FN 509 Compact 9mm 3.7″ FDE | FN 66100819

The FN 509 Compact from FN America / FN Herstal is a compact, striker-fired semi-automatic pistol with a 3.7-inch barrel and Flat Dark Earth finish. It is designed to offer full-sized performance in a more concealable package while retaining features intended to improve control and handling. The package as supplied includes two magazines and a soft pistol case. For a slide-mounted red-dot that pairs well with this platform and stays well under $1,000, consider a Trijicon RMR Type 2 for its durability and low-profile footprint.
