One Month Later: Apex Tactical Specialties Flat Forward Set Trigger Kit for Sig P320 Review
As a gear and equipment specialist with over a decade of putting tools through their paces in demanding environments, I’m always on the lookout for upgrades that genuinely enhance performance. The Apex Tactical Specialties Flat Forward Set Trigger Kit for Sig P320 caught my eye as a promising contender for improving one of the most critical aspects of any firearm – the trigger. This kit replaces the factory trigger bar and curved trigger with precision-machined components designed to reduce travel and reset, while the flat trigger face aims to improve ergonomics and perceived pull weight.
My journey to this Apex kit began with my Sig P320. While a reliable and capable platform, the stock trigger, like many factory-issued triggers, left something to be desired in terms of crispness and a distinct reset point. I found myself wanting a more refined feel that would translate to quicker follow-up shots and improved accuracy, especially during dynamic shooting exercises. After experiencing a bit of sponginess and excessive take-up in the stock trigger, I knew an aftermarket upgrade was in order.
The initial impression upon unboxing was one of solid craftsmanship. The machined steel components felt substantial, and the flat trigger face had a clean, aggressive look that hinted at its performance intentions. I had considered other trigger upgrades, including those that involved significant stippling or custom grip modifications, but Apex’s direct-replacement approach appealed to my desire for a straightforward, yet effective, enhancement. My first reaction was one of optimistic anticipation, eager to see if this kit could deliver on its ambitious promises.
Real-World Testing: Putting Apex Tactical Specialties Flat Forward Set Trigger Kit for Sig P320 to the Test
First Use Experience
My testing grounds for this trigger kit were primarily at my local indoor shooting range, interspersed with dry-fire practice at home. The installation process itself was surprisingly straightforward, taking less than 10 minutes with zero issues, mirroring the “direct drop-in” claim. The kit came with the necessary components, and Apex provides a helpful installation video.
The most immediate difference was felt during dry-fire. The take-up was dramatically reduced, feeling almost nonexistent before the wall. The reset was incredibly short and distinct, a welcome departure from the mushy feel of the stock trigger. At the range, this translated into faster and more confident shooting. The reduced trigger travel meant less time spent at the wall, and the crisp reset allowed for quicker, more precise follow-up shots.
One minor quirk I noticed initially was a slight adjustment period to the flat trigger face. While it increased leverage, as advertised, it took a few magazines to fully adapt my finger placement for optimal comfort and control. This is less a flaw of the kit and more a personal adaptation to a different trigger geometry.
Extended Use & Reliability
After putting approximately 500 rounds through my P320 with the Apex kit installed, the reliability has been 100%. There have been no malfunctions or performance drops whatsoever. The trigger continues to feel as crisp and responsive as it did on day one.
Durability appears to be excellent. The machined steel components show no signs of wear, scratches, or any other damage, even after being handled frequently and subjected to the rigors of range bags. Maintenance is minimal; a simple field strip and cleaning of the pistol includes the trigger components as well, requiring no special attention beyond what’s needed for the firearm itself.
Comparing it to my previous experience with a stock P320 trigger, this Apex kit is a significant upgrade. It offers a more refined and responsive shooting experience that elevates the overall feel of the pistol. While I haven’t directly compared it side-by-side with other premium aftermarket triggers like those from Gray Guns, the performance and quality of the Apex kit make it a compelling option that justifies its price point.
Breaking Down the Features of Apex Tactical Specialties Flat Forward Set Trigger Kit for Sig P320
Specifications
The Apex Tactical Specialties Flat Forward Set Trigger Kit for Sig P320 is a meticulously engineered upgrade designed for specific Sig Sauer P320 models. It consists of three core components: the Flat Advanced Trigger, the Forward Set Trigger Bar, and an Over-Travel Stop with its accompanying spring. These parts are precision-machined from billet steel, ensuring durability and consistent performance.
The primary function of the Forward Set Trigger Bar is to alter the geometry of the trigger mechanism, thereby reducing both trigger travel and reset distance. Apex claims this reduction to be approximately 30% for overall travel and 20% for reset. The Flat Advanced Trigger itself is designed to increase trigger reach and leverage by allowing the shooter to position their finger lower on the trigger face. This change in angle, along with the improved internal mechanics, aims to create a perceived lighter trigger pull and a crisper break.
It’s crucial to note that this kit is ONLY for use in “factory upgraded” P320 models that feature the full complement of safety enhancements. It is not compatible with non-factory upgraded P320s, Thumb Safety models, or the Sig Sauer P250. The kit is also not recommended for use in the Sub-Compact Grip Module due to internal dimension variations.
Performance & Functionality
The main job of this trigger kit is to improve the shooting experience of the Sig P320, and it excels at this. The reduction in trigger travel is palpable; the slack is virtually eliminated, and you reach the wall of the trigger pull much sooner. This makes it easier to maintain a consistent sight picture as you prepare to fire.
The reset is where this kit truly shines. It’s incredibly short and tactile, allowing for rapid and accurate follow-up shots. You can feel and hear the distinct click of the trigger resetting, enabling a proactive pull for the next shot rather than a hesitant reaction.
The expected results of approximately 30% reduction in trigger travel and 20% reduction in reset seem to be accurate based on my real-world testing. The trigger pull weight reduction is where it gets a bit nuanced. While Apex advertises an approximate 30% reduction in trigger pull weight, some user feedback suggests this is more about the perceived weight due to the flat face and altered leverage. On X-Series models, the pull weight reduction is explicitly stated as not occurring, but overall travel is still reduced by 30%. My own experience aligns with a crisper, more defined break rather than a drastically lighter pull, though the improved leverage does make it feel lighter and easier to manage. Crucially, the kit maintains factory drop safety values, which is paramount.
Design & Ergonomics
The Tactical Flat trigger shape is a significant ergonomic improvement over the stock curved trigger. It provides a larger, more consistent surface area for your finger, and as mentioned, allows for a lower, more advantageous finger placement. This increased leverage can contribute to a feeling of greater control and precision.
The machined billet steel construction speaks to a high level of build quality. The finish is a uniform Black, and the overall feel of the components is robust and durable. There are no sharp edges or rough spots, indicating good manufacturing tolerances.
The design is focused on function, and it delivers. The flat face, combined with the reduced take-up and short reset, creates a trigger experience that feels more competition-oriented or precision-focused, even on a standard P320. The ease of installation, requiring no special tools or fixtures, is another testament to the thoughtful design.
Durability & Maintenance
Based on my experience and the material used (billet steel), the Apex Tactical Specialties Flat Forward Set Trigger Kit for Sig P320 is built for the long haul. The kit is designed as a permanent upgrade, and there’s no indication that these components will wear out prematurely under typical use for a firearm of this type.
Maintenance is straightforward. The kit integrates into the P320’s existing mechanism, so care involves standard firearm cleaning and lubrication procedures. The Over-Travel Stop component is particularly useful for preventing excessive rearward movement of the trigger after the break, which can aid in both accuracy and preventing accidental double-taps. Ensuring this small component and its spring are properly seated during installation and reassembly is key.
There aren’t really any specific maintenance tips beyond general firearm care. However, a user in the feedback mentioned bending the trigger return spring during disassembly. It’s wise to be cautious with small springs during any firearm disassembly, and watching Apex’s provided installation video can help avoid such minor mishaps.
Accessories and Customization Options
This trigger kit comes with the essential components needed for the upgrade:
- 1 ea. Flat Advanced Trigger: The primary interface for the shooter.
- 1 ea. Forward Set Trigger Bar: The crucial component for reducing travel and reset.
