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: Shiny Aluminum
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

Goliath Glock Plus 20 Basepad
I am extremely happy with this massive improvement in the stock 31 round Glock magazine. Shooting PCC in both USPSA and outlaw 3 gun matches I have found no better. Thank you Taylor Freelance...and yes, you get what you pay for!
