More on the FN 509 semi-auto 9mm (VIDEO)

FN USA’s booth at the NRA Annual Meeting in Atlanta featured their newly released FN 509 polymer framed full-sized pistol front and center.

Based on their FNS Compact platform, the 17+1 capacity handgun was beefed up to meet rigorous military requirements that saw more than 1 million rounds fired in reliability, ammunition compatibility, and durability testing.

Overall length is 7.4-inches and the FN 509 tips the scales at 26.9 ounces.
