Extra Rounds / More Style!
We’ve added some design style to the new Magazine Extensions by GS/Double Diamond. These attractive magazine extensions allow you to add up to 5 extra rounds to your existing magazines. Each comes with an extra power spring to feed the additional rounds consistently every time and is designed with a very innovative system to secure the base plate to the magazine body.
The magazine base plate inserts are also designed for a universal fit allowing for custom color combinations, and increased style and functionality, available separately here.
We encourage you to watch the video for a complete installation demonstration.
Available for the following models:
• G17/22/31 – +5 9mm / +4 .40cal/.357
• G19/23/32 – +5 9mm / +4 .40cal/.357
• G26/27/33 – +5 9mm / +4 .40cal/.357
• Big Stick 9mm – +5 9mm
Please Note: The Big Stick 9mm Extension is designed to replace the factory extension on the Glock Factory Big Stick 33rd 9mm Magazine. This extension includes an extra power replacement spring and will increase your capacity to 36 rounds.
Also Note:These extensions will work with most aftermarket magwells. However, the retaining pin will need to be adjusted to prevent scratching/marring of your magwell.
Customize your look and style with our interchangeable baseplates, available separately here!
Also available in a +2 model for the Glock 43 found here.
