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

Goliath magazine extension

Posted by Greg on Dec 28th 2024

Highly disappointed I can only fit 39 rounds of factory ammo in this. I don't think I should have to purchase particular ammo to make this device work.

Goliath +20 Basepad for Glock

Posted by SP on Dec 21st 2024

I shoot action matches that include some steel. At times I need more than 40 rounds. I use original Glock mags and needed an extension. I found your product to be of higher quality than another well known brand. So far I am pleased.

Goliath 20 round extension

Posted by Dave on Jul 25th 2024

This is the ultimate extension for competition shooting. It is 100% reliable in my AR9 PCC. I had been using TT extensions but they never ran 100% ,which is unacceptable in USPSA competition. The Taylor Freelance Goliath extension is the gold standard!

Goliath plus 20 basepad for glock

Posted by Tom Burke on Apr 17th 2023

Nice piece, looks awesome, quality is good, went together easy!! It did have some weird smudges on the front ridged section almost like it had been sanded on. Overall good piece a little spendy but hey that’s just a sign of the times!! Thanks Taylor Freelance!!! I’m excited to try it out!!!

Goliath Plus 20

Posted by RYAN DAVIS on Apr 6th 2023

I did some research and the Goliath, It had great reviews. I purchased the Plus 20. It was an easy install. I installed it on a Glock 31 round magazine. As I went to load the rounds, I couldn't load more than 33 rounds in it. The Based pads interior is not large enough to allow the rounds down inside the Basepad. The inside spacing is too tight and the rounds bind up and get stuck. It was suppose to allow the addition of 20 more rounds but could only load 2 more than before I add the Goliath 20. Unless the rounds that you are using are really short (the overall cartridge length) This Magazine extender does not work with 124gr or 147gr Rounds. They should have tested this or told me this before I ordered a 20 round magazine extender that only allows the addition of 2 more rounds! RESPONSE: Ryan, give us a call. There's something wrong with your setup -- should be an easy fix.

The only extension I trust

Posted by Kyle on Jan 3rd 2021

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.
