Description
The Tyrant CNC TD-G48MAGEX-BLK magazine extension was built for people who carry slim Glock pistols but want more firepower without bulking up their gear. It attaches to the base of your 10-round G43X or G48 factory magazine to add 4 rounds of capacity, bringing you from 10+1 to 14+1. The piece is machined from aerospace-grade aluminum and finished in subdued matte black.
Installation Is Genuinely Simple
Tyrant uses what they call retention plunger technology to make this extension slide onto your magazine in under 10 seconds. No special tools, no fussing with tiny tabs, no gun smith work needed. If you ever want to remove it, you just push the plunger down and the base plate slides right back off. Everything comes with a 10% power spring included so your magazines feed and drop consistently from day one.
What Makes The Handling Better
The added weight from the aluminum construction helps your magazines drop faster and more reliably during reloads. The knurled design on the extension gives your fingers something secure to grab even if your hands are sweating or wet. A lot of carry pistol owners appreciate that the extension also prevents you from pinching your hand between the magwell and magazine during rapid reloads. The whole thing weighs 1.3 ounces and extends just 1.15 inches, so your carry gun stays reasonably compact.
Built To Last
Tyrant CNC machines all of these in the USA. The aerospace aluminum gets bead blasted and anodized for both durability and that clean matte finish. The extension is designed to work exclusively with Glock's OEM 10-round 43X and 48 magazines, not aftermarket or other brands. Everything carries a lifetime warranty, so if something goes wrong, Tyrant has you covered.

Frequently Asked Questions
Do I need any special tools to install this magazine extension?
No. The entire installation happens in 10 seconds or less without tools. Tyrant's retention plunger technology lets the extension slide straight onto your magazine. To remove it later, just push the plunger down and the base plate slides right off.
Will this extension work on my aftermarket Glock 43X or 48 magazines?
No. This extension is designed specifically for Glock OEM 10-round magazines for the 43X and 48. It will not work on aftermarket magazine bodies or older factory magazines from other Glock models.
Does this extension add too much bulk for concealed carry?
The extension adds only 1.15 inches of length and 1.3 ounces of weight, keeping your magazine profile relatively compact. Many people use it as their backup magazine during carry since the added weight actually helps with faster magazine drops during reloads.
What's included in the box?
You get the magazine extension itself and a 10% power spring. The spring is slightly stronger than the factory spring and is included to ensure reliable feeding and magazine drops right out of the box.
