The 509 is FN's striker fired 9mm, and the 509T is its tactical version. We carry two parts.

Red dot mount

Outer Impact's type C takes the rear sight's place on a slide without a cut, for RMR, RTS or Docter based dots.

Magwell

For the 509T, Toni System offers a polymer magwell combined with a backstrap, widening the opening for quicker reloads.
