Description
The Tyrant CNC Hellcat extension adds three rounds of capacity to compatible Hellcat magazines, giving you more ammo on hand without the bulk of a larger frame. Built from 7000-series aluminum and CNC machined for precision, this is a straightforward way to extend your firepower for competition, range time, or everyday carry.
Design and Materials
Typical mag extensions can be finicky, but this one keeps things simple. The extension uses your existing magazine spring, so there's no hunting for additional parts or making adjustments to function reliably. The hardcoat anodized finish handles daily use without wearing through, and the black color blends seamlessly with most Hellcat setups. The extension follows the Hellcat's slide serration pattern along the sides, so it doesn't look like an afterthought on your magazine.
Installation and Compatibility
There's no mystique here. Drop it on and you're done. No special tools, no gunsmithing required. The extension works with 11, 13, and 15-round Hellcat magazines, plus the Hellcat Pro's mags. Tyrant CNC's NoBak springer plunger technology keeps it secure even when you're pushing things hard at the range. Just note it doesn't fit 10-round magazines.
What You Get
You're picking up a single extension that takes your standard Hellcat mag and adds three rounds. Most people grab a couple so they have extended capacity options across their mags. It's a practical upgrade for anyone running Hellcats who wants more ammunition available without going to a larger, less concealable firearm.

Frequently Asked Questions
Will the Hellcat magazine extension work with all my Hellcat magazines?
It works with the 11, 13, and 15-round magazines for both the standard Hellcat and Hellcat Pro. The only magazine it won't fit is the 10-round compact mag. If you're unsure which mags you have, check the round count on the magazine itself.
Do I need to replace the magazine spring or make any modifications?
No modifications needed. The extension is designed to work with your existing OEM spring that came in the magazine, so installation is genuinely simple. Just swap the baseplate and you're set.
How long does installation take?
A few minutes. You don't need any special tools or gunsmithing knowledge. If you've ever swapped a magazine baseplate before, you'll have no issues. Even if you haven't, it's a straightforward process.
Will the extension stay put if I drop my magazine or handle it roughly?
Yes. Tyrant CNC's NoBak springer plunger technology keeps it secure even under rough handling, so it won't come loose from heavy use at the range or in practical drills.
