Description
The Tyrant CNC Glock 43X/48 magazine extension in gold is engineered to solve one of the most common complaints about compact carry guns—limited ammunition capacity. This extension adds four rounds to your factory magazine, taking you from 10 to 14 rounds per mag without adding bulk to your carry gun.
How the Tyrant extension stands out
Unlike other magazine extensions that require disassembly tools or complicated installation procedures, Tyrant's retention plunger technology lets you slide this onto your magazine base in seconds with zero tools. The whole process takes about 10 seconds and there's no special knowledge required. Need to swap it off your mag? Just push the plunger and it slides right off, giving you full flexibility to mix and match mags depending on your needs.
Built for reliability and control
Machined from aerospace-grade aluminum, the extension adds just enough weight to help your magazines drop free naturally during tactical reloads. The gold finish over the CNC-machined surface looks clean while maintaining durability through regular use. You get a 10% power spring included that's tuned to work with the added capacity—this spring compression supports reliable feeding of all four extra rounds and helps lock the slide back on the last round.
The knurled grip surface on the extension gives you better purchase when handling magazines, which makes faster reloads possible in real-world conditions. The compact profile means your gun stays concealable even with the extended magazines loaded. Manufactured in the USA with meticulous CNC precision, every extension is finished to exacting standards.

Frequently Asked Questions
Does the Tyrant extension work with all Glock magazines?
No, it only works with Glock 43X and 48 OEM 10-round magazines. It won't fit other Glock models or aftermarket magazine bodies. This specificity is actually what makes it such a tight, reliable fit on the mags it's designed for.
Will I need any tools to install this extension?
Not at all. Tyrant's retention plunger technology lets you slide this onto your magazine in about 10 seconds without any tools. You can remove it just as easily by pushing the plunger and sliding it off.
What's the purpose of the included power spring?
The 10% power spring is tuned to handle the extra rounds stacked in the extended magazine. It maintains reliable feeding throughout the mag capacity and ensures your slide locks back when you fire the last round, just like your factory mags do.
Will the extended magazine still fit in my holster?
The extension extends below the factory basepad, so some holsters may require adjustment or may not accept the magazine fully. Test fit before carrying. The low-profile design means it doesn't add excessive bulk compared to other +4 extensions on the market.
