Description
Looking to increase your magazine capacity without making a major upgrade? The Tyrant CNC +5 extension is a straightforward way to get more rounds in your M&P magazines while keeping your existing setup intact. This isn't just a basepad swap either. It's engineered to work with your full-size M&P 1.0 or 2.0 magazines chambered in either 9mm or .40 S&W, bumping your capacity from 17 rounds up to 22 for 9mm, or 15 to 20 for .40 rounds.
Material Quality in the Tyrant CNC Extension
Built from aerospace-grade 6061 aluminum and finished with black anodize, this extension is made to handle real-world use. The hard anodized finish resists corrosion and keeps everything looking consistent with your firearm. The weight is minimal enough that it won't throw off the balance of your gun, but substantial enough that faster mag drops become second nature during rapid reloads.
Installation and Grip Improvements
One of the best parts? Installation takes seconds and requires zero tools. The NoBak Spring Plunger technology built into the design means you just drop it on and you're done. The serrated sides give your magazine a textured, knurled grip surface that makes getting a firm purchase during mag changes much easier, especially in high-stress situations or when you're moving fast. That's the kind of ergonomic improvement that matters when you're running drills or competing.
What Real Users Notice
Once installed, people report solid reliability over extended use, including through competition and training sessions. The included 10 percent power spring helps ensure consistent feeding with the added capacity, which is important when you're pushing those extra five rounds into play.

Frequently Asked Questions
Will this extension work with my M&P Shield?
No. This extension is specifically designed for full-size M&P 1.0 and 2.0 frames only. It won't fit compact models or the M&P Shield. If you have a Shield, Tyrant CNC makes a separate +2 extension designed for that platform.
Does the Tyrant CNC extension require any tools to install?
No tools needed. The NoBak Spring Plunger technology makes installation tool-free and takes only seconds. You simply slide it onto your magazine basepad and you're done.
What's included with this magazine extension?
The extension comes with a 10% power spring pre-installed to ensure reliable feeding with the added capacity. That spring is tuned specifically for the added five rounds, so you don't have to worry about feeding issues.
Can I use this extension with my factory M&P magazines?
Yes. This extension works with factory Smith & Wesson M&P full-size magazines, as well as aftermarket M&P magazines. It's compatible with standard M&P magazine pouches and accessories without any modifications needed.
