The Henning Group Magazine Extension Kit for  Smith & Wesson M&P 9mm increases magazine capacity from 17 to 23 rounds!  The design of our extension is a true extension of the internal shape of the factory magazine tube. Combined with a stainless steel, 13-coil magazine spring it is a proven and reliable solution. Our Smith & Wesson M&P 9mm magazine extension is CNC machined from 6061-T6 billet aluminum. This extension fits the USPSA 141.25mm gauge, and is legal for Carry optics, Limited Optics, Limited & Open divisions in USPSA. 

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

We have two options for springs:
A. Henning Group spring (using factory follower). Installed on a 17 round mag, our spring ensures proper function.

B. MBX Follower and Spring increases capacity from 17 to 24 + 1. No Lock Back! Only for 17 round mags.

Works with all magwells we have tried, including the following:

Floyds Custom Shop
