Product Description
Wield 51+1 rounds from your Glock pistol-caliber carbine! Unprecedented strength: rigid design absorbs abuse and hard knocks. We can STAND ON IT! (See video.) Quick-release base allows for easy cleaning (without taking the mag apart) "Sword-like" grip provides positive control when inserting -- you won't slip in a critical moment! Includes custom super-length spring. Due to state department restrictions we cannot ship this part internationally. California customers with LE or Hi-Cap credentials, call us directly to order.
Weight: 5.7 ounces
Material: Aluminum
Color: Black
NOTE: Because of a combination of factors, we build our basepads slightly "short" for best reliability. As a result, they will run properly with ammunition loaded to 1.125" overall or less. That's a typical length for 115- and 124-grain loads, but some (notably, Winchester 115 RN) will go out all the way to 1.160".
HINT: If your extension will take 35 rounds and then becomes unreliable (or sticks), check the length of your ammunition! Question? Give us a call and we can explain.
NOTE: Our friend Josh Froelich has posted a great video showing how to "tune" your Glock mags along with our Goliath magazine extensions for flawless operation. Thanks Josh! https://youtu.be/WjCiFXlnnyE

The only extension I trust
I’ve used several of my friends big stick mags. This one is the only one that functions consistently. You do have to dremel down the back of the Glock mag a bit to get the follower to move smoothly through the transition, but once done correctly there are zero issues. Highly recommended.

Goliath Glock +20 Basepad
Love the product. Glad to have the extra round count. Product was easy to install on Glock 33 9mm mag. Hardest part of installation is getting the factory +2 basepad off the original Glock 33 rd mag.
