Faxon Firearms Modular Magazine Extension Features The Faxon Firearms Modular Magazine Extension is machined from 6061 T6 aluminum giving it the strength and dimensional stability needed to stand up to repeated magazine drops and reloads. A Type 2 anodized finish adds corrosion and wear resistance so the extension keeps its fit and function through extended range sessions and duty carry alike. Built specifically for the Glock 19 it adds 5 additional rounds of capacity turning a standard-capacity magazine into a higher-round-count option without the bulk of a full replacement magazine. That extra capacity can matter for competition stages home defense or simply reducing reload frequency at the range. The anodized black finish matches factory Glock finishes keeping the magazine s appearance uniform while adding the functional upgrade. Because the extension is part of Faxon s modular system it reflects a design philosophy built around adaptability rather than a single fixed part. The aluminum body is engineered to resist the stress placed on the magazine s base during tactical reloads and magazine changes. For Glock 19 shooters who want more rounds per magazine without compromising reliability the Faxon Firearms Modular Magazine Extension is a straightforward durable upgrade.
