Looking to speed up your reloads? These FN 509 magazine extensions are a great upgrade for your pistol. Not only do they enhance your grip on the magazine when doing mag changes, the extra weight from the solid aluminum base pad also ensures that your magazine falls free.Designed with the shooter in mind, all sharp corners and edges have been rounded off to ensure that there are no “hot spots” that result in pain when inserting the magazine.
Manufactured in Canada with Canadian magazine capacity laws in mind, these mag base plates add no extra capacity so there is no need to re-pin your mags. Simply remove the factory base pads and slide these ones on!
