Apex Tactical Action Enhancement Kit – FN FNS / FNS Longslide (Model 119114)

If you’ve got an FN FNS or FNS Longslide made after 2014, you already know the factory trigger leaves a little something on the table. That’s where this kit from Apex Tactical comes in. It’s a direct drop-in replacement for the stock polymer trigger, trigger bar, and sear. No filing, no fitting, no sending the slide off to a guy in another state. You open the box, swap the parts, and you’re back in business with a trigger that actually feels like it belongs on a serious pistol.

Apex’s patent-pending design drops the pull weight right around the 5.5-pound mark. That’s a solid middle ground—light enough to shoot accurately at the range or in competition, but still heavy enough to keep your head in the game for duty or home defense. The uptake is smooth, the break is crisp, and there’s none of that gritty, stacking nonsense you get from the factory plastic parts. The whole kit is machined from aluminum and finished in black, so it’ll hold up to regular use without wearing out or feeling mushy after a few hundred rounds.

For California shooters, this kit is a practical upgrade. You’re not permanently modifying the firearm—just swapping in better parts. That means you keep your original bits if you ever need to return to stock. And because it’s a drop-in, you don’t need a gunsmith. A little patience, a punch, and a clean workbench are all you need.
