FN America 509
About the FN America 509
The FN America 509 Midsize is the baseline model in FN America’s 509 line, a 9mm striker-fired pistol with a 4" barrel, 15-round capacity, and an optics-ready slide cut, offered in flat dark earth. It splits the difference between FN America’s compact and full-size 509 variants, making it a common choice for concealed carry that doesn’t sacrifice as much capacity. Miami Guns can compare it side-by-side against the Compact and Fullsize 509 models to help you pick the right frame size.
