ISMI Smith & Wesson M&P Shield EZ Magazine Spring Capacity Increase

Now available at NDZ Performance, a new ISMI magazine spring for the Smith & Wesson M&P Shield EZ designed specifically to work with our plus 2 capacity extension magazine plates. These springs feature a spring weight that is made to reliably load the additonal rounds provided by our capacity extension plates. ISMI springs are high quality and made of Chrome Silicon, which has a higher yield point of material than OEM springs, which are made from music wire. This means that when fully compressed, it is under less stress which allows the material to last longer than any OEM (music wire) equivalent. The result is a spring that doesn't take as much initial setup as an OEM spring which exerts more load for the entire lifespan of the spring. Adding to more rounds to your Shield EZ has never been easier with parts from ISMI and NDZ Performance.

• Designed to work with our +2 capacity extension magazine plates for the S&W M&P Shield EZ, giving you up to 10 rounds in your mag.
• For 8 round, 9mm magazines only; will not work with .380 magazines.
• Made in the USA.
