Apex Durable Striker for FN 509

The Apex Durable Striker for the FN 509 Series pistols is a direct drop-in replacement for the factory striker.  This striker has been tested and certified for dryfire on an empty chamber up to 100k strikes. You read that right - certified for 125,000 dry strikes. This Striker is the culmination of over 3 years of continued R&D and testing. Through the R&D process, we’ve cataloged more than 1 million dry fires to prove out the design. 

The sear catch geometry has been improved to produce a crisp trigger break while maintaining sear to striker engagement. 
These strikers are machined from heat treated tool steel and finished in Nickel Teflon for ultimate lubricity and wear resistance. 

The Apex Durable Striker includes a proprietary buffer (to be installed into the slide) which dampens the shockwave created by dryfiring. A 6mm x 60mm Socket Head Cap screw is included for use as a removal tool for cleaning and maintenance needs. 

Installation requires the following factory striker components:

(These are factory components which can be removed from your factory striker and used with ours).

• striker spring stop
• striker spring stop pin
• striker return spring, and
• striker spring guide.

Expected Results: 
1) Direct drop-in replacement for the factory striker 
2) Extremely long service life (Rated for over 125,000 dry fires) 
3) Crisp trigger break 

When installed in conjunction with an Apex AEK Trigger Kit, the trigger pull weight averages 5.5lbs. 
When installed with the FN factory trigger system, the trigger pull weight averages 6.5lbs.
