Tyrant CNC TDMPMAGEXFSGREY Magazine Extension Fits S&W M&P 9/40 5rd Compatible w/ Full-Size M&P 1.0/2.0 frames Grey Aluminum

Add five rounds of capacity to your Smith & Wesson M&P 9mm or .40 with the Tyrant CNC magazine extension, built for full-size M&P 1.0 and 2.0 frames. This grey aluminum basepad isn't just a simple capacity boost—it's a precision-engineered accessory designed to integrate seamlessly with your pistol's ergonomics and handling. Whether you're running drills at the range, training for competition, or building your carry setup, a five-round addition matters when every shot counts.

Tyrant CNC engineered this extension with a focus on reliability and usability. The aerospace-grade 6061 aluminum construction withstands repeated use and disassembly without degradation, while the NoBak spring plunger technology locks the extension securely in place yet allows quick, tool-free removal when needed. That's the kind of durability and convenience that separates quality accessories from the rest.

Function meets grip with knurled edges running around the basepad—they give your fingers positive purchase during magazine changes, especially helpful when you're juggling five extra rounds and speed matters. The serrated sides add both tactile control and a professional finish. At 48 grams alone and 130 grams when fully assembled, it adds minimal weight while delivering genuine capability gains.
