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.

Since 1991, Warne has been well known and trusted in the industry for their scope mounts. As Warne expanded, they brought the same quality and dependability you love into their accessories. Each product is "built by shooters, for shooters."
