Warne 3306 Magazine Extension S&W M&P 9/40 +3rd 9mm Luger / +4rd .40 S&W - Black

The Warne 3306 magazine extension is a drop-in base pad upgrade for S&W M&P 9/40 pistol magazines. When fitted to a 9mm Luger magazine it adds +3 rounds of capacity; when fitted to a .40 S&W magazine it adds +4 rounds. Constructed from aluminum with a black finish, this extension replaces the factory base pad on S&W M&P 9mm and .40 S&W magazines and is engineered for improved handling and added firepower.

Warne designed the 3306 with an ergonomic shape and integrated finger grooves that improve purchase on the magazine during reloads and also allow the magazine to be stripped from the handgun should it become stuck. The extended footprint provides additional grip length and better control without altering how the magazine seats in the pistol's magwell, giving the user a more confident reload on the clock or under stress.

Whether you run an M&P 9mm for duty, competition, or everyday carry, or an M&P .40 S&W on the same platform, the Warne 3306 delivers added capacity and a more positive handling profile in a lightweight aluminum package. Designed to fit factory S&W M&P 9/40 magazines. Model 3306, black finish.
