The FN 509 Compact delivers full-size performance in a concealed carry package, featuring a 3.7-inch barrel and dual magazine capacity options. This striker-fired pistol combines FN's military-grade manufacturing with civilian practicality for both duty and personal protection applications.
What Makes This Different
Unlike standard compact pistols that sacrifice accuracy for size, the FN 509 Compact maintains a full 3.7-inch barrel length while reducing overall frame dimensions. The cold hammer-forged barrel delivers match-grade accuracy typically found in full-size competition pistols. FN's proprietary surface treatments provide 75% greater corrosion resistance compared to standard Melonite finishes, extending service life in harsh environments.
