Description
The Tyrant CNC magazine extension is built for M&P owners who want more magazine capacity without complications. This piece threads onto your existing magazine to add 5 rounds while improving the way your gun sits in your hand.
Quality Materials and Finish
Machined from aluminum and finished in red, this extension stands out both functionally and visually. The red finish gives you a quick way to identify extended mags at a glance, and the aluminum construction keeps things lightweight without sacrificing durability.
Better Grip and Magazine Control
Adding length to your magazine means more surface area for your pinky and ring finger. For those with larger hands or anyone who finds the full-size M&P grip a bit slim, those extra inches make a real difference in how naturally the gun points and how much control you have through the trigger press. The grip improvement is one of the most underrated benefits of a quality mag extension.
Compatible with Full-Size M&P Frames
This extension works with both the M&P 1.0 and 2.0 full-size frames in 9mm and .40 S&W. Installation is straightforward, and you don't need special tools or extensive gunsmithing to get running. Tyrant CNC applies the same precision machining standards they use across their entire line, so fit and finish match what you'd expect from a premium upgrade.

Frequently Asked Questions
Will this magazine extension work with my M&P Compact or Shield?
No, this extension is designed specifically for full-size M&P frames in the 1.0 and 2.0 generations. Compact and Shield models use different magazine dimensions, so a full-size extension won't be compatible. Tyrant CNC makes dedicated extensions for those models.
How does installation work?
The extension threads onto the base of your existing magazine where the factory base pad screws on. You'll need to remove the original base pad, thread on the extension, and reinstall the retaining hardware. It's a straightforward process that takes just a few minutes without special tools.
Does the red color matter beyond looks?
The red finish makes extended magazines instantly recognizable in your magazine carrier or safe, which helps you grab the right mag for the job. Beyond that, the color is purely aesthetic. The red aluminum offers the same durability as other colors Tyrant CNC offers.
Can I use this with pre-ban or other older M&P magazines?
This extension works with standard M&P full-size magazines. Since it threads onto the base pad, as long as your magazine has a removable base pad, the extension should install without issues. If you're unsure about your specific magazine, check the base pad design first.
