This is the factory OEM Smith & Wesson M&P Shield .40 S&W 7-round extended magazine.

Featuring a +1 extension, this Smith & Wesson Shield .40 S&W magazine holds up to 7 rounds. 

This S&W M&P Shield 40 magazine’s steel construction holds many quality Smith & Wesson components:

• Clear, numbered witness holes along both sides
• Plus 1 round grip-extending baseplate / finger rest
• Anti-tilt follower and steel feedlips for reliable feeding
• Impact-resistant polymer follower for high mag drops

With the M&P Shield 40 pistol as a popular EDC, these factory replacement Shield 40 magazines deliver reliable performance and improved maneuverability.  

This S&W Shield magazine is compatible with both the original M&P Shield and M&P Shield M2.0 pistols chambered in .40S&W. The grip extension on this Shield 40 magazine does not feature the aggressive texture of the Shield 40 M2.0.

This M&P Shield 40 extended magazine packs a punch with 7 rounds of .40 S&W, making this a must-have for Smith & Wesson Shield owners. Pick one up from The Mag Shack and try it for yourself.
