Pro Mag Industries Magazine for Smith and Wesson M&P9 Features The ProMag magazine for the Smith and Wesson M&P9 is constructed from heat-treated steel giving the magazine body the strength and rigidity needed to withstand repeated loading dropping and daily carry. A black oxide finish protects the steel from surface corrosion while giving the magazine a clean uniform appearance that matches the pistol s factory finish. The 20-round capacity extends beyond the pistol s factory magazine capacity in many configurations offering shooters more rounds on tap for range sessions or home defense. This higher capacity can reduce the number of reloads needed during extended range training. An injection molded follower is engineered to feed rounds consistently and smoothly minimizing the chance of feeding malfunctions during rapid fire. The magazine s spring is formed from heat-treated chrome silicone wire a material chosen for its ability to resist fatigue and maintain proper tension even after long periods of storage while loaded. Manufactured in the United States this ProMag magazine offers a dependable cost-effective alternative to factory-branded magazines. For M&P9 owners looking to add spare magazines or increase their pistol s on-board capacity this ProMag option delivers solid value and reliable performance.
