Description
This Tyrant CNC magazine extension works with Glock 19, Glock 23, and Glock 26 magazines (Gen 4 and Gen 5), giving you a straightforward way to boost your capacity without any permanent modifications. The matte gold finish stands out while staying functional, and the aerospace-grade aluminum construction is tough enough for range use, competition, or carry setups.
NoBak Retention System and Tool-Free Install
The whole appeal here is how fast this goes on and comes off. Tyrant's retention plunger technology lets the extension slide right onto your mag base in about 10 seconds flat, and you don't need any tools at all. If you ever want to remove it, just push the plunger down and slide it off. That's it. This beats having to mess with screws or springs, especially if you're switching between different mag setups.
Built for Control and Drop-Free Performance
Because it's machined from aerospace-grade aluminum, this extension adds some real weight to the base of your magazine. That weight helps your mags drop free consistently when you're doing reloads, which matters whether you're running drills at the range or in a self-defense situation. The machined inlay also gives you a better grip when you're grabbing the mag, making your reload motion faster and more reliable. Tyrant includes a USA-made power spring with 10% more tension than factory springs, so the extension reliably feeds rounds without any hiccups.
Capacity and Compatibility
You get plus 5 rounds on 9mm Glock 19 magazines, and plus 4 on .40 cal Glock 23 magazines. The extension also fits magazines that share the Glock 19/23 lower half geometry, which means it works with Glock 26 mags as well. It's designed for Gen 4 and Gen 5 platforms and maintains compatibility with Gen 6 models that use standard Glock magazine dimensions.

Frequently Asked Questions
Does this extension work with all Glock 19 magazines?
It's designed for standard Glock 19 and Glock 23 magazines (Gen 4 and Gen 5), and works with aftermarket options. However, it doesn't fit Magpul PMAGS. If you're using OEM Glock magazines or most aftermarket brands, you're good to go.
How long does installation actually take?
The whole process takes about 10 seconds or less. Slide it onto your mag base and you're done. The NoBak retention plunger does all the work for you, so there's no fussing with tools or springs. Removal is just as quick if you ever need to swap it off.
Will this add too much weight or change how my magazine handles?
The extension only adds about 1.3 ounces, which is minimal. If anything, that extra weight at the base helps your magazines drop faster and more reliably during reloads. The machined inlay actually improves your grip on the mag, making it easier to grab and manipulate.
What's included in the box?
You get the mag extension itself and a USA-made power spring that's 10% stronger than factory springs. This upgraded spring comes pre-loaded so you can install the extension and start using it right away without any other prep work.
