TACCOM Magazine Extension for 33-Round Glock Magazines

    TACCOM has introduced an aluminum magazine extension designed for the 33-round Glock magazines. It is targeted to the PCC (pistol caliber carbine) market. When added to the 33-round magazines it increases the capacity to 60 rounds! So it is a +27 extension?!

    The TACCOM extension is made of 6061-T6 aluminum. Those shown in the images are the preproduction models. The final version will have the same shape but will be black anodized. The extension will come with its own 36-coil stainless steel spring. The assembly is done by disassembling the 33-round magazine, unscrewing the extension’s 8 Allen screws, replacing the magazine spring with one that comes with the extension, clamping the new extension onto the Glock magazine floorplate flange and tightening the screws back.

    The internal surface of the extension is smooth and allows flawless movement of the cartridges and the follower. However, the transition from the extension to the magazine may cause some issues. TACCOM recommends to chamfer the inside of the bottom edge of the magazine and the outside lower edge of the follower to allow a smooth transition and avoid any possible issues.

    The TACCOM 9mm Glock magazine extension is available for pre-order at $79.95. The shipping will start around late October 2017.

    Theoretically, this extension is possible to be added to any Glock magazine. However, you’ll need a proper length spring. As people in TACCOM told me, even the Glock 17 magazine will require cutting the spring.
