If you shoot an FN 509 regularly, you know the factory striker can wear out faster than you’d like—especially if you do a lot of dry fire practice. This durable striker is a direct drop-in replacement built to handle the abuse. It’s been tested and certified for over 125,000 dry strikes on an empty chamber, so you can train hard without worrying about parts failure. The improved sear catch geometry also gives you a crisper trigger break, making your shots more predictable at the range or in competition.

Frequently asked questions
Do I need to buy anything else to install this?
You’ll reuse four parts from your factory striker: the striker spring stop, spring stop pin, return spring, and spring guide. Everything else you need is in the box, including the buffer and removal screw.
Will this striker work with my factory trigger?
Yes, it’s designed as a direct replacement for the factory striker and works fine with the stock trigger. For an even crisper break and slightly lighter pull, you can pair it with an aftermarket trigger kit.
Is the buffer reusable if I swap strikers later?
Yes, the buffer is a durable component that can be transferred to a new striker if needed. Just make sure it’s seated properly in the slide channel each time.
