TMC Oversize Magazine Release Button – 4×40 TPI

The TMC Oversize Magazine Release Button helps you reload faster and with more confidence. Its larger size makes the button easier to find and press. As a result, magazine changes feel smoother and more controlled every time.

Faster Reloads with Better Control

First, the oversized design gives your thumb a larger contact area. Because of this, you apply steady pressure without slipping. Next, the improved grip reduces missed presses during reloads. Therefore, you stay focused on shooting instead of fumbling with controls.

Lightweight and Strong Construction

TMC machines each button from aircraft-grade billet aluminum. This material is both strong and lightweight. Because the button weighs very little, it does not affect balance. In addition, CNC machining ensures precise threads and a consistent fit.

Clean, Low-Glare Finish

After machining, TMC bead blasts the surface. As a result, the button has a clean matte finish. This finish reduces glare and matches well with custom or competition pistols. Moreover, it adds a professional look to your build.

Designed for Threaded Magazine Releases

This release button requires a magazine catch threaded 4×40 TPI. Therefore, it works with STI 2011 pistols and other compatible platforms. Before installation, confirm that your magazine release uses the correct thread pattern.

Ideal for Performance Builds

Competition shooters benefit the most from this upgrade. However, any shooter who wants faster and more reliable reloads will notice the difference. Because installation is simple, this button makes an easy improvement for tuned pistols.
