FN’s rich history dates back to 1897 when they collaborated with the legendary John M. Browning to produce iconic firearms such as the .30 Cal Machine Gun, Browning Automatic Rifle, Browning Hi Power, 7.65 Auto Pistol, and the Auto-5 semi-auto shotgun. Today, FN is renowned for designing and manufacturing cutting-edge firearms like the FN SCAR and FN PDW, along with their FN polymer pistols. Trusted by military and law enforcement units worldwide, FN firearms are synonymous with durability, precision, and pride.

Continuing this legacy, FN introduces the FN 503, their first slimline subcompact handgun. With an overall length of just 5.9″ and a width of 1.1″, this pistol is smaller than most in its class. The all-metal trigger breaks crisply at 5lbs, while low-profile iron sights minimize snagging for a smooth draw. The FN 503 shares the same sight dovetail as larger 509 pistols, facilitating easy aftermarket replacements. Renowned for its dependability and performance, the FN 503 stands out as the top choice for those seeking a quality subcompact slimline 9mm handgun.
