Apex Announces 5.00″ LongSlide For FN 509

Apex Tactical Specialties is pleased to announce its much-anticipated 5.00″ LongSlide for the FN 509 will be available for pre-order on Tuesday, October 27th.

Designed by Apex’s engineering team and manufactured at the company’s state-of-the-art Arizona manufacturing facility, the new custom longslide assembly is packed with features. The fully machined slide is optics ready with the RMR pattern cut. It’s lightened to mimic factory slide mass with both front and rear cocking serrations. The sight dovetails accept FN sights.

The slide comes fully assembled with Apex’s Heavy Duty Striker, the Apex Failure Resistant Extractor and an Apex premium hammer-forged 9mm barrel with a 1:10” twist rate. Customers can select between a standard length 5.00” barrel or a 1/2-28 threaded barrel with thread protector and captive O-ring. All internal slide components and a yellow recoil assembly are included.

While red dot ready, the slide is shipped with either standard height XS 3-Dot night sights or suppressor height sights (black/black), depending on the customer’s preference. The slides will be available in stainless or black Melonite finish.

This slide is complete, fully assembled and ready to shoot.
