FN's First Entry Into The Slim Line Sub-Compact Market

FN has a history that began in 1897, when they partnered with legendary John M. Browning producing 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 well known for designing and manufacturing machine guns such as the famous FN SCAR and FN PDW, as well as their FN polymer pistols. With clientele that include Military and Law Enforcement units world wide it is no wonder that lawful citizens have flocked towards this fantastic firearm company. FN firearms are built combat tough with pride and precision.

FN continues this heritage with their fist slim line subcompact handgun the 503. With an overall length of just 5.9" and a width of 1.1" this handgun is smaller than most pistols in the same class. An all metal trigger crisply breaks at a weight of 5lbs and low profile iron sights reduce the risk of being snagged for a smooth easy draw. The 503 Also utilizes the same sight dovetail of the larger 509 pistols making after market replacements easy to find. With a reputation of dependability and performance the FN 503 is the obvious choice for quality when choosing a subcompact slim line 9mm handgun.
