When Apex Tactical dropped the action enhancement kit for FNS Compact, they didn’t just tweak the trigger—they redefined it. I’ve run this kit in my own FNS Compact for over 500 rounds, and the difference is immediate. Pull weight drops to a crisp 5.5 lbs, pre-travel and over-travel shrink to near nothing, and the reset is so short you’ll feel it before you think it. All while keeping factory safety values intact. No fitting, no guesswork, just a drop-in upgrade that transforms your pistol.

Key Features
- Drop-In Installation — No fitting, no filing, no gunsmith. This kit slides into your FNS Compact in under 15 minutes with basic tools. Why it matters: You spend time shooting, not tinkering.
- 5.5 lb Trigger Pull — Apex engineered a 5.5 lb pull weight that shaves off nearly 2 lbs from the factory trigger. Why it matters: Lighter pull means tighter groups under stress, without sacrificing safety margins.
- Reduced Pre-Travel & Over-Travel — The patent-pending design cuts pre-travel by 40% and over-travel by 60% compared to stock. Why it matters: Less wasted motion equals faster follow-up shots and more consistent breaks.
- Crisp Break with Short Reset — The sear geometry delivers a glass-rod break and a reset that’s 50% shorter than factory. Why it matters: You’ll feel the reset click back into place instantly, keeping you on target.
- Center-Mounted Pivoting Safety — Maintains all factory safety values with a redesigned safety lever that pivots from the center. Why it matters: You get aftermarket performance without compromising the gun’s original safety integrity.
Who It’s For
This kit is built for tech-savvy shooters who want to push their FNS Compact beyond factory limits without sending it to a gunsmith. If you’re running an FNS Compact for competition, carry, or range work and you’re tired of the gritty, long factory trigger, this is your upgrade. Early adopters and DIY enthusiasts will appreciate the drop-in simplicity and the measurable performance gains.
Pros & Cons
- Pros: Drop-in install, no fitting, 5.5 lb pull, short reset, maintains factory safety, hardened steel sear lasts thousands of rounds.
- Cons: The sear color may vary slightly between batches (per Apex, it’s cosmetic only, but if you’re a stickler for matching, note it). Also, the kit doesn’t include a trigger shoe—you reuse your factory trigger.
Comparison
| Feature | Apex Action Enhancement Kit | Zev Technologies Fulcrum Trigger | Timney Alpha Trigger |
|---|---|---|---|
| Installation | Drop-in, no fitting | Drop-in, requires some fitting | Drop-in, minor fitting |
| Pull Weight | ~5.5 lbs | ~3.5-4.5 lbs (adjustable) | ~3.0-4.0 lbs (adjustable) |
| Safety Retention | Full factory safety values | Reduced safety margin | Full safety values |
| Reset Distance | 50% shorter than stock | 40% shorter than stock | 60% shorter than stock |
| Price | $160 | $220 | $195 |
| Compatibility | FNS Compact only | FNS Compact, some Glocks | FNS Compact, select SIGs |
Note: The Zev Fulcrum gives you adjustability but at a higher price and with some safety tradeoffs. The Timney Alpha is lighter but requires more fitting. The Apex kit hits the sweet spot for drop-in simplicity and safety retention at a lower cost.
FAQ
Will this kit work with my FNS Compact in .40 S&W?
Yes, the Apex Action Enhancement Kit is compatible with both 9mm and .40 S&W FNS Compact models. The sear and springs are identical across calibers.
Do I need to modify the trigger housing or frame?
No. This is a direct drop-in replacement. No filing, sanding, or fitting required. Just remove the factory parts and install the Apex components.
Will the trigger pull weight change over time?
Per Apex specs, the sear is hardened steel and the springs are stainless. I’ve seen less than 0.2 lbs of change after 1,000 rounds. It stays consistent.
Does this kit void my factory warranty?
Installing aftermarket parts may void the FN factory warranty on the trigger components, but it does not void the entire gun warranty. Apex offers a lifetime warranty on the kit itself.
Can I use this kit for concealed carry?
Yes. The 5.5 lb pull weight and full safety retention make it suitable for carry. Many shooters prefer it over the factory trigger for its consistency and shorter reset.
