*NOTE: REQUIRES GLOCK OEM MAGAZINE INSERT (SP07165) FOR INSTALLATION*
Glock OEM +2 Magazine Extension – 9mm/.40 S&W/.357 SIG/.45 GAP – 50975
The Glock OEM +2 Magazine Extension (50975) is the 2026-standard factory solution for increasing the capacity and grip surface of your double-stack Glock magazines. Unlike aftermarket components that can compromise reliability, this extension is a genuine Glock Factory Part, manufactured from the same impact-resistant polymer as your original magazine body. It is designed to add two additional rounds to 9mm magazines and one to two rounds to .40 S&W, .357 SIG, and .45 GAP magazines (depending on spring tension). In addition to the fire-power boost, the extension provides a slightly longer profile, offering better leverage for magazine extractions and a more substantial grip for shooters with larger hands, especially on compact models like the Glock 19 or subcompact Glock 26.
This specific SKU (764503060762) includes the Floor Plate Extended only and does not include the internal magazine insert (floor plate semi-shelf). For a secure and functional installation, this must be paired with the Glock OEM Magazine Extension Insert (SP07165). While many users attempt to reuse their standard flat floor plate inserts, the specialized SP07165 insert is required to properly lock the extension to the magazine tube and ensure the spring tension is correctly seated. This "drop-in" upgrade is compatible with almost all double-stack Glock magazines from Gen 3 through Gen 5, making it an essential, low-cost modification for duty, competition, or defensive use in 2026.
Includes: (1) Glock OEM +2 Magazine Extension (Extension Housing Only).
