What is a Magazine Extension?

A magazine extension is an accessory that attaches to the base of your firearm's magazine, increasing its capacity and enhancing its functionality.

Combining the power spring and the extension creates a seamless upgrade for your Sig P320, enhancing its overall performance and reliability.
