WARNE Glock 19/23 Magazine Extension Black

This Warne Magazine extension is a must have for your Glock 19 whether you are a competition shooter or a recreational one. This extension drops free and fast thanks to the added weight from being CNC machined out of aerospace grade aluminum. Each extension comes with a new spring to keep your rounds tight in the magazine. The set screw in the back of the extension helps securely hold it on the magazine no matter what you throw at it.
