Thank you for trusting us on your Glock 43 Magazine Extension. This part not only adds two more needed rounds to your Glock, but also gives you a better grip making the gun more shootable and more stable. The part is cut from Aerospace aluminum and hard anodized for a good looking and durable finish.


Find a punch or any tool that you can insert to press down the pin that holds in place your OEM Glock Magazine base plate.

What you need to accomplish by pressing down that pin is to compress the spring.

Once you have the spring compressed, use the same punch or tool to apply pressure and start sliding the base plate forward. This is a little harder than normal to do so make sure you are putting the right amount of effort.


Keep sliding forward, keeping the spring under control so it doesn’t go flying. Now you are going to be able to fully remove the spring.


On the Glock magazine, you are going to notice some little wings or squares. They are there to help you retain the OEM base plate in place.

Your Barracuda Tactical Magazine Extension doesn’t need them so you can cut them off for an easy install of them.


Press down the spring and start sliding your Barracuda Tactical Magazine Extension in place.

Do not worry; it is going to be locked in place.

At this point your Barracuda Tactical Magazine Extension has been Installed.
