Glock Factory Original Magazine Catch Reversible Extended Fits 9mm Luger|.40|.357 Gen4/Gen5 PACKAGED

If you've got a Gen4 or Gen5 Glock and need to replace a worn magazine catch or swap to a southpaw setup, the Glock Factory Original Magazine Catch is the straightforward choice. This is genuine Glock OEM hardware—not an aftermarket approximation—manufactured to the exact same specs and tolerances as the factory part that came in your pistol. It fits 9mm Luger, .40 S&W, and .357 SIG chambered Gen4 and Gen5 Glocks, and the reversible design means you can configure it for either right- or left-hand operation depending on your needs.

Factory parts matter when it comes to reliability. Glock uses the same materials and manufacturing process for replacements as for original production, which means zero guesswork about fit or function. Whether you're fixing a mag catch that's seen hard use, building a dedicated competition or training gun, or simply want a spare on hand, OEM parts eliminate compatibility questions and keep your pistol running exactly as designed.

This part comes packaged and ready to install. It does not fit Gen 1–3 Glocks, so verify your pistol's generation before ordering. If you're new to Glock internals or want to be certain your firearm is covered, consult your owner's manual or reach out to us—we're happy to confirm fitment.
