Extra Rounds / More Style! 

We've added some design style to the new Plus Magazine Extensions by GS/Double Diamond. These attractive magazine extensions allow you to add extra rounds — up to 5 extra rounds — to your existing magazines. These combos come pre-installed with an extra power spring to feed the additional rounds consistently every time and are designed with a very innovative system to secure the base plate to the magazine body. 

The magazine 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: 
• G43X/48 - +4 9mm 
• G43 - +2 9mm 
• G19X/17/22/31/34/45/47 - +5 9mm / +5 .40cal/.357 
• G19/23/32/49 - +5 9mm / +4 .40cal/.357 
• G26/27/33 - +5 9mm / +4 .40cal/.357 
• Big Stick 9mm - +5 9mm 

Please Note: The Big Stick 9mm Option includes a Glock Factory Big Stick 33rd 9mm Magazine without the Factory +2 Extension, for a total capacity of 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.
