These FN 509™ mags have a corrosion-resistant stainless steel body with a brightly polished interior to help the ammo stack flow smoothly, with a tough matte black exterior finish, and witness holes numbered 4 through 17 (4 through 10 on the 10-round model).

  • Matte black polymer base pad to protect magazine if ejected onto hard surfaces
  • High-visibility, anti-tilt follower of bright orange polymer
  • For FN 509™ pistols chambered in 9mm Luger only
  • NOTE: Will NOT work in FNS TM or FNX TM pistols
  • Available in full 17-rd capacity or 10-rd for folks living in capacity-restricted jurisdictions
