About this product

Action Enhancement Kit for FNS by Apex Tactical. Fits Apex Tactical.

Available for delivery across the United States.

The Action Enhancement Kit for the FNS is built for shooters who demand reliability in Arizona’s extreme conditions. Whether you’re on a dusty range near Tucson or running drills under the desert sun, this drop-in kit keeps your trigger performing through high heat, fine grit, and suppressor use. Here’s what it does for your FNS:

• Reduced trigger pull to approximately 5.5 lbs. – Lighter, consistent pull weight helps you stay on target without fighting a heavy factory trigger. Perfect for high-volume range days or competition.
• Shorter pre-travel, over-travel, and reset distance – Less wasted movement means faster follow-up shots. You’ll feel the difference when shooting from a holster or transitioning between targets.
• Crisp, defined break – No mush or creep. The break is clean and predictable, which matters when dust and heat can already challenge your grip and sight picture.
• Maintains factory safety values with a center-mounted pivoting safety – Your firearm stays drop-safe and reliable. No compromise on safety, even with a lighter pull.
• Direct drop-in replacement – no fitting required – Install it yourself in minutes. No filing, polishing, or gunsmithing. Just swap the original parts and your FNS is ready to run.

Specs and fitment: The kit is designed specifically for the FNS series (FNS-9, FNS-40, FNS-9C, FNS-40C). It uses a patent-pending design that originated as the first drop-in trigger kit for this platform. The center-mounted pivoting safety maintains the factory sear engagement angles, so you get a lighter pull without altering the internal geometry. This makes it suitable for suppressor use—the reduced reset and consistent break help you manage recoil and stay on target during suppressed fire, where gas blowback and heat can affect trigger feel. In high-dust environments, the drop-in design keeps the trigger pack sealed and protected from debris. The reduced pull weight also helps compensate for the added friction and drag that dust and heat can introduce to other trigger components. Price: $160. Category: FN, Triggers, Trigger Kits. For Tucson Arms customers, this kit delivers a measurable upgrade for your FNS without the hassle of custom work. It’s a practical, field-proven solution for shooters who need their pistol to perform in the toughest conditions.
