MAGFIX S&W Shield 9mm/.40 S&W Extended Magazine Base-Plate

The Shield MagFix® is an enhanced magazine base pad and sleeve for the Smith & Wesson® M&P® Shield.
The MagFIX is the result of 4 years of research, product development, and design. The MAGFIX does 3 simple things: 1- It locks the sleeve in place. 2- It adds texturing to improve your grip on the gun and the magazine. 3- The shape of the MAGFIX helps the magazine to drop freely when reloading.
