FN 509 Compact Features

The FN 509® is built on the proven architecture of the FNS™ Compact, FN made changes internally and externally to meet the rigorous performance standards of the MHS requirements and further developed the platform into the FN 509® with the help from industry experts. Over the course of development, the platform has been tested extensively for reliability, ammunition compatibility and durability – totaling more than one million rounds. The slide is easily racked, contains combat-style sights, has an external extractor, and a loaded chamber indicator. The enhanced grip textures with interchangeable backstraps enables faster follow-up shots in all conditions.
