No magazine spring lasts forever - if you shoot enough, sooner or later, you'll need to replace your magazine spring. You'll never have to worry about this with a Shield Arms Magazine Extension, because if you wear out your spring shooting, simply send it back to us and we'll send you a new one for free.
Send your magazine spring to:

*Be sure to include your name and return address, and the magazine extension model.
