Henning Group's Magazine Extension for Smith & Wesson M&P 9mm. This extension is made to make your magazine legal for USPSA 141.25mm gauge. For maximum capacity, add the follower kit. 

Our latest design includes numbering dots, serrations for light side grab and a reinforced wall thickness. 

We have two options for design and purpose:
  • Non-Magwell version for Carry Optics and general use
  • Magwell Ready specifically designed to work with M&P with magwell and no magwell.
Note: The non-magwell has the retention pin in the back which is the easiest to use. The magwell ready version has the retention pin in the front.

We recommend adding the optional MBX Extreme follower and spring kit to increase capacity to 24 + 1. The spring is longer and designed to work with our extension.
