Striker Components Kit

If you’ve lost a factory striker spring cup or the spring itself during a disassembly or cleaning, the Striker Components Kit is exactly what you need to get your pistol back in working order. Instead of hunting down small OEM parts or buying a whole new striker assembly, this kit gives you the two most commonly misplaced bits: the spring cup and the striker spring. Both pieces are machined from steel and heat-treated for long-lasting durability—no more worrying about plastic cups cracking or springs taking a set over time.

Will this fit my gun?

This kit is designed as a direct replacement for factory striker components in the following models:

• FN FNS series (FNS-9, FNS-40)
• FN FNX series (FNX-9, FNX-40, FNX-45)
• FN 509 series (all variants)
• FN High Power (2022 and later models)

If you’re unsure whether your specific pistol uses these parts, give us a call or drop a note—we’re happy to help you confirm compatibility before you order.

Install difficulty

Difficulty: 2 out of 5 — Simple swap if you’re comfortable field-stripping your pistol. Tools needed: a punch or small screwdriver to depress the striker, and a pair of tweezers or needle-nose pliers for the spring cup. If you’ve never replaced a striker spring before, we have a step-by-step install video on our site that walks you through it in about 5 minutes.

Frequently asked questions

Will these parts work in my FN 509 Compact?

Yes, the Striker Components Kit fits all FN 509 models, including the Compact, Tactical, and MRD versions. The spring cup and spring dimensions are the same across the line.

Do I need to replace the entire striker assembly or just these parts?

Just these parts. The kit is meant to replace the two most commonly lost components—the spring cup and striker spring. Your existing striker body and other internals stay in place unless they’re damaged.

Is this the same quality as the factory parts?

Yes, and in some ways better. The steel cup is more durable than the factory plastic cup, so it won’t crack or deform over time. The spring is heat-treated to hold its tension longer than many OEM springs.
