If you carry an S&W M&P 9 or M&P 40, you know that factory magazine capacity can feel limiting in a defensive or range scenario. The Tyrant CNC TDMPMAGEXFSRED magazine extension adds five rounds to your standard M&P magazines, giving you real utility without breaking your carry ergonomics or reliability. Built from red anodized aluminum, this extension pairs solid engineering with a look that stands out on the range.
This magazine extension is engineered for full-size M&P frames—both the original M&P 1.0 and the newer M&P 2.0 generation. It's a straightforward upgrade: bolt it onto your 5-round magazines and gain capacity while keeping the same grip profile you're used to. Tyrant CNC is known for precision machining, and it shows in the fit and finish here.
Whether you're building a duty gun, setting up for three-gun, or just want more rounds downrange at the range, a magazine extension is one of the easiest upgrades you can do. The red aluminum finish gives you the option to color-code your mags or just add some personality to your setup. Practical and affordable, this is the kind of accessory that pays for itself the first time you reload.

Yes. The Tyrant CNC extension is engineered to be compatible with full-size M&P frames across both the 1.0 and 2.0 generations, so you can upgrade magazines for either gun without worrying about fit.
This extension fits S&W M&P 9mm and M&P 40 S&W magazines. Make sure you're starting with the correct caliber magazine before adding the extension.
The Tyrant CNC extension adds 5 rounds to your magazines, so a standard M&P magazine will hold five more rounds once the extension is installed.
Magazine extensions are straightforward to install—this one simply attaches to your magazine. However, we recommend checking the manufacturer instructions or consulting your local gunsmith if you're unsure.
