FN 509 Compact 9mm 10-Round Magazine

This factory FN® magazine is the best available for your 509 Compact! Made from stainless steel for durability and corrosion resistance, this magazine is built tough enough to handle daily carry or duty. The black finish provides a glare-resistant, low-profile aesthetic. A high-visibility follower makes it easier to identify an empty magazine from a loaded one, and the ambidextrous witness holes ensure you always know how much ammunition you have left. This magazine features an extended baseplate to offer more grip area without compromising concealability. The impact-resistant polymer is also textured to match the frame.
