FN 509 Price Guide: What to Pay & Current In-Stock Deals

FN 509 prices depend on the suffix. Midsize, Tactical, and LS Edge are different slides. The Reflex is a different, smaller pistol.

What you are actually buying

The FN 509 is a midsize to long-slide pistol in 9mm. Midsize magazines are often 15 rounds. Tactical and LS Edge guns use longer magazines, including 17 and 24-round extensions where legal. Many 509s are optic-ready. The Tactical and the MRD models say so. A plate set may be in the box. The Reflex is the smaller FN and a different magazine.

A striker duty 9mm with an ambidextrous slide stop. The optic system and the threaded barrel are the usual reasons to pick a Tactical over a midsize.

Variants worth separating

Midsize, compact, Tactical, LS Edge, and CC Edge. Tactical is threaded. LS Edge is the long competition slide. CC Edge is the carry size. These do not share a holster.

Who it suits

A duty or home 9mm, or carry if you pick the smaller Edge. The Reflex is the micro if that is the real goal.

What to look for in a deal

Which 509, threaded or not, optic plates in the box, and magazine count. A midsize iron-sight gun is not an LS Edge. The suffix is the gun. Tactical, LS Edge, and midsize are three rows. The wider in-stock set is on FN deals. If this size is wrong, the FN SCAR is the nearby model. The category board is handgun deals.
