Description
If you're running an H&K VP9, VP40, or VP30, this Tyrant CNC extension gives you a solid five-round capacity bump with a design that actually works. The whole thing is machined from aerospace-grade aluminum and finished in gold, so it sits flush with your magazine while giving you way more to grip when it counts.
Installation and Retention Plunger Design
What makes this extension stand out is how stupid simple it is to install. The retention plunger technology means you just slide it onto your magazine and you're done in about ten seconds flat. No tools, no gunsmithing, no standing around trying to figure out what goes where. When you want to swap it off, you push the plunger down and slide it off just as easy. That means you can move extensions between mags without any hassle.
Ergonomics and Grip Benefits
The machined profile continues right from your VP9's handle, so the ergonomics match factory exactly. You're not getting some blocky, aftermarket feel in your hand. The added aluminum weight helps your magazine drop fast on reloads, which matters whether you're drilling at the range or working through transition drills. The gold finish isn't just looks either, it gives you a more positive purchase on the magazine base when you're moving fast.
Made to Last
These are manufactured in the USA with a flawless finish and backed by a lifetime warranty. The construction is solid enough to handle repeated mag drops and everyday carry wear. Whether you're a competitive shooter looking for reload speed or someone who just wants more rounds on tap, this extension does the job without making your magazine look like some Frankenstein build.

Frequently Asked Questions
Will this magazine extension work with my 17-round H&K VP9 magazine?
This extension works best with standard-capacity magazines and 15-round VP9 magazines. It's not compatible with 10-round magazines or magazines with red or orange followers, so check your magazine type before ordering. If you have a magazine you're unsure about, reach out and we can help confirm compatibility.
How many rounds can I actually load with this extension?
The extension is designed to add 5 rounds to your magazine capacity. Some users report that actual capacity can vary by a round or two depending on how tightly you load it and how much the magazine spring is broken in. Most get the full five rounds without issue after a few uses.
Do I need to disassemble my magazine to install this?
No. The Tyrant CNC extension uses a proprietary retention plunger system that lets you slide it straight onto the bottom of your magazine without any disassembly. Installation takes less than 10 seconds and requires absolutely no tools.
Can I easily remove and swap this between magazines?
Yes. The retention plunger design makes removal just as fast as installation. Simply push down the plunger and slide the extension off. You can then slide it onto another compatible magazine in seconds, making it easy to move the extension between your VP9 mags as needed.
