MAG SLEEVE FN 509M 9MM 17RD

Description

This is a FN America / FN Herstal 17-round 9mm magazine for the Mag Sleeve.

This is a full-size standard-capacity magazine, the usual choice for duty and range use. Magazines are consumable: springs and followers wear before the body does, so buying spares and rotating them is cheaper than chasing feed problems later.

Several states and cities cap magazine capacity, and those limits change. Check your state and local rules before ordering – we ship to your address or your dealer, but we cannot ship a magazine somewhere it is not legal. Magazines ship directly to you with no FFL transfer.
