glock 42/43 Firing Pin Safety Spring has reinforced my trust in Glock factory parts. Its performance and reliability have exceeded my expectations.
