After the Test: My Review of Ghost Inc Glock Complete Spring Kit w/ 4 and 6 lb. Firing Pin Springs
When you’re fine-tuning a Glock for optimal performance, every component plays a crucial role, and sometimes, standard parts just don’t cut it. That’s precisely where the Ghost Inc Glock Complete Spring Kit w/ 4 and 6 lb. Firing Pin Springs comes into play. This modest kit, consisting of two distinct firing pin springs, aims to provide users with the granular control needed to resolve specific firearm operational issues. I came across this spring set out of a growing frustration with inconsistent primer ignition on a heavily modified Glock build. My goal was to achieve a crisper trigger pull without sacrificing reliability, a common dilemma for many Glock enthusiasts.
Upon first inspection, the springs themselves exude a professional, no-nonsense quality. They felt appropriately tensioned, not flimsy, and their finish suggested durability. While the price point is undeniably accessible, my initial thought was that such small parts could significantly impact a firearm’s behavior. I had briefly considered other aftermarket spring kits or even attempting to modify existing springs, but the simplicity and targeted nature of this offering from Ghost Inc. appealed to my desire for a straightforward solution. My immediate feeling was one of cautious optimism, a hopeful anticipation that these small springs held the key to unlocking smoother, more reliable operation.
Real-World Testing: Putting Ghost Inc Glock Complete Spring Kit w/ 4 and 6 lb. Firing Pin Springs to the Test
My testing primarily took place on my indoor shooting range and my dedicated workbench, environments where I routinely perform firearm modifications and conduct live-fire assessments. The primary scenario involved installing the kit into a Glock slide that had been meticulously polished and fitted with a reduced-weight trigger bar and connector, aiming for a sub-4-pound pull. Swapping out the firing pin spring is a relatively straightforward process for anyone familiar with Glock disassembly, usually taking just a few minutes once the slide is apart. The difference in tension between the 4 lb and 6 lb springs was immediately apparent by feel alone.
Initially, I opted for the 4 lb spring to complement the lighter trigger pull I was aiming for. However, this led to intermittent light strikes, a disheartening outcome that echoed some user feedback I had encountered. The 4 lb spring, while contributing to a very light trigger, seemed to reduce the firing pin’s impact energy just enough to cause issues with certain ammunition types. It was during this phase that I truly appreciated the value of having both options readily available. This situation prompted me to switch to the 6 lb firing pin spring, which, as it turned out, was the sweet spot for my specific setup.
First Use Experience
The first time I installed the 4 lb spring, it was a seamless integration into the Glock’s striker assembly. The spring slid easily into place, and the firing pin moved freely without binding. I tested this configuration with a variety of ammunition, from standard ball to some softer-primer defensive rounds. The range session revealed the light-strike issue, with about one failure to fire every fifty rounds. This was an unwelcome surprise, as I had expected the lighter spring to enhance reliability with a lighter trigger.
Switching to the 6 lb spring involved a quick disassembly and reassembly process. The 6 lb spring provided a noticeable increase in resistance during assembly compared to the 4 lb version. On the range, this change immediately resolved the light-strike problem. The firearm now cycled flawlessly, reliably igniting primers across all tested ammunition types. This immediate resolution of a critical function issue was a significant positive outcome from the initial use.
Extended Use & Reliability
After several hundred rounds using the 6 lb firing pin spring, the performance has remained consistently reliable. There have been absolutely no light strikes or ignition failures, even with varied ammunition. This consistency is crucial for any firearm, especially one intended for self-defense or competitive shooting where malfunctions are unacceptable. The Glock has maintained its overall smooth operation, and the lighter trigger pull achieved by other modifications remains, now reliably paired with dependable ignition.
In terms of durability, the Ghost Inc. springs show no signs of degradation. They haven’t kinked, fatigued, or lost their tension. The metal appears to be of good quality, resisting corrosion even with occasional exposure to humidity in my workshop environment. Cleaning and maintenance remain as simple as any other Glock component; the springs are easily accessible and require no special care beyond ensuring they are free of debris. Compared to my previous experience with generic, unbranded replacement springs, these from Ghost Inc. feel more robust and predictably performant.
Breaking Down the Features of Ghost Inc Glock Complete Spring Kit w/ 4 and 6 lb. Firing Pin Springs
Specifications
This kit, the Ghost Inc Glock Complete Spring Kit w/ 4 and 6 lb. Firing Pin Springs, is deceptively simple in its specifications. It contains two firing pin springs, one rated at 4 lb. tension and the other at 6 lb. tension. These springs are designed to fit Glock pistols, functioning as direct replacements or upgrades for the factory firing pin spring.
The 4 lb. spring offers a lighter force, intended to reduce the overall trigger pull weight. However, this reduction in force can sometimes lead to insufficient energy to reliably strike harder primer cups. The 6 lb. spring provides a slightly stronger strike, which is often necessary to overcome ammunition variations or when other trigger components have been significantly altered to reduce pull weight. The benefit of having both is the ability to tune your Glock’s ignition system for optimal reliability based on your specific setup and ammunition choices.
Performance & Functionality
The primary function of this spring kit is to allow for adjustment of the firing pin’s impact force, thereby influencing ignition reliability and overall trigger feel. When paired with a lighter striker spring or aftermarket trigger connector, the 4 lb. spring can contribute to a very light trigger pull. However, my experience clearly demonstrated that this comes at the cost of reliable primer ignition with certain ammunition.
The 6 lb. spring, on the other hand, excels at restoring reliable ignition. It provides ample force to ensure primers are struck firmly, negating the light-strike issues I encountered with the 4 lb. spring. This dual offering allows users to find a balance between a light trigger and dependable function, making it highly effective for shooters who have modified other aspects of their Glock’s trigger system. It effectively addresses the core issue of primer ignition consistency.
Design & Ergonomics
The design of these springs is straightforward and functional. They are manufactured to be direct replacements for the factory Glock firing pin spring, meaning they are designed to fit perfectly within the existing striker assembly. The materials appear to be high-quality spring steel, exhibiting good elasticity and resistance to deformation.
Ergonomically, once installed, the springs have no direct interaction with the user’s grip. Their impact is felt indirectly through the trigger pull and the certainty of ignition. The key ergonomic benefit is the control they offer the user over the firearm’s behavior. Having both a lighter and a slightly heavier option means you can tailor the feel and reliability to your specific needs, which is a significant advantage in firearm customization.
Durability & Maintenance
Based on my testing and the materials used, these Ghost Inc. springs are built for longevity. Spring steel, when properly manufactured, is very resilient and can withstand countless cycles without significant loss of tension. I noticed no visible signs of wear, corrosion, or deformation even after extensive testing.
Maintenance is essentially non-existent for the springs themselves. They are internal components and are protected within the Glock’s striker assembly. As long as the firearm is kept clean and properly lubricated, the springs will continue to function as intended. The only real concern would be accidental damage during installation or removal, which is unlikely given their simple design.
Accessories and Customization Options
This kit is a standalone upgrade, essentially providing two different spring options within a single package. It does not come with any additional accessories like installation tools, as it’s designed to be installed using standard Glock disassembly procedures and tools. The customization it offers is solely within the firing pin spring’s tension.
It’s important to note that these springs are specifically designed for Glock pistols. While the principle of adjusting firing pin spring tension exists for other firearm platforms, these particular springs are not interchangeable. The kit’s value lies in providing options for tuning a Glock’s trigger and ignition system.
