The Apex Tactical Durable Striker for FN 509/503 (Apex part number 119-186) is a direct drop-in replacement for the factory striker on FN 509 series pistols, built to hold up to far more use than a stock striker is rated for. This striker has been tested and certified for dry-fire on an empty chamber up to 100k strikes, and Apex is specific that the real number is 125,000 dry strikes. That durability is the result of over three years of continued research and development, during which Apex cataloged more than one million dry fires to prove out the design before bringing it to market. For competitive shooters and anyone who trains heavily with dry-fire practice, that kind of documented longevity matters.
