Glock 17 Magazine Extension Kit – 9mm – +6 Round – Blue

Designed to fit all of the Glock 17 models from Gen 1 through and up to the current Gen 5 models. Each unit is fully machined from a solid billet of aircraft-grade aluminum that is fully hard coat anodized and set up for a lifetime of use. The unique design fits the stock mag body with no additional mods, hardware other than the enhanced extended spring kit. Made in the USA.

HKP highly recommends using a magazine loader when loading ammunition into our extended magazines due to increased spring tension versus factory.
