How the Apex Tactical Specialties Action Enhancement Kit for the FN 509 Surprised Me
As an equipment specialist with over a decade of experience across diverse environments, I’ve developed a keen eye for what truly enhances performance and reliability. My FN 509 has always been a capable platform, but I felt it lacked a certain refinement in its trigger, a common sentiment among many owners. I sought an upgrade that would offer a more precise and crisp shooting experience without compromising safety or functionality. My search led me to the Apex Tactical Specialties Action Enhancement Kit for the FN 509, a direct replacement kit promising significant improvements. The initial impression upon receiving the kit was one of professional packaging and clearly marked components, hinting at the quality within. While I considered simply living with the stock trigger, the prospect of a demonstrably better shooting dynamic was too enticing. My first reaction was one of hopeful anticipation, a feeling that this upgrade might finally unlock the full potential of my pistol.
Real-World Testing: Putting the Apex Tactical Specialties Action Enhancement Kit for the FN 509 to the Test
First Use Experience
My testing primarily took place at my local indoor shooting range, a controlled environment that allows for consistent evaluation of trigger feel and performance. I also conducted dry-fire practice at home to meticulously analyze the pre-travel, wall, and reset. The installation itself was straightforward, following Apex’s clear video tutorials, though having the right set of tools certainly eased the process. For initial use, I focused on slow, deliberate shots to feel the distinct changes, then transitioned to rapid fire to assess consistency and reset.
One of the initial surprises was how much smoother the entire action felt, even before the first live fire. The take-up was more consistent, and the break, while still requiring a firm press, was remarkably cleaner. I experienced no malfunctions or unexpected behavior during these initial sessions.
Extended Use & Reliability
After several hundred rounds through the pistol with the Apex kit installed, its performance has remained exceptionally consistent. The enhanced trigger has become second nature, and I no longer find myself anticipating any “mushiness” or uncertainty in the break. There are no visible signs of wear and tear on the trigger components, which speak volumes about the quality of the materials Apex Tactical uses.
Maintenance has been as simple as regular field stripping and cleaning of the firearm itself; the kit components do not require special attention beyond standard care. Comparing this to my previous experience with just swapping out a trigger shoe, the full kit offers a more holistic improvement. The Apex kit’s reliability has surpassed my expectations, maintaining its crisp break and reduced pull weight without any degradation.
Breaking Down the Features of the Apex Tactical Specialties Action Enhancement Kit for the FN 509
Specifications
The Apex Tactical Specialties Action Enhancement Kit for the FN 509 is designed as a direct drop-in replacement for the factory polymer trigger, trigger bar, and sear. Its core promise is to reduce the trigger pull weight to approximately 5.5 lbs, a significant improvement over stock. Furthermore, it aims to reduce pre-travel, over-travel, and overall trigger travel, while also shortening the trigger reset distance. The kit includes an Apex Flat-Faced Action Enhancement Trigger with an integrated Apex Trigger Bar, and an Apex Performance Sear.
These specifications translate directly into a more responsive and controllable shooting experience. A lighter, crisper pull means less disturbance of the firearm during the critical moment of discharge, leading to better accuracy. The reduced travel and shorter reset allow for faster follow-up shots. This focus on all aspects of trigger function, from initial movement to the break and reset, is what sets this kit apart.
Performance & Functionality
The primary function of this kit is to dramatically improve the FN 509’s trigger. It succeeds exceptionally well in this regard. The pull is significantly smoother than the factory offering, with a more defined wall and a clean, decisive break. The reduced reset distance is a standout feature, allowing for quick and efficient follow-up shots without the need for excessive trigger “slap” or over-travel to feel the reset.
The main strength lies in the holistic nature of the upgrade; it’s not just a lighter pull, but a complete re-engineering of the trigger system’s feel and function. Its primary weakness, if one can even call it that, is that it makes the stock trigger feel even more inadequate by comparison. It absolutely meets and exceeds expectations for a performance enhancement in this price range.
Design & Ergonomics
The Apex Flat-Faced Action Enhancement Trigger offers a superior feel compared to the factory curved trigger. Its flat face provides a consistent surface for finger placement, promoting a straighter pull. The materials used feel robust and well-machined, contributing to a perception of high quality.
Ergonomically, the trigger is comfortable and the reduced travel makes it easier to manage during rapid fire. The center-mounted pivoting safety maintains factory safety values, which is crucial for any firearm modification. There’s virtually no learning curve for the trigger’s operation itself; it feels natural, albeit significantly improved. The sturdy construction inspires confidence.
Durability & Maintenance
Based on my extended use and the reputation of Apex Tactical, I anticipate excellent long-term durability from this kit. The components are engineered for consistent performance under stress. The materials appear to be high-grade steel and robust polymers, designed to withstand repeated use without issue.
Maintenance is straightforward. Standard firearm cleaning procedures are sufficient, ensuring the trigger mechanism remains free of debris. There are no special lubrication requirements or parts that are prone to premature wear. Potential failure points are minimized by the inherent quality of the engineering.
Accessories and Customization Options
The Apex Tactical Specialties Action Enhancement Kit for the FN 509 is a self-contained upgrade. It includes the flat-faced trigger with trigger bar, and the performance sear. There are no additional accessories in the package, nor are there any inherent customization options for the kit components themselves beyond the flat face of the trigger.
However, it is designed to be compatible with the FN 509 platform itself, meaning it integrates seamlessly with the existing firearm’s safety mechanisms and other factory parts that are not replaced by the kit. The focus is on a refined, optimized trigger system rather than modularity.
