One Tool, Many Questions: The LANTAC S-KIT Upgrade Glock 17/19 Gen1-4 Spring Kit
As an enthusiast who has spent over a decade putting gear through its paces in everything from dusty workshops to sterile labs and challenging field conditions, I’ve learned that even the smallest components can make a significant difference. This is precisely why I found myself looking at the LANTAC S-KIT Upgrade Glock 17/19 Gen1-4 Spring Kit. My Glock 19, a trusted companion for various applications, had been feeling a bit less refined lately, with a trigger pull that, while functional, lacked the crispness I’d grown accustomed to. I wasn’t looking for a complete overhaul, just a subtle enhancement to improve its overall feel and performance. This LANTAC kit, promising reduced friction and a smoother pull, seemed like a straightforward solution. I briefly considered generic spring sets from online marketplaces, but LANTAC’s reputation for precision engineering across various firearm platforms ultimately steered me towards this specific upgrade. My initial impression upon receiving the kit was one of quiet satisfaction; the packaging was minimal yet secure, and the springs themselves looked meticulously crafted, hinting at the quality I expected.
Real-World Testing: Putting LANTAC S-KIT Upgrade Glock 17/19 Gen1-4 Spring Kit to the Test
First Use Experience
My initial testing environment was my home workshop, a controlled space where I could meticulously install and test the springs without external distractions. The installation was remarkably straightforward, taking less than ten minutes, fitting perfectly into my routine of routine firearm maintenance. I performed the installation on a clean workbench, ensuring no dust or debris could interfere with the delicate parts.
The performance improvement was immediately noticeable. The trigger pull felt significantly smoother, with a discernible reduction in the gritty sensation I’d experienced previously. This upgrade truly shone during my subsequent range days.
Extended Use & Reliability
After several months of regular use, including multiple range sessions and even a few days out on a property where dust and light moisture were present, the LANTAC springs have held up exceptionally well. There are absolutely no signs of wear and tear, such as cracks or stiffness, which is a testament to the quality of the materials.
Cleaning and maintenance remain as simple as they were before the upgrade, requiring only standard firearm cleaning protocols. Compared to budget spring kits I might have tried in the past, these LANTAC springs have maintained their consistent performance without any degradation. This is a crucial factor when reliability is paramount, and these springs deliver.
Breaking Down the Features of LANTAC S-KIT Upgrade Glock 17/19 Gen1-4 Spring Kit
Specifications
The LANTAC S-KIT Upgrade Glock 17/19 Gen1-4 Spring Kit is designed to enhance Glock models 17 and 19, specifically generations one through four. It includes a set of precisely engineered springs that aim to improve trigger pull characteristics. The key components are the firing pin springs and a trigger spring, all calibrated for consistent force delivery.
Each spring in the kit is tempered to ensure it maintains its specified tension throughout its operational lifespan. This means you can expect reliable performance over hundreds, if not thousands, of trigger pulls.
The kit offers four different spring strengths for the firing pin, catering to various needs: a 4.0lb Firing Pin Spring for target and competition use, a 4.5lb Firing Pin Spring, a 6.0lb Firing Pin Spring for carry and self-defense, and a 6.5lb Firing Pin Spring for maximum reliability. Crucially, it also includes two trigger springs: one 6.0lb Increased Power Trigger Spring and one Reduced Power Firing Pin Safety Spring. This variety allows for significant customization of the trigger feel.
The reduced power trigger spring contributes to a lighter, crisper pull, reducing the effort needed to actuate the trigger. Conversely, the increased power trigger spring offers a bit more resistance, which some users may prefer for deliberate control.
Performance & Functionality
The primary job of this spring kit is to refine the trigger pull, and it excels at this. The reduction in friction between the firing pin plunger and the trigger bar results in a noticeably smoother action. This translates to improved accuracy potential as the shooter is less likely to disturb the sight picture during the trigger press.
One of the standout benefits is the significant reduction in trigger pull weight. Depending on the specific spring combination used, users can expect as much as a 1-pound reduction in overall trigger pull weight. This makes a substantial difference in how controllable and enjoyable the firearm feels to shoot.
The enhanced reliability aspect, particularly with the higher poundage firing pin springs, is also a major plus. For defensive use, ensuring positive ignition every time is critical, and these springs contribute to that confidence.
Design & Ergonomics
While springs are internal components and not directly felt ergonomically, their design directly impacts the feel of the external controls. The precision manufacturing of these LANTAC springs ensures they seat correctly and function without binding. The materials used are high-grade steel, chosen for their resilience and consistent spring rate.
The careful calibration of each spring is a design feature that prevents common issues like light primer strikes or unintended trigger reset problems. This thoughtful engineering means that even though you don’t see them, you absolutely feel the quality of the design through the improved operation of your firearm.
Durability & Maintenance
Given the materials and LANTAC’s manufacturing standards, these springs are built for longevity. Under normal use, particularly in a handgun that isn’t subjected to extreme environmental conditions or constant rapid firing without breaks, they should last for many thousands of cycles.
Maintenance is virtually non-existent in terms of the springs themselves; they require no special cleaning or lubrication beyond standard firearm care. The main concern would be during installation or disassembly, ensuring no other parts are damaged.
Accessories and Customization Options
This kit provides the springs themselves, and crucially, the choice of which springs to use. The variety of firing pin spring weights is a significant customization feature, allowing users to tune their Glock to their specific needs—be it for competitive shooting, concealed carry, or general recreational use.
The inclusion of both a higher and a standard trigger spring offers further customization for those who might have differing preferences for trigger feel. This level of adaptability within a single kit is excellent.
