ProMag Smith & Wesson M&P Shield Magazine 9 Round .40 S&W Mag (SMI 31)

This is a Genuine 9 Round ProMag Replacement Magazine for the Smith & Wesson M&P Shield semi-auto self defense pistol. These 9 round Smith & Wesson M&P Shield magazines are GREAT to carry as spare mags to give you some extra ammo for defensive situations and they are GREAT at the range!

Constructed from heat-treated blued-steel, components molded from ProMag’s own proprietary Mil-Spec TECHNAPOLYMER® and an tough anti-fatigue spring, so you can keep the magazine loaded and at the ready for up to six years without concern!

The finish provides a low maintenance surface, and aids in reliability. The Mil-Spec polymer butt-plate and removable grip extension helps with quick magazine changes and it also helps to prevent “printing” when carrying concealed.
