The Rival Arms Aluminum Extended Magazine Release for Glock 43X/48 is a precision CNC-machined upgrade designed to make reloads faster and more intuitive on compact Glock pistols. Built from aluminum in a single-piece design, this extended mag release gives your trigger finger a larger, more accessible target—a meaningful improvement if you run your subcompact Glock for concealed carry, home defense, or the range. The extended lever translates directly to quicker magazine changes under stress, and the robust engineering means you get reliability without adding weight or complexity.
Installation is straightforward and requires no gunsmith—just swap out your factory mag release in minutes. The package includes a new mag release spring, so you have everything needed for a clean install. CNC machining ensures tolerances are tight and consistent, which means smooth actuation and longevity you can count on.
If you carry a 43X or 48 and find the factory mag release cramped or slow, this upgrade pays for itself the first time you need a fast reload. It's a small change that sharpens the gun's ergonomics and your own performance.
